    When I turn on the power with the remote the TV comes on for a  brief moment and then shuts itself off.  The red power light flashes, but I can't get the TV to go to any of the menus.  Once before this happened and I discovered that a sleep setting had been programmed at the store where I bought it.  But this time I can't even get to a point where I can eliminate whatever setting is causing this problem.

In protective mode the tv does not turn on and light is blinking, typically we must proceed by elimination as some faulty sections are preventing the tv to switch on. unplug the output power connectors from the power supply until the latter stop clicking. if it is still clicking after every of the output rail have been disconnected, then the power supply itself is faulty.

hope this helps!

Something inside has failed.
The flashing is a code for the repair engineer to tell him/her what is wrong.

Panasonic th-42pz77u has no picture.power light (red) flashes 7 times


seven blinks on this model is the SC board. it will need a new SC board and the software update for the new board. usually only authorized servicers have the software need to do the upgrade. but if you were to contact panasonic then they might be able to have it fixed for you for free since this was a defect in manufacturing. of course this depends on how long you have had the tv.
