Report "ILO p42bskh-us2 has standby power, powers on, but no sound or picture. there are two green leds on the mainboard. after about 1.5 seconds relay8001 on the mainboard visibly sparks, the relay(s?) click off, and led8001 turns from green to red. i've located the voltage values that should be tested for, but i'm not sure where to test as i can't locate ANY information on these sets. it has the samsung 42sd v3.1 common to norcent, tatung, and many other noname plasma panels. mainboard is samsung LJ44-00068A. there are no defective looking components in the entire set. thanks!"
