| The "Guest" reply before this one was mine, too...I wan't logged in, apparently. This TV is FIXED and ready for the kids to enjoy over the holidays! I replaced the A-board and it is now working. With the large electrolytics on the power supply boards, too, this one should hopefully serve my family for a long time to come. |

| Thanks for the reply. It isn't in the warranty period anymore. I've fixed other sets before, so I'm giving it a go with this one. | |

| My advice would be you should take it to the dealer..if it is in its warranty period he will replace it and your kids would be able to watch tv by Christmas. Merry Christmas and hope it helps |

| After some more information gathering and measuring of outputs from the power supply boards, I'm ording up a replacement A-board and will roll-the-dice with that. Should have further results by week's end. | |

|
| Make: Panasonic Model: TC-P65S1 Description: 65" Plasma, Manf. Jan-2010 The TV did not power on anymore. After pressing the power button on the unit, there would be a first relay click, then a second (and the cooling fans would start spinning). A second later there would be another relay click (the fans turn off) and a last click and then the front power LED begins blinking steady (1s on, 3s off). I replaced the stressed large 'lytics on the MULTI and SUS power boards (3X - 350uF 450V, and 3X - 1200uF 220V). The replacement caps are 390uF 450V, and 1200uF 250V - new Nichicon parts rated, like the originals, at 105C. After replacing those stressed 'lytics, I am still getting the same behavior (power up, then off, and the steady, 1-blink LED). I see no signs that the screen is powering up (I'm more familiar with LCD sets, than plasma, but there's no action on the screen during this power up/down process). I have the service manual for the unit, and am familiar with electronics repair and troubleshooting. The service manual provides no guidance for a steady 1-blink state...it seems to be the universal "you're screwed" indicator  The only measurement I've taken so far was to see that (between test points TP5 and TP6 on the SUS power board), the Vsus rail climbs to about 185V before the shut-off. Any help is appreciated...I'd like to get this running for the kids to enjoy at Christmas. |
