I need help repairing an LG Plasma.
I've replace caps on the power board, one 400v270uf caps had gone bad on the primary side, both 250v220uf on secondary side. I measured the capacity but changing them didn't help.
Voltage is as it should be?
To YSUS
2xVS=193.6-193.8
2xVA=59.5
2xM5V=5V
To ZSUS
2xVS=193.6-193.8
2xVA=59.5
2xM5V=5V
CTRL
16.5=16.3
12=11.9
5V+5V_DET=5.0V
The part numbers are as following;
Powerboard: REV1.1 PSPU-J702A EAY39190301
YSUS-board: EBR50038901
ZSUS-board:EBR50044801
Symptoms;
I turn on the tv and the standby-light goes from red to green, blinks six times and goes solid green. I can hear a relay clicking once and there's a green light on CTRL-board. I've also checked the tv for blown fuses. Any help is highly appreciated. The screen is black.
