Question about Panasonic PT-51HX40 51" Rear Projection Television
TV changes the channel (always "up" one channel) at random intervals. No other pattern detected. Does not matter what is being watched (Cable, DVD, etc). When it changes the channel it goes to a different input and screen changes to snow. Have to press tv/video button to get TV back to the correct input (Componant 1). Removed the batteries from all remotes and still get the problem. This started 2 wks ago after repairman came out to change a capacitor ($400) that blew out on one of the boards. Called him and he said the part he fixed would not cause this problem. Starting tonight I get the following code displkayed on the top left of the screen: CHK 0D36D 000000000. Ideas?
Check over the powerboard... I am having the same issue and I believe after looking at it briefly tonight that It might be cause by a cold/cracked solder joint..
Slide the board tray out some and back in with a little bump to kinda jar anything loose... Not hard...
You can also remove the Power Board and check each and every connection for solder quality under a Microscope... I am certain it is within this board I just have yet to have time to isolate it completely... Today was the first day I was able to open the Set up myself...
