Panasonic tx-43fx550b no picture but has sound
I have a Panasonic tx-43fx550b it’s only 18 months old it has sound but has no picture
the red standby light keeps flashing and Varys between 21 - 22 flashes
As far as I could find, 11 blinks means there is a cooling or fan issue, though it could also be a power supply issue. Try resetting the TV first. Unplug it for a full 20 minutes, then hold the power button on the side of the TV for 15 seconds. After that, plug the TV back in and try to power it on. That will rule out any easily fixable power issues. Let me know if that does the trick.
