Question about Panasonic TC-P50G15 50 in. Plasma HDTV
Posted by Anonymous on
The 3-blink power light code on this model indicates a fault in the A-board (the one with all the input jacks) on the 3.3v line, according to the service manual for this model. The easy solution would be to replace that entire board (Panasonic part# TXN/A1FFUUS), however its somewhat difficult to find in stock now and when you do, it tends to be expensive. I have the same T.V. with the same problem. Currently, I am trying to isolate the exact board component responsible for the failure, but as of yet no luck on that. If I do find it, I'll post back with more information on what the problem was with mine. Meantime hopefully this at least helps you and others with the same issue to narrow the problem down a bit. :)

I fixed it myself!
I bit the bullet and ordered a replacement Power Board for AUS$290 and swapped it out myself.
Only took ten minutes, most of that time was removing and replacing the 101 screws holding the back panel on!
Working fine again now.
I did sit the two boards side by side and noticed the new one had moved some of the micro components from the back of the board to the front plus some other small component changes.
If your handy with a screw driver and have some technical knowhow I recommend having a go at fixing it yourself as it wasn't hard and probably saved $200 in service charges (all this assuming you are out of warranty!)

A very common problem with that model is the power supply board, if you remove the back you probably will find a couple of bulged electrolytic caps, that need replace, or just replace the power supply. You can check at www.partstore.com for a power supply.
