just picked up this TV tonight. Blinking 8 times. Looked into the SS bored and found shorted Q051. DG302 mosfet. my understanding is there are a few discreet semi conductors on this board that go south along with the shorted MOSFET. I have yet to find any other short circuits on any components. I wonder if I just replace this DG 302. Does anybody know a good substitute. I don't feel like spending 50 bucks on eBay for a repair kit for this board. I have another Panasonic sustain board that uses a few different mosfets. they fall just a tad short of the specifications of this mosfet. anyone with experience on this board could you tell me what else I should look for in the way of other failed components. it appears to be a common failure on this SS board. Thanks
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: panasonic TC-P50U50 8 blinks
Personally I doubt it. They had that issue with their 2010 & 2011 panels. They've had more than sufficient time to sort it out, if it did cause it, that's poor design. I'm going to hug my PZ80, because it looks like there are no good plasmas made beyond about 2011.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

The 2006 SD I gave to my mate is still going after that simple LVDS reseat and he loves it.

Oh yes top screw was loose.Did I leave the soldering iron on?

Personally, I have the 50G20 equivalent 2010. My 2009 HD has better contrast, and i have a 46 PZ800 and it's definitely sharper. The FHD 2010 model is washed out a bit and dimmer, also has better power consumption and that's probably why as i believe they've concentratedd on reducing power consumption, Just my 2 cents worth.

Re: panasonic TC-P50U50 8 blinks
my two cents worth is the less components on each board and the more confined that these TVs have to be lately the worse picture quality. On a side note it appears that the tc-p55ut50 inch uses the same SS board so I already have the board go figure. Oh and the top screw was loose on this one just like my 50 with the shorted SS. Maybe the panel is beind used for some kind of "last resort" heat sync and if the screw loosens the SS cant cool the top mosfets?Did I leave the soldering iron on?

Re: panasonic TC-P50U50 8 blinks
Good evening. I stumbled across this site & thread because I also have a TC-P50U50 with 8 blinks. I'm a copier tech, so I'm not as savvy with TV's as some of you may be. I know 8 blinks can indicate a number of issues. Since I have low experience, I want to just buy & replace the SS Board because it seems like the most likely culprit.
I was wondering if there was any alternate suggestions or if anyone knew of the best place to buy this board. Seems like the only place I can find one is ebay. Thanks for your help!
