Re: Panasonic P65GT50
I disconnected the main board and power supply from every other board except each other and I do not get the 8 blink code. I can keep everything plugged in except the ribbon connection between SS board and A board (SS33/A33) and I do not get the 8 blink code. Once that connection is made, I get the 8 blink code. Once the logic level on TPS0S8 goes high to 5V, that triggers the 8 blink event. Should I just try replacing the SS board?

Re: Panasonic P65GT50
Anyone have any suggestions or can anyone tell me where I can find some parts for this old plasma?Leave a comment:

Panasonic P65GT50
I get 8 blink code when I power on the TV. I have done some troubleshooting and observed the following:
SS-Board (TNPA5648-1)
- I have checked for transistor, diode, resistor shorts and everything looks fine.
- confirmed all cables are properly connected and continuity on the panel.
- when I remove the ribbon connection between SS board and A board (SS33/A33) the TV stays powered up and I measure the following on the SS board:
- TPVSUS = 210V, TPVe = 150V, TPSS1 = 60V
- A33 connector has 5V, 15V on the A-board side
- SC board LED... -
Re: Panasonic TC-P65GT50 8 LED blink failure
I just checked the datasheet for RFUH20 diodes and the legs are tied together. The leg-to-tab connections are not shorted on the diodes.
Q101 ~25M between leg and tab, ~46.7k between legs.
Q102 ~ 500k between leg and tab, ~46.7k between legs.
Do you happen to have a schematic for this board?Leave a comment:

Panasonic TC-P65GT50 8 LED blink failure
As the title indicates, I own a Panasonic TC-P65GT50 that just started experiencing an 8 LED blink failure mode.
I have performed initial troubleshooting.
1. When I remove the connection between the SS board and A board the TV powers fine with no flashing LEDs.
2. I checked the continuity on the plasma panel and the SS/SS2 boards and the resistance between pin 1 and pin 2 on all the connectors ~ 0.3 ohms.
3. I removed the SS board and have inspected and have not found any visual issues.
4. I found D051, D052, D053, D041, D042 are...Last edited by brent01; 02-17-2018, 05:34 PM. -
