The display went dark during a short period of use. No sound or picture. Front power LED stays illuminated red.
I unplugged the power cord for about 30 minutes and plugged it back in. When I press the On button on the front panel I can hear a few micro-relays click and the power light turns on red. But still no sound or picture. Also, I can not turn the set off (red power light off) with the remote or the front panel power button (Lock Mode per service manual). I have to unplug the power cord.
When the front red led is on, and I hold down the power button, it will blink 14 times repeatedly.
This happened to me as well.
We heard intermittent tones from the Verizon FIOS hardware mounted in the foyer
closet. SHortly thereafter, the pic and sound were lost. The remote (either the Verizon
or Panasonic) will power up the TV but there is no pic or sound. The power
lamp is continuously illuminated. We still have internet access via Verizon's
wireless router as well as Verizon telephone service. All three services enter
the house via the hardware mounted in the foyer closet. The Verizon remote
will cause the channels to change on the converter box as well. The TV is
Panasonic Viera TC-P42S30 and its less than 3.5yrs old.
