Re: Panasonic TC-P55VT60 7 Blinks. Need Advice
I have the exact same problem mine is a TC-P50ST60, picked it up for free to fix.. did all the trouble shooting and replaced the SU,SD,SC boards as suggested in the repair manual. Also checked for short at sc2, sc20, and Vsus.... Let me know if you find anything? I'll be keeping an eye on this thread looking forward to see if you can get yours repaired.Leave a comment:

Re: Panasonic Th-42pz700u 7 blinks.
How did you test the transistors? I believe those are MOSFETs not sure if you can test them with just a multimeter. I tried by placing negative probe on Emulator and Positive to Gate (apparently any reading would mean its faulty) could someone here please explain a way to test these MOSFETs with a just a multimeter?...Last edited by alexeilb89; 08-04-2016, 10:45 PM.Leave a comment:

Re: Panasonic TC-P50ST60 repair
After removing the Bluetooth module tv still doesn't work, same 7 lights. I am wondering if something on the A board is causing this or is it really the Bluetooth module, is this something common or known??...
I measured the voltage with the SC board connected, I should be getting around 3 volts right?
as far as the 3.3v is concerned, perhaps has something to do with my set not working, hope its not the panel that's causing all this nonsense. Again thanks for the info, I'll keep digging....Last edited by alexeilb89; 08-04-2016, 11:51 AM.Leave a comment:

Re: Panasonic TC-P50ST60 repair
At this point I was able to trace the problem down to the Bluetooth module, if I unplug it I get no short at P3.3C, does anyone here have any answers?Leave a comment:

Re: Panasonic TC-P50ST60 repair
I just removed the ribbons that connect the C2 and C3 drivers to the A board and P3.3V is no longer short.....Last edited by alexeilb89; 08-03-2016, 05:12 PM.Leave a comment:

Re: Panasonic TC-P50ST60 repair
Thanks for the reply, I appreciate this information.
I am not sure how to check Va and Vs voltage and where I would locate those test points. I checked the ss board TpVsus (no short), Vsus (no short), p5v (no short), p15v (no short), however checking the Data Drivers C1,C2,C3 VDA shows no short, but all three p3.3v shows as short. Not sure if I am testing these wrong, every single one of these test points has an arrow labeled with (SRV).
After removing sc2 and sc20 the...Leave a comment:

Panasonic TC-P50ST60 repair
Hello everyone,
This will be my first post on this board, wanted to make sure I do all the research first and read previous posts as there are a ton of threads regarding the 7 red lights of death before I post anything on here, I am just totally at lost at this point and feel like I've tried everything.
Bought used parts from Ebay that claimed are working and replaced the SU,SD,SC and still got the 7 lights. I isolated the SC board from SU and SD as instructed in the repair manual and received the 7 lights. Checked resistance at SC2 across both pins (no short),... -
Re: New Members - please post your introductions here
Hello Everyone,
I joined this community in hopes to fix my Panasonic TC-P50ST60: 50 inch TV (7 red lights of death). I have no electronics background, in fact last time I fixed a TV included a trip to Wall-Mart at 3am to purchase baby oil, a turkey baser, and some tubing... It was an old 65" Mitsubishi Rear Projection TV, believe it or not it actually worked. Anyways, I'll be making a thread about my Panasonic shortly, just wanted to say hello.
The turkey baser was used to extract...Leave a comment:
