FAQ's:
Q: The computer displays to the external monitor fine but not to the computer screen.
A: If your computer displays to an external monitor but will not display to its own LCD, then your most likely looking at an LCD or LCD Cable issue. 'Reseat' the cable by unplugging it from the motherboard and the LCD. Then plug it back in to insure a proper connection. If that does not help, then replace the cable. If that does not help, replace the LCD.
Q: I tried all these tests but nothing helped and the computer wont even display to an external monitor.
A: If you have tried all these tests and have not been able to identify the issue, and the computer would not display to an external monitor, then your most likely looking at a motherboard issue. It should be replaced. Let me know if you would like any assistance with that process :) - วิทยาศาสตร์และเทคโนโลยี

I appreciate the simple and systematic way you explained the problem and possible solutions.
I had this problem of no display while computer was starting alright. I tried the solution of removing the RAM and putting them back firmly. It worked like a Charm. Thank you!

Thank you so much! Thought we needed to bin laptop and replace - your first idea worked! £20 on a new RAM stick and it's working! (hope it stays that way!) thank you!

Thanks, funny you should say that...! It worked fine all afternoon, then did a 'computer needs to do updates' message, said 'please do not switch off while doing updates' then shortly afterwards went blank again. Have done the usual (turned on and off, etc), no joy. Whirring, little light on, but screen just like before we replaced the ram stick... Has it got a fault that 'blows' ram sticks? Any ideas? Thanks!
@@bristolandyonderdid you ever figure out what it was?

My laptop screen suddenly stopped working but i used a hdmi and i see it working what can i do to fix this
@@kingvegeta6291 Your computer displays fine to the external monitor but not to its own? Then its most likely an issue with your LCD or LCD Cable. Replace the cable first as its cheaper :)
@@PC_Monkey i checked the lcd cable its fine but somehow theres no display
Thanks. Your video saved me time and also possibly money. Was a RAM issue for me. I took them out and reseated them. Started up fine again. Phew!! Appreciate your time to show us what to do

I have an unusual situation. In addition to not working (but obviously being on), whenever I plug an external monitor in, the laptop screen DOES work, but for less than a second before going back to black. If I unplug the monitor, it once again flashes and reverts to darkness.
Same thing for me smh
That’s me too!!!!
Same thing happened
Did you know the fix for this? I have the same issue. Maddening.
Afraid I do not know a fix still
I have a lenovo ideapad like the video with the same problem but I am able to get the screen to come on after restarting it. The screen only stays black whenever the laptop is shut and reopened later. Do you think I should proceed what you have done in this video?
So I got the Lenovo Ideapad 300-15isk. I took out the 4GB RAM, replaced it with another one (8GB) and got the black flickering screen. I put the original one back in and I still get the flickering screen (the original 4GB was working perfectly fine before. Just wanted to upgrade with 2 8GB RAM sticks). What do you think is the problem and what fixes do you suggest?
THANK YOU, my laptop is new and expensive so I was so worried but turns out one of the pieces was loose a bit and that's it, so thank you so much for this video

This is awesome! Thanks!
This fix works on the Lenovo Legion 5 Pro.
I realize I got this issue when I took out one RAM and plugged it back into the laptop. Maybe I need to re-seat both, before starting it up.

Ive went through all your videos to fix the problem of the screen not coming on.. let me say this.. I would start with the hdmi before taking anything apart. Once I plugged in the hdmi to test if the lcd was bad the lcd came on. Occasionaly it still black screens though and the hdmi jump starts it somehow. Any idea why?
I manage to get the Lenovo logo to start up, but it seems there’s still a black screen, should I do the battery method in your other videos?
Wow.Once you said the dim part, it is fixed. Thank you

First of all wow a very thorough guide + professional!
Ty the laptop started working but not sure what happened. I did everything but it didn't work; as soon as I plugged it in a spare monitor both monitor and laptop display started working.. confused about that but thanks!
Sometimes computers have issues and just need to be refreshed. Not a huge deal unless it happens again. In your case, it sounds like the just stopped sending the display signal and needed to be 'reminded' to do so with the addition of the external display. If that happens again, let me know. Glad your all set :)

Hi there, I have a Lenovo Thinkpad X1 Carbon. When I use the HDMI cable to an Acer monitor, the laptop keyboard and screen stop working. External monitor and external keyboard is the only way to use the laptop. I've had the mother board replaced twice and LCD screen replaced. It worked for a bit, then stopped. When i shut down and restart, the lights turn on the keyboard, the fan starts, i see a very faint "lenovo" startup image, but then i have to be plugged into external monitor in order to log in, etc. It's almost as if the HDMI or anything in displayport is confusing or frying the motherboard. Any ideas?
Your so underrated. Thank you so much 🙌🙌🔥🔥🔥

