Hello, think i have similar problem as described higher. Screen backlight of my Asus M70v turns off after few seconds. I can turn it on again, but after few seconds it turns off again.. It’s 17″ screen and has a 2 light bulbs, so i think, one of them is gone. But I can’t find any CCFL for this model of notebook on eBay and any parameters of that bulb. Could i use CCFL from other notebook? I have 17″ HP (very very old) or 15,6″ DELL with died motherbouard..

HI. I have a acer v5 571 with flashing screen. I am now certain that the inverter. is bad. Guys at acer insist that I change the display panel which gives more money to them. Where can I get the inverter board for this. Any guesses?

Hi,
I have an Acer Aspire v5-571P and the screen is black when I start. Using a flashlight, I can see that the screen is working fine.
Couple of times, the screen worked well (I was able to see the pictures clearly) but after some time, the screen went black again.
I checked with Acer and the support person on phone said this might be a screen issue and it may come around 3000 NOK (350USD) to replace the screen.
pls help.

Thank you so much. Problem was with the sleep button. I could fix it. Thanks a lot. I have another problem with my laptop. 20% of the bottom of the screen is always flickering. what can I do to fix it. Is it the problem with graphic card? Or do I need to format my laptop? Please help me.

This site is quite informative. Keep up the good work. someone hit the screen of my Acer 4738z laptop since then screen has gone blank though it isn’t cracked. Each time I put it on the screen will flash and go dark and after some seconds it will flash again and stay dark indefinitely.I can’t see any image even with a flashlight. awaiting possible solution(s). tanx.

Hi there,

Any Hint?

I have a lenovo 3000 N100 the data on a screen is so faint, but when I connect with external screen It working fine, so I have change the inverter body the problem still continue, I have replace another cable and screen the problem still continues so I think the problem will be at the motherboard but I don’t know which part at the motherboard deals with the power to light up the back light, please help if you know something.
