Panasonic TC-P50C2 Ten Blinks of Death

[mm6269]

Hello all. I have a Panasonic Plasma TC-P42C2 that stopped working. The unit displays only the 10 red blinks of death.

I have tried holding the power button for 10-20 seconds, dusting off/vacuuming the boards inside.

I have unplugged the SS board, turned it on, 10 blinks.

I have unplugged the SC board, turned it on, 10 blinks.

I have unplugged the SS and SC boards, turned it on, 10 blinks.

Any help on what I should do next would be helpful and appreciated

So is it 42 or 50 inch, you quote both? Try this, disconnect sc2(sn2), ss11, p35, 3 white ribbons at the A board, turn on and see if still 10 blink, don't run it more than 30sec, don't reconnect sc2,ss1,p35 straight away or residual voltages can damage boards or panel. leave for a while, 15min should be fine.
report back. If still 10, check SD card slot for foreign objects or damage, from there it'll be either p or A boards.

Sorry copy and paste error. I have the 50 inch. Okay so with all those disconnected, solid red light when I turn on the TV! Now what does that tell you lol. Thx for the help, much appreciated.

sounds like Sc board, although you had sc2 an ss11 disconnected, am I correct in saying you had SC20 ribbon still connected when you first started isolating and still had 10 blink?

Nope, I only disconnected the power connectors, no ribbons until you suggested I take out the 3 white ribbons on the main board.

So the answer is Yes, i still had ribbon connected at Sc20.

On that P5V and P15v are sent to the SC board from the A, so one of those is low ohms.

SC20 ribbon removed, at the Sc board

(next to Sc20)measure TP82 - gnd(also reverse probes for both readings Ohms)

Measure across C561(nearby) ( both directions) or TP16,17 - gnd for the 5V rail ( expect 5.6k ohms)

Ok so I'm breaking out my meter. I'm looking on the board for 2 points, TP82 and ground? With SC20 ribbon removed, all other cables in your earlier post are still unplugged? Sorry this is not my area of expertise

No prob, but it's fun learning. I knew SFA 2 years ago, now i can repair my own SC at component level.

You will also have to check the SD/Su for shorts before installing the new board, just in case or a bad buffer set can blow the new board. I'd do it before you send the SC off just in case they are expensive or unobtainable.
