Set comes on when plugged in wall
The blue circle power button does not turn off set
volume quickly lowere to zoro
on side control panel, only menu and volume are active but does nothing for volume and menu is useless without the active channel buttons working
The set has clear picture
and sometime a blue banner stays on the screen with the words "No Information"
Trials:
purchased main power board and set worked for about an hour then back to symptoms above. I re-solder almost every contact on my original board and again everything worked but this time for 10 minutes.
that told me the problem is somewhere else.
solution:
removed the other power supply board ( standing up right located to far right if you are sitting behind your set) and found large cap 450v 100uf so very slightly swollen on top (Attaching pics of old and new cap).
Replaced cap and as of now the set has been running flawless for 5 hours. Going to let it run till bed time and promise to update if I go back to square one.
Hope this helps someone.
