Question about Gateway FPD2275W LCD Monitor
Monitor just turns on for a second then goes black......22" Gateway FPD2275W help??
Ok, I just got one last night, and it took a while to open the bugger. Why put screws when there are so many hidden clips to carefully pop? My poor Craftsman club card will never be the same! But, I digest...
There were two bad capacitors, the first and probably the main culprit was a 1000uF 25volt cap that had expanded and vented. I also found a 680uF 25volt cap that started to expand, and when tested it was low, about 550uF.
If you are so inclined, these can be obtained by mailorder (I use Parts Express), but Radio Shack parts can be used in a pinch, just expect to go back in there eventually. I didn't have the 105 degree low ESR caps, so I used regular ones and I had the monitor up and running in aobut 90 mins.
Check for any capacitors that are expanded at the top. Look for a dome shape or feel with your finger, it should be completely flat. Or look for the rubber bottom pushing out where it goes into the board. This is the third monitor I have repaired in the last six months, and each one needed one or two capacitors to fix a dark back-light problem.

Same problem, logo on powerup and a few seconds of display then BLACK. It takes a little work to get down to the power supply but I found the 1000uf @25v was bad, others looked fine. 45 cents worth of capacitor and an hours labor, were back on the road again.
Still like most of my projects, I have several extra screws left after assembly. Oh well, more for the jar.

Risetony is right with regards to checking the capacitors and replacing them.
If that doesn't fix the problem, its most likely an issue with the backlight itself. You may have to completely open up the panel and replace the defective backlight(s), but without a good way to test each backlight, I would suggest taking the monitor to someone with experience replacing backlights. If you see a display briefly, most likely one set of your backlights is fine. If one backlight is defective both sets will cut out after 1-2 seconds.

This is a common problem with many LCD monitors. The
printed circuit board that provides a stable voltage for the monitor to operate
from starts to fail. The PCB can be replaced, when/if they are available, or repaired
in most cases at a much lower cost. for more information on this email me at
