Easy. However,Panasonic themselves will not sell those type of parts to a consumer. You must be an Authorized Service center. If you can find it on e-bay, that would be your best bet.

TH-42PX60U wont turn on. Blinks 10 times. replaced the power supply board, but the same issue.


What I'm learning is there are several models of Panasonic TV's that have a video card that doesn't play well with HDMI applications and the end result is, you need to call this number and not only make arrangements to replace the bad board,but also this!
Your model doesn't show below,but I'd certinly inquire about the necessity of a "Firmware" update!,,,Panasonic knows FULL WELL they have a HUGE problem here!
Hope this helps!

At panasonic.ca I found the listing for the fw update under customer support-important notices

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.

Sound, No picture


Try another video source. Try a digital source and an analog source. If you still get nothing, think about replacing the DG board and the H board.
