| I don't know what service manual you were looking at but a 3 blink for a TH-50PX75U is a 3.3 volt SOS which means D board or power supply. Turn the unit on, is pin 12 of CN P25 of the P board high before it shuts off? No D board, yes, power supply. | |

Will a SECOND service manual help?  |

|
| Hello, I have a 50 inch PANASONIC TH-50PX75U plasma tv. Currently it does not start up when turned on. I get a flashing standby light once every three seconds. I found the service manual and troubleshooting indicated it was the A-board. I replaced the A-board but still seem to get the same problem?
Any ideas? |
