Question about LG 32LC2D Television
Yesterday morning the set was working fine. Left for work, and when I came home the set would not turn on. I unplugged it for a while to see if it would reset itself. Nothing. When I try to turn it on, or even when it is plugged in for that matter, the power light in the bottom right corner just blinks green/red/green/red/green. I was thinking maybe a fuse but I could use any help availabe. Thanks!!

Solved - Blinking and shut-off problem, also buzzing sound....
I replaced all these capacitors. Make sure your capacitors are 105 degree Celsius. Because I saw 2 pcs. had 125 degree Celsius which in fact my first time to see this rating. The 105 will work fine but discourage using the 85 degree Celsius.
2 pcs. 1000uf 35V
4 pcs. 1000uf 25v
2 pcs. 3300uf 10v
2 pcs. 470uf 10v
1 pc. 680uf 10v
1 pc. 1000uf 16v
Note: You have to replace all of these capacitors regardless some look good. Because some / few failed under load test. They passed my capacitor tested but actually defective when the power supply board was connected.
Second, don't forget to clean the back of the board by toothbrushing it by 91% alcohol.
Third, resoldered all transformers legs, inductors, and the 4 mosfets.
