Faulty HDMI Port on LG Television. No Signal Fault
ฝัง
- เผยแพร่เมื่อ 27 ส.ค. 2024
- In this video I demonstrate how to fix your faulty HDMI ports on your television. If your TV shows 'NO SIGNAL' then by heating up the HDMI chip you can once again enjoy them working. It shows you how to trace the HDMI trip and it getting fixed in real time. This FIX is only a short term measure and the HDMI chip will fail again but you may get a few months out of it (or a few days). Make sure the TV is unplugged/disconnected from the electric power supply before attempting this repair as electricity from a TV can kill.
Si alguien de habla hispana llega a este video, déjenme decirles que no tenía señal de HDMI ni de entrada de componente, hice lo que el vídeo explica y aunque tarde un poco más (unas 6 veces haciendo lo mismo) luego apague y desenchufe lo deje 10 minutos y al volver a encenderlo funciono!! Asi es que gracias por la ayuda!!
Haré lo mismo, ya que presenta el mismo problema mi pantalla LG
@@sergioivantr espero te haya funcionado
Aun funciona ?
@@victorhugoviverossuarez9237 a mi si, aún me funciona... Este problema se me. Presentó despues de haber tenido el tv apagado por un par de semanas en ue estuvo en un soporte pegado a la pared de concreto, no sé si eso habrá influido en que no funcionará, lo hice lo intenté bastabtes veces con el secador hasta que me funcionó. Saludos
Y la solución es permanente o hay que hacerlo cada cierto tiempo?
I really love that you used the mirror and could show how it worked immediately. Great help!
I'm blown away, I was extremely sceptical but after a week of head scratching, here I am playing Xbox again! Thanks very much for the video
My LG tv HDMI ports all stopped working tonight. I followed these instructions and wow !! now working perfectly, thank you.
Is it still working for you ?
@@EternalNovA Yes 3 weeks on and still working perfectly, fingers crossed.
My tv did this so I'm gonna have to take it apart and do this and see if it works
I just did this with an lg 50PX950. 60 seconds with a hairdryer was all it took. Not sure how long it will last, but a miracle for now. The TV is a boat anchor otherwise. Thanks for this posting.
Jim,
don't through it away, it is very easy to fix it. just buy the IC and replace it. I put the IC number on my message above. Check if the main board use the same IC, normally it is always the same one.
It worked!!!! I tried that on a 50 inch LG 50PK950, and after a few time with no Signal, HDMI started working again! I have to add that the total time of Heat I applied is 2 to 3 minutes, in attempts of 30-40s, then stopping. HDMI came back after some time, not instantly after heating
hello hot air repair still holds? thank you
HEY MAN I DID THIS WITH CARDBBOARD UNDERNEATH AND YOU MADE MY DAY SO MUCH BETTER. I'VE BEEN HAVING THIS PROBLEM FOR A LITTLE MORE THAN TWO YEARS, AND I HAD NO IDEA BECAUSE I WAS SCARED TO DO THIS BUT THANKS TO YOU, MY TV WORKS SO MUCH BETTER NOW !!!! THANKS MAN I LOVE YOU
THE CARDBOARD MIGHT SMOKE UP A LITTLE BIT SO LOOOK OUT FOR THAT. IT SMOKE FOR ME BECAUSE I HAD GLUE RESDUE LEFT ON IT. JUST CUT IT OUT AND STICK IT INSIDE. AND KEEP A EYE ON IT TO SEE IF IT'S SMOKING. THANK YOU AGAIN
This is insane. I can not believe it actually worked. Ran the dryer for about one minute push the input button on the remote, reselected HDMI1, TV turned off then turned back on by its self and now I can see my Xbox dashboard. I’m curious how long this last. Very impressed.
hello hot air repair still holds? thank you
@@kirokiro6591 got rid of the tv a while ago but it still worked.
Like you said it's a shot term solution. The problem is that one or more pins on the HDMI chip has lost it's connection to the board because of expansion and contraction over the years. The easiest , permanent fix is to use a soldering iron and solder wick. Lay the wick over the all the pins on one side of the chip and then slowly drag the hot iron down the wick . Do the same for the other 3 sides. Be careful not to pause to long as you go over the pins since you don't want to suck all the solder out from under the pins. The goal is to heat the pins just enough to get the solder to turn liquid without sucking the pins dry. Sucking them dry is just about impossible anyway but heat is the enemy of chips so don't hang around too long with the hot iron as you go along.
