Having problems with your Sceptre X7GNAGAV 17" LCD Monitor ?

My display on the lcd monitor goes blank after startup.

\015 I GET A DISPLAY FOR ABOUT 30 SECONDS AND IT BLANKS OUT.\015

Answers :

It sounds like a backlight problem. It could be a problem with the inverter board or backlight itself. When the display "blanks out," can you still see a faint image on the screen -- especially if you look at an angle with some light shining on the screen? It is usually easiest to see changes on the screen - so after Windows boots, press the windows key on the keyboard repeatedly and look at the part of the screen where the start menu would appear. If you can see anyting, then it is definitely a backlight problem.

If it is a backlight problem, you'll need to disassemble the LCD panel to correct it. Correcting it might be as simple as re-seating or re-routing a loose or pinched backlight cable to as complex as replacing the LCD panel and inverter board. There is really no way to tell over the Internet. You'll probably void any applicable warranty by disassembling the panel.

By the way -- watch out, the inverter board can generate lots of voltage and reasonible amounts of current. I've never been shocked by one, but I've been careful.
