    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?
