Hi, I bought a Vizio L32 HDTV10A that didn't power-up. There were charred components on the power board (an 8-pin IC with heatsink and 2 resistors). I replaced the power board, and the power LED then turned on (yellow) when power was applied. When the ON button is pressed, the power LED turns green for roughly 8 seconds and then the power LED turns yellow again. Nothing else happens. I checked many components (fuses, capacitor ESR, diodes, etc) on the main board and the master and slave inver

I have a Hitachi plasma model# 55hdt79 that went black out. No display at all. Sound is ok. We checked the power supply unit and found out that 90v output is missing. We changed the power supply unit assuming that this is the cause, but still the 90v is missing. All the LED lights on in sequence and switch off after loading when I switch on the main power switch. This means no error. The TV can be switch on and off by the remote. Which board is probably the cause of this issue?
