Ipm is "new" ? Where did you get it ? Most are pulls at this late stage of the game.

t-com fault ??

mmartell yes new ipm never solderered possible to found it

thank for your help

[ReeceyBurger123]

Re: Plasma LG 42PC3RA led blinking

Does sound like Tcon fault

[mmartell]

Re: Plasma LG 42PC3RA led blinking

Cheap enough to replace it (at least here) but something tells me it's not the problem. Without the control board ribbon plugged in the ysus isn't asked to do much so very possible to see Vs until it's asked to create a waveform. Still think you have ysus problem.

Re: Plasma LG 42PC3RA led blinking

Not a Zsus issue, have you tried adjusting the Panel voltages ? Also you might need to update the firmware on the control board.