2 tips: 1. Replace "Lenovo" in your title with "Toshiba", since you're focussing on a Toshiba.. ;) 2. When plugging in your laptop to another screen, hit Windows key +P and then use the cursor down keys to switch to 'duplicate screen', 'extend', etc.. to see if you can get the other screen to come up. Thanks for the vid tho.. I'm hoping to check some things out on a Lenovo laptop within the next few days.
Win + p neither win+shift+control+b will work.
another tip.... my blacklight was dead apparently so to test that quickly put a flashlight to ur screen

My nearly new Lenovo Ideapad Gaming 3 had this exact issue. Powering on but nothing on the screen. I had added a second stick of ram and a bigger HDD. Removing the new stick of ram and re-seating it seems to have fixed my issue. Powered it back on and so far running sweet. Many thanks for this video, you have a new subscriber.

She only has 8 gigs of Ram, i’m going to upgrade it to 16gb = helps with system stability , etc ..... when you get into Bios look for advanced options / Repair tools, that’s we’re you can set it to factory settings.

Hello mate, I have a Lenovo y510p Laptop that's experiencing this problem. I actually tried 2 of your steps earlier this week, and just tried the 3rd step (using with external monitor / HDTV via HDMI cable), and no matter what step, the black screen still shows. The motherboard already got replaced from a local repair shop, so I don't think that or the RAM is the problem. I'm guessing it's either the LCD or LCD cable, because when I pressed Windows key + Ctrl + Shift + B, earlier it did bring up the whole screen, as if it's been working all along, but now it's reverted back to the black screen. Any ideas on what I should do?
Edit: Oh, forgot to mention, but the backlit keyboard no longer turns on as well (used to before motherboard was replaced)
OMG .. YOU'RE A LIFE SAVER .. MY SCREEN WORKS AGAIN ❤️❤️❤️❤️❤️❤️❤️

Wow I really appreciate how thorough you are in explaining things. I have this one question, my HP laptop stopped working a few years ago after we lost power one day and it was restored without a surge protector. I assumed it was junk and bought a new one.. recently I have a need for a second computer and I looked further into the old one. I first learned the LED codes of various lights.. With that info I learned the charger was bad, my new hp uses the same specification charger so I used that. Then the laptop would turn on, but no screen... so the caps lock LED blinks twice and I've read this is a BIOS issue.. Question being, do I need to reinstall the BIOS? Or could it be the battery, C Mos? OR whatever you called the battery for the BIOS lol Any help would be greatly appreciated
For a BIOS issue, I would first try a simple manual reset as seen here; th-cam.com/video/76I2Ec9K7lw/w-d-xo.html
If that fails to help, and the computer has been off for a while, its possible the CMOS battery is dead. I would then try replacing it. They are pretty cheap
@@PC_Monkey Thank for the reply, I will certainly support your channel with a thumbs up and subscribe.. if I need future assistance I sure know where to go!!! you're awesome!!

@@PC_Monkey Hi again... Hopefully you can give me some direction, I have replaced the CMOS battery in my HP 15-r131wm Still the same issue. I can hear the hard drive spin up when I push the power button but black screen... the cap lock light blinks twice, 2 long blinks then a pause and repeat.. supposedly this is a BIOS issue. Can I reinstall the BIOS with this situation? Thank you in advance for any insight..
@@scottsaint2122 Have you tried the other steps as well? RAM test and external monitor test?
Messing with BIOS is tricky and usually I dont like advising people on how to do it as you can easily brick the computer. To date, I dont have any BIOS flash or reload videos :( Sry
Hey so I have this problem where when I start the laptop it just lights up but it doesn't show anything, not even the logo and the loading screen. If I connect an HDMI cable to another monitor it shows only on the second display. So I'm not quite sure about the origin of the problem and if the video is about that.
If your computer displays to an external monitor but will not display to its own LCD, then your most likely looking at an LCD or LCD Cable issue. 'Reseat' the cable by unplugging it from the motherboard and the LCD. Then plug it back in to insure a proper connection. If that does not help, then replace the cable. If that does not help, replace the LCD.

Same issue
thanks for the explanations, i have a thinkpad t580 and i have replaced his broken LG full hd lcd panel with inolux one (done by a repair service) , it worked immediately but 10 days after the screen is completely black , i tested an external monitor and windows is displayed normaly via HDMI cable, so do you think that the new IPS panel died so quickely without any impact or bump or there is perhaps another problem that affect the panel?
Hard to say without examining it but yes, if your computer displays to an external monitor but not to its own, its usually an issue with the LCD or LCD Cable :(

I found out that if you close the lid, it is then going to send the signal to external monitor. But it might differ with each model. Great videos btw, very good explanations.

