My Laptop Screen won't turn on upon start up

[bulldog43]

Hi there,

I have tried it, firstly pictures came out on both screens, on  notebook and CRT, but screen size was smaller on notebook, then rebooted, and this time notebook screen was black while CRT still got picture on, so that means video card dead then as you said, now I need to buy new one, is it easy to fix it, never opened inside before,

And I just ask you something, when notebook picture was  smaller,  I tried to change resolution because a message appared on the screen saying something about optimal resolution anyway, and I think I put the resolution 1600x..., but afterwards I put the system back to save the earlier resolution, but I am not sure, did it go to earlier one or stayed same, do you think is it possible to change the resolution again, if it hasn't been changed during system back,

Thanks again, it has been a great help

Good morning bulldog43.

So the video card will output to an external monitor (and make the LCD work in the process) as well as works in Safe Mode.  To me this implies that it still has the chance of being a software issue because the card appears to work in certain situations.  It is possible that this is a hardware issue but I would like you to try one more thing for me to rule that out.  

I would like you to perform a System Recovery.  This resets your notebook back to factory conditions.  This is a known working state so it will rule out software issues with a high degree of certainty.  However, you WILL lose any data which you do not back up.  So, if you have important files please save them on an external device.  This document covers the recovery process.  

Let me know the result of this.  I really appreciate your patience.

Hi there,

I have done it, you were right it was hardware issue, after doing system recovery to make it back to factory conditions.

Notebook screen works fine now, thank you very much again for all your help,

All the Best,

same problem. i have hp pavilion dv2990nr. when i turn it on, the lights turn on, i could hear it starts but the screen is very dim. it happens a lot, but sometimes my laptop starts normally with its screen also normal. what could be the problem?

[t4v05h]

I have the same problem with my screen, I turn my computer on and everything starts but the screen.

I have tried to take out the battery and press the start up button for 15 seconds, it worked, but I have to do it every time and sometimes for 3 or 4 times until it works.

My laptop is a HP Pavilion g4-1287la

Please, tell me what to do.  I have read that there are some others with the same problem and with g4 laptop.

Hello T4v05h,

I understand you are stating when you turn on your computer you receive no image on the screen, is that correct? I will be more than happy to help you.

Your computer comes with an HDMI and VGA connection, I would like you to use either one and try to plug your computer into an external monitor or TV either or is fine. When you turn the computer on seeing if you receive an image, if the first time doesn’t show anything try it at least 2 more times.

Please respond back at your earliest convenience.

Thanks

RedRose,

I have the same problem as T4v05h and followed your instructions by plugging my laptop into a tv via hdmi cable.

The screen shows up on my tv. So what does this mean / what do I need to do to get the screen on my laptop working?

[RedRose0528]

Alex-S,

That tells us the video card is functioning correctly. Looks like the issue could be the monitor itself, inverter or maybe a bad cable connection from the monitor to the motherboard.

Do you know if the computer is still covered by warranty, if you aren’t sure insert your serial number into this link  The serial number can be found on the bottom or you may have to remove the battery and look inside of the computer.

Please respond back at your earliest convenience.

Thanks

I have tried what you told me, and had the same result as Alex-S.  The image displays in the monitor that I connected, but the monitor of my laptop is black.

I checked if the warranty is still available in the link that you sent to Alex-S, and it is still available. 

What should I do now?

Thank you in advance.
