How To Fix a Panasonic TV that Won’t Turn On
Panasonic TV Troubleshooting No Power The first thing to do when your Panasonic TV will not turn on from standby is to check your remote and the power plug. It could be something as simple as dead remote batteries. If you have your TV plugged into a power strip, rule that out as the culprit. There is one step you can take here, both as a possible fix, as well as a diagnostic evaluation
1) Unplug the power cord from the tv
2) Wait at least 1 hour (60+ Minutes)
3) Press and hold the power button (on the set, not the remote) for 60 seconds
4) Keep holding power button while plugging back in, and for another 60 seconds after. When plugging back in, go directly to the wall outlet, bypassing any power strips or surge protectors.
If this reset process does not work, it would unfortunately confirm an internal hardware failure.
