FAQ's:
Q: What if I try all these steps and it still wont work?
A: If all of the steps here didn't identify the issue and the computer didn't display to an external monitor then we are left with your motherboard being the problem. It should be replaced. You can see an example of a motherboard replacement here; • How To Replace Lenovo ... . Let me know if you need help finding one or with the install :)
Q: My computer displays to an external monitor but wont display on its own.
A: If your computer displays to an external monitor but not to its own LCD, then your issue is most likely with your LCD or LCD Cable. Try 'Reseating' the cable first by unplugging it from both ends. Then, plug it back in. If that does not help, replace the LCD and Cable one at a time. Let me know if you would like help locating the correct parts :) - วิทยาศาสตร์และเทคโนโลยี

Thank for for taking the time to make this video. I know that you are helping a lot of people. I think I have the LCD issue. Fingers crossed that it is an easy fix!
Man you're a legend; I was going to buy a new Laptop cos I gave up trying to fix mine, or even send it to a repair shop. That is until I came across this video and did the bad RAM test. It worked like magic. One of my RAMs was causing my laptop not to turn on for some reason. You saved me money and stress man, thanks a lot - wish you the best

Very coherently explained - you'd make a good teacher! My Dell goes dark across one side of the screen. Plugged it into an external monitor and I get a bright, clear output, so I guess it's either the LCD cable or the LCD screen. Fingers crossed - will get back and let you know the results.
Yes, good troubleshooting !! Good luck !! Let me know how it goes :)
Hi Robert, I am having same issue as you. After replacing the bottom cage of the laptop because hinges were broken, once put together, screen was faint. Can barely see anything. However, when connected to external monitor, laptop works as expected. Though can not see anything on the laptop screen. Were you able to fix your issue? if yes, what did it for you?
Thank you. You just saved me a bunch of hassle and I was able to pull my files from my computer now that I can see the screen. Thank you so much your awesome. I hope you have a great day and I hope much joy is headed your way.
Thanks !! Glad this video was helpful :):)

Just an FYI: For me and the Samsung Notebook 7, Windows updates replaced the display driver which was causing the black screen. Every time after an update the computer came on but nothing appeared on the screen. Plugged it up via HDMI to the tv and it showed everything working perfectly fine. I had to hunt down an older driver and install it. Before replacing the hardware, make sure the dreaded Windows updates aren't ruining your older laptops.

I tried replacing my keyboard on my Dell G3 3579 and now it won’t boot. After pressing the power button it turns on, has a blank screen and the fans seem to go into overdrive. After 10-15 seconds it turns back off.
I’ve tried reconnecting all cables and resetting the CMOS.
After first replacing the keyboard the plastic clip that holds the ram in place broke and I had to switch slots… so now unfortunately I can’t test the original slot.
What do you suggest should be my next steps?
Sounds like you may need a motherboard replacement :(
@@PC_Monkey damn. I thought you would say that! Thanks for the super quick reply 🙏
I have a Dell 7559.
The screen goes black and when I Unplug and replug the battery cable as well as the RAM it starts to work.
Also, once the computer is on with it's screen; and at this point now i connect it with an external monitor, the laptop screen stops functioning even if i remove the hdmi wire and then it only works with the external monitor from that point.
From what i have seen on the net, it's a common issue with this model.
Any suggestion would be great. And could this be software issue ?
thank you work it

Great video. To expand the question just a bit, if I may....my Dell 1545 boots up and displays the screen fine for about 2-3 minutes, then the laptop screen goes blank, but if I have it connected to an external monitor, the image is perfect. Having watched a different video, I successfully replaced the screen inverter, but I still have exactly the same problem.
Haven't tried the RAM test yet, but I'll have done that before you have a chance to respond, and of course, if that should solve the problem, I'll update you. But I haven't seen this precise set of symptoms described in any other posts, so I'm wondering what they might suggest to you.
Thanks!
I would assume that is an issue with the LCD or LCD Cable, if its displaying correctly to an external monitor. I would try 'reseating' the cable first. If that fails to help, replace the LCD and LCD cable one-at-a-time until you find the issue
I bought a new battery for my dell, and when i put ON the laptop with the battery in it and AC power, the laptop won't give any, but when i power the laptop without the new battery it comes up well and then i insert the battery and it charges. If i turn it off and power it with the battery and AC it wouldn't give any display until i power it without battery. Please can you help?

Amazing video.. I amsuffering through the same issue and some has told me to change the motherboard altogether but i think i have to go through ur techniques first.. Besides, what motherboard should i use for DELL Latitude E6430
Your computer turns on but the screen stays black? If the screen is black, what are the signs the computer is on? Lights? Sounds? Fan?
Is this your motherboard? ebay.us/x8B7IK
@@PC_Monkey yes buddy
.. Everything turns on... Now i will check my ram first.
How about when you plug a generic pnp monitor into the hdmi and it blacks both screens and doesn’t recognize the monitor, monitor migrate error basically
Hi! Lovely video. I have the same issue but with a flashing error code from the led by the power. Two amber, two white = no memory.
I don’t think this is the actual problem though. I changed the battery a few weeks ago and then last week the cpu fan seemed to stop working.
Later the laptop started to do a diagnostic test and beeped loudly saying the fan wasn’t working.
I ordered a new fan but in the meantime the laptop continued to work. We just used it for light tasks and it didn’t seem to be overheating. Then I struggled to login as the keyboards was really slow to respond. Now it is at the stage of your video where not even the logo comes up, just the keyboard lights and a little bit of heat from the processor area.
The RAM seems fine and I’ve orders a new CMOS in case.
I’m tending to think it has gone into a safe mode as it knows the fan isn’t working? Or does the error code mean there’s something more sinister going on, maybe the motherboard?
Any help would be amazing thank you

