Are you SURE you get 2 blinks? I show NO 2 blink code in the 011 model Pana plasma sets. Anyway...if you replaced the PS board and still get a code, unload the VS supply from the SC board and re-check--see if the VS supply comes up--even for a couple of seconds...about 205 volts or so. If it does--re-connect and see if it then does not come up. If not--then the SC board is likely bad (THE most common failure on ANY plasma set is the Scan board ).

SOURCE: is it hard to change power supply board on

the critic about microelectronics is the fragile that can be manage the boards specially the connectors and really specially some fiber optics this tv has, The main problem is that you probability is high to be surprised when they are already broken because you didn't know where they were located. think about it and probably getting and estimate is not bad specially if the tv only has that problem.

SOURCE: replaced convergence ics but now power light blinks 3 times

Your model will not work with STK392-115 in fact I have never heard of those ICs.

SOURCE: replaced convergence chips, have new problem

Did you check the 2.2 ohm 2watt resistors? As often one or two will blow when the old ICs fail. The 3 blink error is indicating a problem with the convergence circuit still.

SOURCE: just replaced lamp. when plugged in, power light

km, I'm having the exact same problem,...lamp housing is secure and so are all covers. From my research the power button will flash yellow when the covers are not secure. This is not my first time at replacing the lamp,...but now, after replacement, powers green flashing, then red flashing, followed by lamp flash red every 5 seconds,...research continues.................
