Re: Panasonic TC-P50G25 4 Blinks

That did the trick. Hopefully it holds for awhile. Thanks again for all the help!

Re: Panasonic TC-P50G25 4 Blinks



Will do. Where is Q661 located? Tried to look last night, but I did not find it. Thanks again for the help. I will follow up when I get a new board....

Re: Panasonic TC-P50G25 4 Blinks



Certainly saw that myself. It seems to be a Marketplace similar to Amazaon. The P-board I bought clearly said it was New. This one, not so much. So, if I can return the P-board, I will probably just buy this one for $10 more from Encompass. They all seem to want the core back, however. Encompass even charges a core fee until you return it....

Re: Panasonic TC-P50G25 4 Blinks



I am not very handy with soldering, so I am not even making that an option.

Looks like that one is Out of Stock. Panasonic (through Encompass) has one for $170. I also found one (from the same place I erroneously purchased the P board) on Sears Marketplace from TVReplacementParts for $160. I will probably see if they will swap out what I got for that one and just go with it.

Anything to be aware of when hooking it up? Just make sure power is out of TV, install, and test?...

Re: Panasonic TC-P50G25 4 Blinks



Thanks again. Here's what I see. My multimeter only goes to 3.999 Megaohms
1. Unplugged SC2, power on TV, 7 blinks, so that looks promising.
2. Followed instructions for resistance testing of SU-SD boards (P. 43-44). Removed connectors and screws.
- TPSU15: 1.285 M ohms (lower than sheet says)
- TPSU16: 219.4 K ohms
- TPSU17: 3.999+ M ohms (still rising to top of range of meter, so that one is probably good)
- TPSD26: 3.999+ M ohms (still rising to top of range of meter, so that one is probably good)...

Re: Panasonic TC-P50G25 4 Blinks



Thanks, TW. I will try removing SC2 tonight to see if blinks go away. For the Sd/Su checks, do I just need to check the steps on 43-44? I can report that back this evening as well....

Okay, I have perused through several threads on this. I have also done troubleshooting with the 2010_FHD_Plasma_TV_G20_G25_Series_Troubleshooting_Handbook.

I was originally getting 10 blinks, but now it is consistently 4. I troubleshot the Vsus, P15, and Vda. Vsus and P15 look great and always show resistance of >1.5 kohms. Vda actually bounces around a bit, but shows even in the M ohms range. I thought that might be my problem.

I even ordered a new P board, but it shows the same type readings, and it did not fix the problem. So I continued the 4 blink troubleshooting...
