My laptop screen keeps turning off (inverter or backlight)
Last response: in Laptops & Notebooks
So, I am having an Acer aspire 5334 laptop, and suddenly my screen went black. i checked 100 of forums, and result is:
External monitor works fine so its not the graphic card,
when i turn laptop on, it works minute or two, but then it turns off. when i look into screen with flaslight i can see dim image, so i suppose it is the inverter, or the backlight. as the backlight itself has 50.000 hours of life, i assume it is the inverter problem. And another thing. when i have external monitor connected to laptop and i switch between internal and external monitor, internal turns on again, and works for few seconds, then goes dim again. I also tried changing the settings (when u close the tray - do nothing, etc., that didnt work) before i go into buying new inverter.. is it possible that it is a software problem, and should i try formatting the computer?
and one more question. i have one inverter at home. but its Medion, not acer. and they also look different. Should i try putting medion's inverter in acer's laptop, or it is not a wise thing to do?
please help a.s.a.p.!

More about : laptop screen turning inverter backlight
I've done a few strange things with laptops over the years but I haven't attempted that. I will recommend against attempting it without a schematic for the screen and inverter (if you do try it without a schematic, be sure to video the results - could be fun)
I will highly recommend getting the proper inverter for the screen here

well, i dont think i need schematics for the screen, cuz i disassembled few laptops so far, and i know how to do it. i did disassemble my acer yesterday to check the cable connections on inverter and video cable.. it didnt help. tomorrow im gonna try to format laptop. if that wont work im going for the inverter.
It sounds like an issue with the backlight.
I have experienced the same issue in the pasted were, there are 2 backlights. When one of the back lights fail, the inverter shuts off as there is no longer equal load on the inverter. When you toggle between the different screen the inverter tries again.
To resolve the problem replace the panel or be brave and try to replace the bulb.

Hi there
before buying the inverter just a question for you. U say it goes on and switch off after a minute or 2 right. does your Laptop heat up fast when you switch it on ? if it does make sure your fan is clean and running well. a dirty fan can course over heat on your board/CPU and make your screen go black. hope you get your problem solved.