Hi there, great vid. I have a lenovo legion y740. The other day I was using it like normal and the screen went black out of nowhere. By looking very closely I can see that the screen isnt actually completely black, but it is so dim you pretty much cant see or do anything. However it is still functioning and I can plug it into a monitor and use it like normal. It's less than a year old and still under warranty, so I am hesitant to start taking it apart myself. If it is working with an external monitor, should I still check the RAM? Or is that useless given the fact it is working with an external monitor? What do you suggest?
If its working with the external, than your right, its mostly not the RAM. Its most likely the LCD or the LCD Cable.
Just bought a HP desktop and the screen is really dim not so bright! Any recommendations????
Dim like you cant see anything or just dimmer than you would like but still usable?
use hdmi cable it will show clearly mine was doing the same until i got hdmi cable and now showing clearly...
God bless u , it works well

This video is for a computer that turns on but the screen is not working. Is that your issue? If the fan is not starting and the screen is black, what are the signs that your computer is on?
your mixing all together what you trynna say, so can the dim screen aka backlight not working really be a ram issue or not? cause i dont quite understand what you trying to say dude. cause ram is working i think i have just one bar and the computer works just fine just dim screen. and i already replaced the screen cause the old one broke there was comming light trough the broken old screen but only 1 times and after that ive never seen it light up, i also change the cable and tryed with a new screen and still no light. i have iadepad 310 and have heard some laptops have an lcd backlight fuse, but i cant locate it myself on the board, everything i measuerd with ohm meter was ok

Sir, would it not make sense to check the ccfl first with a flashlight? Thats what I'd wrong with my sl510.
Yes, you can do that to see if the screen is just dim. I can usually tell without the use of a flashlight
Will you do all the same troubleshot if when the laptop is connected to a monitor, the system works properly. I am asking because I saw a Lenovo laptop where the screen is very dark, it can be hardly seen, I have to put a flashlight in front of the screen to see that there is actually something in the screen. My first instinct was to connect it to a external monitor, and when I did the image in the monitor looks perfect no issues. At least to me this indicates that the problem is in the screen. Am I missing anything?
You are correct :) Nice job !! Yes, if the external monitor works fine, then the issue is most likely your LCD or LCD Cable. Try replacing the cable first as its cheaper.

My Lenovo laptop is having same issues.
I can't go to boot or no lenovo logo showing. But then I checked in another monitor it was working. Maybe the display wire problem.
But the screen was turning on after half an hour but no logo anything. Just black screen. Can it be the display or display wire because it's loading in another screen and HDD fan Ram all okay...I thought it's may be CMOS battery.
So your computer will display to an external monitor but even with that external monitor it will still shut off after 30 minutes with the computer still being on?
CMOS batteries can be tested using a mulimeter set on DC voltage. Generally, the batteries should test at a little above 3 volts DC. They will still work a little below 3 volts, but I replace them if they are below that threshold.
Why would the laptop not start without a CMOS battery though? It should start up just fine. It will just start with default CMOS settings.
Hello, I'm using Lenovo L490 i5 and I'm got Blackscreen after Hibernate/Sleep all of a sudden I tried looking for solutions but ended up pressing power button for 30 seconds to force restart but now even if I press Windows + Ctrl + Shift + B or Ctrl + Alt + Delete/Ctrl + Shift + Escape there's nothing happening I don't know what to do now since I can't tell if Thinkpad is still responsive.
Btw keyboard presses still work I'm trying out FN key + F1-F12 buttons and indicator still works
1. Are there any signs of life at all when you try to turn it on? Lights? Fan, Motherboard, or Hard Drive sounds? Anything seen on the screen?
2. For a computer that does not turn on, try this video first; th-cam.com/video/HHwzA37r4e8/w-d-xo.html. Let me know how that goes :)
I took 1 of my ram cards out and it started working then I put it back in it didn’t work then I swapped the positions of the 2 ram cards and it started working????
Glad your all set :) Perhaps they just needed to be reseated :)
I have a Lenovo flex 14api, screen went SUPER DARK to where I know something is ther but not at all visible or useable. I've updated drivers, did factory reset, pushed all the sequences of buttons. When I connect to external screen, computer works great, even laptop touchscreen actions visible on external screen. Any clue what's the fix?
If all the update and reset fixes didnt help, your most likely looking at an issue with your LCD or LCD Cable. Try 'reseating' the cable at both ends. If that does not help, then replace the cable and the LCD one at a time till you find the one with the issue :)