Using the soldering wick makes it virtually impossible to solder 2 pins together by accident. If you just run the hot iron over the pins without the wick it is VERY easy to solder 2 pins together.
Well is this method a permanent fix or short term too?
@@DJrockSStar -It's permanent . I forgot to mention that brushing on some flux over the pins helps the solder to flow better.
@@TheNYgolfer Ty for bothering to post this I'm a huge fan of doing this sort of thing yourself, this appears to be the same issue as the red ring of death back in the xbox 360 days, i wonder if a lot of these port issues are simply the thermal paste losing effectiveness rather than the components themselves being bad, i mean they're like metal and crystal and shit it seems reasonable that they wouldn't just go bad after a few years pretty durable materials, whereas the paste isn't really by comparison.
Late reply this may not work if the controller chip for the hdmi has completely fried!
A mi me sucede al ver los canales cual sera la solucion. Solde los pines del varicap y no funcionó
Hey I did this to my 32 LG that was sitting dead in my den for about a year now because the hdmi wasn't working anymore. Tried your fix today and it worked! Don't know how long the fix will last on the chip but I googled the chip and will be replacing it if this fix dies. But in the meantime I now have a 32"in. computer monitor. Thanks very much man!
is it still working since then? I have the same tv with the same fault
Brendan Young unfortunately not anymore. It lasted for about a week then hdmi died again. It did say in the vid that the fix may or may not last, I also ordered the chip on ebay and have installed it unfortunately it still didn't revive the tv.
@@AltitudeAerials I'm also going to purchase the chip. Have you tried once again to replace it? Thank you!
This is my solution. Suddenly all of my HDMI ports from an 50 inch LG Tv stopped working. I've watched a lot of this videos. My HDMI ports were listed on the menu (that mean that they have power) but always showed NO SIGNAL. I've tried to use this method but decided to follow Carlos Frontado (user in the comments) and bought the chip that is responsible for HDMI ports (2 USD on ebay) and found a profissional that changed the chip on the board (a TV repair profissional) and voila...it now works. This is my advice. Change the chip.
Thank You. This works!! I have a 48 inch LG about 5 years old and it was working perfectly up until recently. The TV is located in my basement rec room that isn’t used that much anymore since my son moved away. Like most homing pigeon kids he returned however the TV would not work on HDMI. I think now that he’s using it again and just getting it back warming up again the problem may go away permanently.. Your right that it doesn’t take much heat. In fact I decided to try it by just heating directly onto the back without even disconnecting anything. I used a 1200W heat gun about 6-8 inches away for no more then 15 seconds and the HDMI ports became available again. Easiest TV Repair Ever. Thanks Again.
Thanks for this. I impressed my husband with my knowledge! I showed him the video and we fixed it together.
thank you. big help. fixed by LG 60LD550. I reflowed the CPU processor as you did, but also did a chip next to the 3 HDMI inputs (saw someone else say this was the problem). So I used flux on box and then reflowed with a heat gun and a meat thermometer. Worked like a charm. Let's see how long this lasts. I had paid an internet company to fix this card about 4 years ago, they probably did the same thing. Thanks again. Good video.
Thanks for your video, my lg do the same fault years ago and I send it to an technician to "rebail it" and it was work for a few months then it fault again. So I open it and take a look at the main board and see some marks on every chip pad, like if it was heated with and soldering air gun. will try to fix my lg like you explain here and write to you if it works . Thanks again, cheers from Argentina!!
Thanks for info. All i did was take a hair dryer and heated hd ports and inputs on back of tv. 5 minute fix working so far!
Doug Steepe did you take off back or u just heated it up with tv back on?
I did the same thing with my LG tv, and after that it worked fine, but definitely the chip that control the HDMI ports has to be replaced. it could failure again.
thanks Sir.
Carlos Frontado vi em outro post vc conectando que trocou o chip. Como fez isso? Vc mesmo fez?
How long did fix last you?
Hey
You saved my LG 42 TV!!
What a wonderful tip ever!!!
I owe you^^
Same TV, same problem. I´m gonna cook it this weekend and try.
Is it still working? Greetings
:) Bravo buraz buraz! Ne samo da si opravio telku, već si i one gaće iza osušio! Respect!
