TC-P42ST30 power light blinks twice,replaced power supply board,no change.What to replace next?


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 ).

I have had a Hitachi 42" Plasma screen TV for almost 3 years and recently it has had problems. When you turn it on, the TV only stays on for about 10 minutes, and then the screen goes black with the...


The signal from the STU to the Hitachi box is going in the wrong direction.
Is the adaptor that you have switchable? If so, flick the switch in the
other direction and this will fix it. If the adaptor is not switchable get
one that is. Then set the STU output to RGB.

Hope this Helps. -CA

Soniq 42'' QSP424T keeps freezing


I have been repairing Plasma Tvs for some 3 years now and have found most of the problems caused are by Capacitors.Once again Soniq are no different to the others.The fault is on the main Video Control Pcb.Replace Capacitor C529 which is a 470mfd25v.This cap is mounted next to an inductor coil at the top middle of the pcb.This Pcb is the one which has the tuner and all inputs on it.
Good Luck AND PASS THE WORD AROUND. LET US KEEP THE SERVICE INDUSTRY GOING.

Magnavox Plasma HDTV Red light


I had a similar problem with my magnavox tv with the blinking light issue. Eventually it just didn't come one anymore. Looking at other forms they said the problem was a bad capacitor number 2074 located on the power supply board. When I opened my tv, I noticed that the capacitor was bulging and burnt up. I bought a new one labeled 2200uf 35v and did some solder to attach the new piece. Put the tv back together and it works like new. No more blinking light. I hope this helps.
