Panasonic TC-P50X5 Plasma TV Dead

[Ltank]

The TV is strange. The Power Supply and the SS board are one board. The cable from the
P.S. to the main board is one of those metal wire type. No markings
on the board for pin assignments. Power Supply. NOAE6J00006. Are any schematics available? Connector pin assignments? Any help is appreciated.
Thanks

Do I Jumper JP67 STBY 5V to JP64 Main_On? I have the STBY 5v (4.98) and I Had 165 VDC across the main filter cap. The SMD part numbers are not legable even with a bright
magnifier. No Blink Code. What is the Blink Code for this set?

I have the exact same board as you but mine keeps blowing out new parts! My TV is a TX-50X50B but the metal connects are exactly the same as yours. I believe the connector pins to the AV board are the same.

I'm unable to locate a service manual for yours but I have attached one for TX-50X50B which you could use as a reference. The connectors could be found on page S8, which has the schematics for the pins on the AV board joining to the PSS board.

I know it's not your model, but I hope this is better than nothing...

Well, I finally got back to this TV. I jumpered the STBY 5vdc to PS_On
with a 470 ohm resistor (4vdc) and the power suppy turned on giving me all the correct voltages. With that I am sure that the TNPH1001 main board is not giving the PS_On command. I did not see the voltage on the PS coming back from the Main board. I will replacethe main board

I have the same TV and have no standby voltage. I do have 135v at the filter cap, but when the power button is pushed nothing happens, there is no clicking sound when plugged in or the power button is pushed. I can't seem to find a service manual for it so I hope someone can help

Wow!

About 9 months ago this Panasonic TC-P5x05 was thrown out by a neighbor and sat outside for trash pickup until the old lady next door snatched it and dragged it into her apartment.

A month later it was setting back outside for trash pickup, so I dragged it in and set it on my desk. Plugged it in. no signs of life - no idiot lights, no sound, nothing. I had looked online and found some known issue with power supply components, so it sat for 9 months.

Today I invest 3 hours time looking for the info again, join this site, doing research, then I decide to plug it in and it powers up and runs like nothing was ever wrong!


WOW - So this television is FEMALE

I have a feeling it's the standby IC that's dud on this series. Did you find the other threads on the part number and suggested replacement to fix?