Just did our 60" LG Plasma. Same issue. Heated the flat chip up for about a minute at roughly 3" away, let it cool for 3 minutes and boom it works! NICE and thank you! 8/30/2018
Before I took my TV apart (or bought a new tv) , I investigated other possible solutions. Adapters: If you choose the male hdmi with female vga (which is also 1080 on the back of the TV) AND the audio output, you can do a permanent fix.. I found several on Amazon for $8.00 even including a mini-hdmi to usb and the 3mm audio. Works wonderfully. And the hairdryer solutions ? My electrical engineer friend says it's NOT the chip that is fixed by the heat but the micro cracks in the solder in the board, that expand and reconnect once heated. And slowly recedes and disconnects. This way it's permanent.
Your engineer friend needs a bit of an update. The QSOP Chip actually has maybe just one detached leg causing it to have a little space between the contacts.Due to the heat expansion the leg gets a bit larger and it may touch the solder of the mainboard like it should , then due to surface tension or adhesion it actually picks up a small bit of solder paste and reconnects with the main board. BUT because of the cold drawing back the leg again to its original size it pulls this solder back in a fine line and only the fine line of solder >( like a spider web string ) is now connected. NOW you have HDMI Signal again , BUT because of the process of shutting off you tv and then turning it back on there is Thermal stress that will likely break this little spider string in the near future. The Proper fix is : Put the Mainboard flat on the Table and dump a coin on it. Use a syringe to put FLUX on it. Heat the Chip to about 240 to 250 Celsius for about 15 Seconds until you can MOVE another component with a plyer next to the chip. If you are able to move another component next to the chip that means you have reached the proper temperature. you can now withdrawal the heat SLOWLY ( about an inch every second. This will help with the thermal contraction being done almost properly. The weight of the coin ( anything ,,, maybe just a cent or two ! )will put enough weight on the Chip to put it down properly. .... NOW if things are still not fixed then you MAY have a broken trace (this is where the fun would start for me ! ) ... To pinpoint the issue further you could use some ice Spray , but proceed with caution.Even a TV that has been disconnected for 6 month may still hold a charge up to 300 Volts or more in its capacitors... It wouldnt be fun... Trust me :) Kind regards Frank
Just bought a 42' lg with this problem for £20 (only needed vga to use as a monitor)
Gonna give it a try tomorrow.
Thank you very much, since I have warmed the room on su tv LG 42LE8500 my tv works very well
thanks mate i have just fixed my tv in your way all working now i am so happy i could do it with your help awesome job
This is awesome. I'm reading how many people have got their TVs to work and will give it a shot. 👍💯 Great video.
dammit it happens with all LG TVs, its also happened with mine. LG should recall all those TVs its chronicle issue as I could find. thanks for the video.
Thanks a lot, man. You save me from buying a new TV. Now my 10 years old TV work like a new one. I spend only one hour of my work :)
How is it holding up?
YES! That's awesome, It really works! No need for the smelling, smoking oven baking process, a simple hair dryer could manage to put the TV working again. Thanks for sharing with us!
Is it still working?
How long did fix last?
Ευχαριστω πολυ με εσωσες , αυτη η ιδεα σου πετυχε στη LG 42LE8500 με νεκρες και οι 4 HDMI
αγοραστηκε το Απριλιο 2010!
Great!!! It worked to my LG 47!! Thanks boss!! And it's one more tip. I didn't remove the back cover, but blew into through the duct. It worked when I blew about 30secs, and I did 1min more for just in case. It took just 2minutes without any tools!!!!
Is it still working now with one-time fix?
@@jun9886 Yes. It still works well. Ironically, I thought heat was the cause of the breakdown, so I put a cooler on the back cover duct a month later. It only costs $5. I stuck a 60mm usb cooling fan with double-sided insulation tape. That's all I did. Good luck dude.
Thank you
thanks for the tip. worked for me too on my old LG 55 '12. didn't have to take out the backside, i just put the hairdryer very close to the duct. no tools needed.
@@juicychicken6779 No problem dude.
Hi everyone! No need to heat the chip! The problem 99% of times is just the dirt or the oxidation between the teeth of the two chips that are shown in this video! That's the only solution, also because many of those main boards are no more purchasable
Cheers for the video man, helped me salvage a TV found on the side of the road 🙂
i fixed my lg tv and have been using it for 3 years you need solder flux and hot air gun not air dryer as that will simply just warn the chip up for a short time
Thanks! My old LG TV survives planned obsolescence a little longer.
