First real post here. I was thinking about recapping this but figure I would check in here first since there's no evidence of the caps busting (yet).
I tried to read as many threads as I could about the 2 sec then off problem so I started checking a few basics. Power supply board is FSP055-2PI02A. All the electrolytics on the board I can read are TAICON HW and HH series except for 2 CapXon KFs on the low voltage outputs.
Symptoms are power up, power light goes from amber to green and stays on green and steady. Back light comes on, see the ACER logo, then within a second or two the backlight dims slightly and then goes off completely. Since this is a four back light system I'm guessing I'm losing one of the pairs then the other.
The low voltage power outs to the input board from the PS board are just +5, +12, back light on/off and ground.
+5 is right on +5.0
+12 is between +13.5 and +14 which seems a little too high to me, but maybe without the back lights running its different than it should be under a properly loaded condition?
What can I look at next? I'm guessing it's time to start taking the panel apart and check out the CCFLs :\ Thanks for any help ahead of time!
