Fooling the inverter board
Could someone know how to fool the inverter part of the board to think the ccfl is connected (when ccfl is dead and i dont have spares) i know i can use 200kohm 5w resistor on the terminals but i was thinking of something more elegant, that wont suck power and still give it a feeling that lamps are ok?

could the RED lava be the light from lamp(s) being red? if so ...

i used to use Nichicon caps but then customers stoped bringing their lcds for repair however i never fixed lcd over 24", never had a chance, but this sounds like an average day caps problem ... IF the plasma stays ON after ~30 min of warming up.

i agree but problems like what you listed arent common, samsung, LG, asus, all of them are same inside, same chinese shizz... caps, CCFL, inverter, mosfet are 4 most common parts that die in ANY today lcd, plasma, led screen... since plasma is 42" its really big, has more ccfl's draws way more juice, parts heat up faster, last shorter, especially caps, capxcon being one of the shizziest caps ever...Leave a comment:

hairdryer blows hot air all over the board, soldering iron heats up a specific spot, it will boil if you keep the iron for too long, logicaly, my father is an electrotehnician for over 30 years, me too with him... plasma tv starts working normaly after 30 min (?), that is a bad cap, its capacity slightly increases with temperature, after some HAPPY HOUR time of about 15 to 20 days that cap drys out or blows. my guess thats one or few of the caps closest to the heatsink.Leave a comment:

you have bad caps, take soldering iron if you have one and heat caps one by one, starting with 4 big caps on the middle board near to the heat sink with 8 transistors, see if tv lights up. heat caps until u almost cant put your finger on them, place the tip of soldering iron on the top metal part of the cap, ofcourse.Leave a comment:
