Panasonic Plasma TC-P50U50 8 blinks SS board fix

[Sevenqi]

I got this TV with 8 blinks, searched this forum, this is a comon issue with this model, the SS board problem due to the bad contact with the ground in the panel.

Open the cover and checked the SS board, 3 parts were damaged: D16041(RF2001), Q16051(DG302) and R16051 (5.6 Ohm resistor).

Take out the board and found there were arcing marks in the panel, and the SS board as well.

Cleaned all thoese arcing marks.

The RF2001 is easy to find in the old plasma board, I have other board which has 5.6Ohm resistor and a DG302, but its package is different.

Replaced the RF2001 and the 5.6Ohm resister

To the DG302, what I did was to desolder the headsink, made a good area on the pcb board for the DG302 as heatsink, soldered it to the PCB board.

Put the board back, it works perfect.

One more thing I did to this TV: I found the heatsinks on the SC board were very hot after a while, so I added a computer CPU fan near the SC board, I hope this can make its' life longer.

I just repaired one. Got a kit from Shop Jimmy.I did not use all the parts. 20 bucks plus shipping. I used Q16051(DG302) and R16051 (5.6 Ohm resistor). DG302 was shorted across all three legs and it burnt open the smd reisitor. The other parts were fine. Sets woorks good again. The kit was not too bad because people wanted 9 bucks for DG302 alone. I could not find the 8 pin IC anywhere so I bought the kit. I was able to find a PDF on the IC and checked it for shorts and it checked good. The Drain is soldered underneath and can cause damage to board if removed. I did not want to chance it because it did not seem to be shorted.

The DG302 I had was bad was the one mounted to the heatsink not the one on the board that uou have pictured

I also got the kit from shop jimmy and went ahead and replaced D041 and Q051. D041 ckecked good after removal but Q051 was shorted. R051 checked the same as the new one in the kit so I left it alone as well as IC152.

TV fired up, no blinks. We will see. This Forum rocks!
