Hello,
How to isolate the sections for display problems in laptops? There are LCD panel, Inverters, external VGA ports, and a section between VGA port and LCD Panel ( I don't know the technical term for it). Any suggestion on procedures to follow while fault finding will be greatly appreciated.
Thank You

Hello rtantri;
When you shine a light on the dark LCD screen can you make out anything on the screen?
If so the problem is likely the backlight tube or the inverter.
Had you tried to hook up an external monitor?

Thank you WR2 for your reply

I was asking a general question not any perticular Laptop. I come across a quiet a lot of them with similar symptoms, where there is display from VGA out port, and dark screen but faint display in the background, indicating a inverter problem. But many at times even after replacing the inverter module the problem persists. This is where I need some tips on solving the problem. If you can help me I will be greatful

Thanks again for your prompt reply. Sorry I could not reply earlier.