Muchísimas gracias! Acabo de hacerlo y quedó perfecto! Me dio un poco de miedo porque demoró bastante y justo cuando iba a para apareció la imagen! Muchas gracias! 6 años guardado estaba
aun le dura amigo o solo funciona cuando esta caliente ese circuito ???
@@humbertodefilippi8214 recien acaba de dejar de funcionar. Voy a hacerlo de nuevo
Cuánto demoró en regresar la señal?
Hi ! Thank you for the nice video ! I love fixing theese boards ! ,.,, Just get yourself some NO CLEAN FLUX and set your heat to 250 Celsius Temp. for about 15 seconds evenly distribute the heat to the whole chip while covering everything else around the chip with aluminum or better :) it will be a permanent fix ! ... Kind regards
Frank
MY LG 55LX9500 all 4 ports HDMI stopped working. I will try to heat up the chip to see if its come alive. Thanks for the video
Any luck?
Lg should take responsibility, the INFINIA series televisions are destroyed alone by bad bga welding of the processor, if they look for LG LED TV failures they will find thousands and thousands of victims, out of warranty no longer get spare parts, the reballing could be a solution but few do it well and give guarantee of lasting work, as I say LG should take care more to their buyers is a shame the abysmal amount of users damaged by this failure even in more modern televisions.
Thank you. I tried this fix and it actually worked! I wonder how long will this fix work in my case?
HOLY SHIT!!!!!!!!!! Awesome! thanks!!! I had no idea that you UK guys pronounced "HDMI" like that... very cool. I saw one of your other videos... thanks for the info. I ordered a board for a 60-inch plasma today... can't wait to fix
Monty Montaquila where did you order it from? Thanks.
good info, liked. i just made a video that fixes this issue long term. search- 3 ways to fix HDMI problems

I just did this, fixed the HDMI port on my LG 43" 4K TV.
I was having problem one day HDMI port just blurry on port 1, port 3 doesn't work at all. wigging port 2 broke port 2 as well. Heating it for a minute, back in working condition.
It worked! My neighbor tossed his 42" and said the part was no longer available to fix the inputs. I figured maybe eBay might have a board. I did find one, but it was too expensive for repair of a 10yo TV!
Propped the hairdryer right up to the chip with my opened TV lying flat and let it heat for 5 minutes. I also saw that a screw was missing at the corner of the board. Neighbor had taken it apart already, so maybe he lost one. I found one to put there. Gotta make sure the board stays flat! I sprayed rubbing alcohol into the hot ports and swabbed them a bit. Back together, and all good! Thanks!
Another TV I fixed had a known issue with a screw not being grounded. Something like that. Easy to repair except someone else had ruined the board trying to DIY solder. I spent money for a board anyway because it is a nice older plasma, large screen. Still working.
Hello! I have the same problem with LG TV, other model. After do that, it's still working? For how long?
You Sir helped me saving another LG TV! I appreciate your video, thanks a lot, it did work like a charm and like advertised ;)
Is it still working? Greetings
Well I had a TV until I did what this dip said now I don't have a TV at all now I'm into a black screen standby power only thanks a lot and I didn't even heat it up as much as you did all I got to say is to all the people watching this video don't do it just buy a replacement board messing* with a processor chips not a good idea
The process is easy to follow. The video is so shaky that it is too difficult to watch for me. It may not be so for you as I have vision insufficiency that make seeing movement challenging.
Just tried this. worked first time!
Hallo,
4 h long time have u been heating the tape pls ?
Suprisingly it is working fine with me. Thanks a lot bro.. ♥️♥️♥️
Wouldn't it help to glue a passive heatsink on the chip? like the ones available for the raspberry pi.
Had the same problem with my lg,no signal,fast foward 6 months later and bought a roku stick for my other tv and though what the hell ill try it on my lg,plugged it in my hdmi port and usb port(to power the stick) and for some reason my hdmi signal worked perfecly,never had a problem since
I've just tried this on my LG 42LV4400 and it worked, of course the chip looks different but its the chip the goes to the HDMI ports.
Thank you so much man, really useful
yes that is a good short-term fix and the other one when you bake in the oven for 10 to 12 mins,the way i have solved the problem is I have a Freesat box that has a scart plug on back so my tv also has a scart so just put an old scart lead in and now working, also the blue ray player have bought an HDMI lead to Component lead yellow-red white,and for my games console bought a Wii to Composite lead .you can also get component to component and component to hdmi.this is the way if you dont want to take the tv apart.