hi, and thanks for the vids. I just replaced a cracked screen on a Dell Insperion 15 3000, no problems until I powered it back nup, I feel the HD spinning up, but screen is blank still, the unit worked before. Any thoughts?
Does it work when attached to an external monitor?
@@PC_Monkey it's amazing hoe many people I see you respond to, and none of them respond back
I got a quick question for you. So I got a Dell M4700 just to mess with Fusion 360. Fusion wouldn't recognize K2000 gpu so I was recommended to go into the bios and turn off the Optimus setting. After I did this now it won't turn on. You'll hear it kick on and fans Rev up for a second and then it just sits there. F2 or nor F12 work and I'm just kind of at a loss.
BIOS may have been messed up. Try a manual reset as seen here; th-cam.com/video/76I2Ec9K7lw/w-d-xo.html
@@PC_Monkey Earlier in the day I had a suspicion it might have been the Quadro that failed. I quick pulled it apart and after pulling that out and retrying it without the GPU it did turn on. I do have another question though. I've read at GTX965M Type As are a direct drop in upgrade. Are GTX980M Type As also a direct drop in upgrade?
Great vid. I got a quick question. I have a dell 15 7548 where the internal display doesn't work. However, when it's hooked up to an extertnal monitor (by pressing the FN button), everything works fine. I've already checked the RAM, CMOS battery and change an entire screen assembly, but the problem persists. I've checked online and apparently there's some type of chip that needs to be re-soldered on the MB. I was wondering whether you can share an insight as to the potential cause of this before I go ahead with soldering. THX. Much appreciated.
Usually, if the computer displays fine to an external monitor but will not display to its own, the issue is with the computer's LCD or LCD Cable. Try replacing the cable first as its cheaper :) Then if that does not work, replace the LCD.
@@PC_Monkey I've replaced an entire screen assembly wich includes new screen & screen flex cable.

I have a G7. Great video. Step by step made it very easy. My laptop falls into the very first description. turns on, keyboard lights up, fans kick on, external monitor works. I did the LCD self test and the colors flash on my laptops screen, but still no picture. The webcam still works as well. still black screen. Pulled the ram. one at at time, no picture when one pulled. pulled the CMOS battery, still no. When I unplug the HDMI, the laptop even makes the noise indicating something was unplugged. Did windows key + p - The computer is thinking the screen is on (it does not show there is an external display plugged in - thinks it is the laptop screen). If I click on the toll bar bottom right corner, the laptop has 'wired display' lit up. help?
If the computer went through all those tests and no luck, and also if the computer is displaying fine to an external monitor, I would guess that there is an issue with your LCD or LCD Cable at this point. I would replace them one-at-a-time until you find the one that is faulty
Hi, my Latitude e5250 has this issue (black screen). It's not a ram issue because it I connect a monitor or tv it project's to monitor/tv. Is it possible to have a lcd/cable issue? I have tried unplug display cable from the motherboard and plug it again.. no luck. Any suggestions?
Yes. If your computer displays when hooked up to an external monitor, then I would try replacing the LCD Cable. If that does not solve your issue, then its most likely your LCD
I skipped the first few steps with the RAM and CMOS battery (sorry) and went right to plugging in an external monitor with a HDMI cable. Did not disconnect the LCD cable either. Display on the external monitor works perfect, and the laptop display is still really really faint. Do I still need to do the RAM and CMOS battery steps, or can I move ahead to the LCD cable replacement and/or LCD screen replacement?
No. You can go ahead and assume the issue is either a bad LCD or LCD Cable. I would reseat the cable at both ends just in case its just loose but if that fails, either it or the LCD may be bad.
Hi my laptop is dimly lit cause I still see its working when I use flashlight and direct it on the screen but I'm not sure if the problem is lcd cable of the screen and if there's anything I can do other than buying new lcd cable or screen coz am broke can u give me advice?

So is this the same issue & should I try the same fixes as you have suggested or something else will do ?
Thanks !!
Yes, its the same issue. Try the tests seen here :)
@@PC_Monkey thanks for replying & helping all of us with ur nice videos.
I have tried resetting RAM & that didn't fix. I guess CMOS could be the issue as my system is around 9 years old & whenever I restart the system instantly after the shutdown it works but whenever I try it after a day then it has this issue.
I will leave my system on charge tonight even after shutdown so that CMOS keep getting power, may be this will help in diagnose of CMOS issue.
Even according to this post www.hp.com/us-en/shop/tech-takes/what-is-cmos-battery-how-to-remove-and-replace:
The CMOS battery gets charged whenever your laptop is plugged in. It’s only when your laptop is unplugged that the battery loses charge. Most batteries will last 2 to 10 years from the date they’re manufactured. The more you leave your laptop plugged in, the longer your battery will last.
Here are the CMOS battery failure symptoms:
The laptop has difficult booting up etc.
Thanks again, really appreciate it :)
