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

Thanks for the info. IC seems to be very difficult to source. SJ has parts for my sc so this may be the easier. MOSFETS can be purchased alone. Shame considering how good the picture is. Sad state of affairs in home entertainment.

Had same 7 blinks of death. Followed the advice of those in the know. Many thanks. SC2 showed a short. Found Q401,402 and 403 obviously shorted. Replaced. Still have same 7 blinks. Again, these IGBT bad. Diagrams unhelpful. Traced and found Q421,422,423 opposite side of circuit through coils at top of board. If one or more are shorted they did not show short at sc2. To be safe and while you are there best to replace all 6. Not sure about the resistors, IC and small driver.

Beside the...

Thanks soooo much for the info. I have a 50st30 with the dreaded 7 blinks. If possible I will try the component replacement on the SC board. My question is regarding the removal and soldering of the IGBT's. Has anyone had success and with what tools? Thanks

Hi! My name is James (zoiman). I am retired and over 60 yrs of youth-or so I think. I had a career in the military(USAF) as a biomedical eng. and have interest in technical areas. I have over that time learned many skills that I no longer practice or can afford but still return when I can. My problems with consumer electronic devices(TV esp.) brought me to this site. So far the general info has been helpful. I look forward to more.
