Just did one myself 3.3v rail capacitor. Diagnosed using hot and cold on capacitors to pinpoint problem. After replacing it worked and bad capacitor read correctly at 47uf but I guess had bad ESR. It wasn't bloated either. Can never trust an electrolytic like a politician.
Obrigado por suas aulas. Pela sua experiência em fontes de alimentação, poderia informar se posso substituir nessas placas um capacitor de 680 uF por um de valor 820uF com a mesma voltagem?
Please provide a link to the store where you can buy these diodes that you insert instead of strips illuminating the matrices in LED TVs. Pozdrawiam z Polski.
Is the back light 3 rows each 7 bulbs connected two rows in parallel and one in series? If all bulbs in series the voltage required is 21x6 volt= 126 but it lits up at 70V hence my doubt.

Hello sir, I have a Hisense with hybrid board. Standby light is on, when pressing power image comes on but no backlight and turns off within a second and gets stuck in loop. Changed capacitors and still no luck. In circuit capacitors measure double value. Is that normal?
I am interested in repairing this TV and am willing to pay you for your time. In standby the controller chip is warm, is that normal? DC voltage are present but in standby in one circuit, the voltage continually drops before pushing power button. Thank you
Hi. I watch your videos with great interest I have a request. Could you ever make a video of electrolytic smd capacitors mounted on the first layer of the motherboard, and how you identify which is damaged and which is functional? Thank you for the videos and best regards.
@@mahmoudnaser453 because they are bloated, and first seen on the video. I known they are not the reasons why the driver is not working. If I dont changed it may viewers ask why?I hope you understand.
Sir, a personal question? Are you a member of an IP Tribe? Just listened to the background conversations and heard some accents that sounds familiar. Thanks.
Please change all the led strips otherwise the same problem may occur soon (because other led bulbs life will be reduced so same problem will occur again soon) Thanks
Your diagnosis bit confusing 1 St you said backlight not glowing & Measured backlight voltage is not boosting then why are you going to 12 volt & 5 volt lines instead of backlight section.
Sometimes addressing the visible issue, like a bloated capacitor, is the first step in troubleshooting. It's essential to fix any obvious problems before diving deeper into more complex or hidden ones. This can help prevent further damage and ensure a more thorough inspection of the system.
good sir tevs...maraming salamat po sa pagshare.

😂😂😂
Thank you for the tutorial. I learned capacitors can also be a root problem too backlight issues. Keep up the good work.

Thank you for sharing your wisdom 🇰🇪
MAESTRO thank you very much for the video.👍
Thanks a lot I'm learning a lot more from your.but is the problem after replacing the cup 470uf35v it gets hot and blow up

I loved.god bless you
nice work master 👍👍👍
Keep up the good work Sir u a d best thanx a lot
Hello. Please show us always the model number on the sticker on the backside of the TV. Good video's and good job. Thanks. Andy.
Please give me a link to buy single leds for backlight which you are using when strips not available
Good job 👍.
Great teacher
Thank you! 😃
Great mastar❤❤
❤ thanks sir for knowledge

they all connected in series, the LEDs are 3 volts
Sir, can you tell me what is the value/ marking of the rectifier diode? Because mine is burn out. Thank you!
Werey good job sir thanks for you
❤❤ thank you sir❤❤
❤❤u r great teacher❤❤
Goodjob master
Greater job
Good job 👍

bL tester can be use to check the defective backlights
watching master

Are these lights in series? Like Christmas tree lights? if one is bad it will disable the others?
You're right
Tu es le meilleur je veux vraiment être formé comment faire
Thank you sir ..
Helo Sir, does Sharp TV will light-up when the main board not connected ? Note : My TV has Power board and Main board separated.
No idea
Good job..
Nice information sir
Thax alot
Good sir
I Like this too
Mr . Tevz you must first testing the led driver first when you measure the voltge
That is exactly what I did.
No,you first Chang tow capistane 470mf/16v&10v,I think so

hahaha hindi
👍
thank you sir
sir, saan ang calibration center ng fluke multimeter dito sa pilipinas? salamat
Negative idea
Love You sir🇧🇩🇧🇩🇧🇩🇧🇩
🤟
❤
why didnt use led tester
Multi tester can test it
Pleaae show your fork type testing probe in next video
fork probe? clip and high voltage probe all I have.
@@tevzTVTevatronics I am from India how can get it
👍👍👌👌
good
