After changing the D board, have returned it and put the old board back in now it still trips out but there is no screen light at all.

Thanks for the reply, this fault started has a 2 blink, then changed to 12 blinks which is what it is now and have checked lots of voltages but have not found any problem and at one time was coming on for some time but no sound and could only get PC video. So if you have any info on 12 blinks, help would be appreciated. Have checked the speakers and voltages.

On these older Panasonic sets the audio amplifier is on a separate PCB, have you made sure that is fully seated and all connections in, if you have been fiddling with the set it could come loose.

Tom66 if you see info on 20, says that if I remove plug D3 the power stays on but have changed both board at each end of the connectors, still get the same problem. You still think it is the audio ??

Does anyone know a procedure for finding the problem, when the power light is blinking 122 times

Re: Panasonic TH-42PE30 fault no picture fault code 2 blinks

Sorry, the above should have been 12 times
