Re: 55 inch Plasma Viera (VIERA TC-P55GT30) not turning on. 7 blinking red lights.

Hello group,

I have the TCP50GT30, which should be close to same unit, also with 7 blinks. The SC was shorted across SC20. I replaced all six transistors (3 were shorted) but still 7 blinks and SC20 looked shorted again. I sent SC out to a board repair service but want to be extra careful when it comes back. I will isolate from SU and SD by disconnecting and using the jumper as per the manual as a preliminary check that SC is now good. But how do I check the SU and SD without risk of...

Re: Panasonic Plasma TC-P50GT30 7 blinks SC board shorted

After an unsuccessful attempt to fix 7 blinks by changing out the 6 transitors on my SC board (some of the new ones shorted too) I sent my SC board out for repair. I intended to isolate the SD and SU boards as described in this forum when it comes back to be sure the repaired SC board is good. But how to I determine if the SD and SU boards are bad. I saw a reference to some resistance tests but the values were not for my model (tcp50gt30). Does anyone have SU41 and SU42 values for a tcp50gt30 to post? I don't want something...
