wade Jones so if I understand you correctly, when you "push" the power button the power LED light turns on. When you then push the power button and hold it, you get the power LED to blink 14 times. Is that correct? I am old so the "hit" and "mash" of the power button confuses the heck out of me.


My TC-P42ST30 blinks 14 times, repeatedly. Holding power button down can stop this but it will resume upon releasing button. Only when removing power from the set for say a minute will the flashing stop. Trying to turn on the set will resume the 14 flash cycle

wade Jones start with this information:

14 BLINKS This code is triggered if there are abnormalities during data exchange with the standby CPU ROM. No F15V connected to the A board at plug-in (Open connection of both pins 10 & 11 between P6 and A6) Shorted F15V developed after the TV is up and running. Holding the power switch for over 5 seconds after the unit has gone into shut down and it’s in lock mode with the power LED solid red (Note: the LED stays on if the power button is momentarily pressed). Commonly failed boards are the A- P

This model also has issues with the SC board " if you have a multimeter , measure the resistance at Vsus lines to the SC and SS and see if dead short. TV off .

If shorted then you'll have to isolate Vsus power to each board (SC , SS) and check at the SC and SS connectors.

Or , remove the Vsus power lead from the SC, turn the TV on, if the front LED starts flashing like it's starting up and then stops with a different SOS code (other than solid or 14 blinks) that would indicate what was just removed was shorted.

If no change, reconnect (check there's no residual voltage present), do same for SS. From here

Could be SC or SS.

so as you can tell you will need a multimeter and it will really help us to see your boards. Post some good pictures of your boards etc., with your QUESTION. Use this guide Adding images to an existing question for that