Thank you so much man, really work THANK you again from Athens
lg 55le8800 con lo stesso problema delle porte HDMI, risolto con il phon per una decina di minuti. ha ricominciato a funzionare dopo altri 10 minuti di raffreddamento.
grazie mille!!!!
Cool thanks. My LG 42" HDMI ports packed up last night so im looking for solutions. Ive got an adapter with five ports for Virgin box,xbox, surround sound n a flat cable running under carpet to laptop next to sofa to stream movies etc. My TVs only 3yrs old cost £550 so not impressed,great picture tho. Il have to buy a hair dryer n see what happens or i could pour hot water on the chip but the result could come as a shock!!!
Saç kurutma makinasıyla denedim işe yaradi. Mucize gibi. Bendeki lg tv chipi de tda19997hl/c1. Tekrar bozulursa değiştireceğim.
Yaptiktan sonra tekrar ayni sorun olustumu acaba?
Thank you so much. It’s work !!!!!!!!! from Thailand
I have the exact same model tv and this fix did not work for me
Moltes gràcies per la informació, em va anar perfecte la teva solució. (fins hi tot no va caldre desmuntar la tapa del darrera). Vaig estar apunt de comprar una televisió nova i ja fa 6 dies que encara funciona.

Excelente detail video, ive looked at many youtube video and this fix didnt work for me for a lg47 inch tv.
I normally fix video game console so not familiar troubleshooting tv. I've replace the smd hdmi chip with new one and still didnt work either.
Is there another section i can take a look and see what else can be the cause of this issue ?. I saw tampatec videos too, excelente both of you. Bravo. Thanks for sharing.
This works with a hair dryer. Verified. Thank you.
On my LG LE 5500.. it is not the hdmi chip..( TDA19997HL ) but the processor with the big heatsink that have to be reballed.. but i -repaired- with a mechanical solution.. put something between backpanel and heatsink.. so that there is pressure on the heatsink. or a plastic screw.. so you can adjust..
Gracias gracias desde Venezuela , hoy presento mi tv la falla y mi esposa busco por web. y lo logramos ya volvió a activar el HDMI. Con el secador de pelos de mi esposa le aplique como 10 min. ya que es de baja potencia pero logrado. Excelente. Muchas gracias.

Why would anyone believe a brit who has angry birds on his TV??? Just teasin! This was great, I'm going to try it on my TV and see if it works until I can find an affordable replacement hdmi board. Thanks! Cheers!
My TV Humax recorder regularly cuts off all of a sudden saying
no recordings! it’s just happened and unplugged HDMI cable, re-fitting and then all worked fine until next time few hours later or next day.
Any suggestions appreciated, maybe a new cable will fix it but i feel it’s more serious.
My LG hmd socket is in a standing position, the location of its installation soldiers is not clear, I want to replace it but is not possible
Nice
Yes, it works, but it last not too much, and nobody know it. The problem is the chip (IC) TDA19997HL/C1, and the best solution is changing it. it is not necessary to change the electronic board, just change the chip.

So i have to do this everytime i swich off and on again when i was to watch TV? Becouse when i swich off the TV it doesnt Work anymore
Bonjour ça marche très bien sûr ma télé je suis très contente merci pour la vidéo.

Any recommendations? Thanks for the video, its brilliant
thanks mate! Its working!!!
I tried applying some solder paste to the microprocessor where the hdmi goes to and heated with a blowdrier. When I turned my TV on there was some smoking and the screen flicked, now I dont even have any image. What happened?
It might be worth getting some solder wick and removing the solder paste to see if you can get the screen working again. If you have a VGA port then you can get a HDMI to VGA converter and then you can connect up the HDMI equipment to the VGA port if the HDMI ports are dead.
By applying solder paste you shorted out the connections and probably fried the chip. Not the heat that fried it but current through the short.
You shorted out your tv with the solder...
Plug in RCA Cable too, it's work for me :).
Sorry for bad English, GBU.
Wondering if you could give me any advice, basically my hdmi port will not work for my PlayStation everything else is fine. I’ve changed the hdmi wire tried many and still no signal. The tv is about 15 years old one hdmi port.
