What is cnveyance setting for

Only one bad door switch should do that

The 20 min time out is the GEM or Body Module,
which is normal only because you have a bad switch,
otherwise it goes to sleep when either front door opens

Put radio on & open a door,the radio should go off
& kill the time delay if no issues exist

it looks like it could be a virus or malware because if you use the internet and are using windows through your ps3

it sounds like a buffer or video pcb problem not much to fix if you can source parts

sounds like it needs retuning try doing that see if it sorts it if not at back of tv inside there is a fuse try changeing it

could be the thermostat stuck closed not leting water circulate to cool,,or could be the radiator fans not working too....

YOUR LAMP IS BAD.

This can be so many things, could be the color wheel, lamp, etc...depends on the type of tv.... If you got it from Best Buy and are in your 1 yr warranty or if you bought the service plan ( a must with any electronics) then give them a call and you will be all set.

your set must have cold solder joints,this means once set gets hot enough that connections are then made correctly,this will not stop untill you have someone solder all cold solder points.

this is due to loose contact in power supply.

it might be due to some capacitor or print loose in supply.

please also check your plug & socket for loose.

it is not a major problem

good luck.

 

With it only being about 3 years old, I would suspect bad solder connections rather than defective components like Capacitors. You may get the symptoms to come and go by slapping the side of the set or jaring it slightly which would prove the bad connection thesis. It is not a permanent cure however and you can make it worse if you keep doing that. A solder repair shouldn't run over $225 in my opinion.
