Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
I have a toshiba 46h84 projection tv and it has been turning off by itself, unplug it and it will turn back on. now it just stays on for about 30 seconds and then turns back off, power button does not work or the remote, the tv is only 3 years old what could be the problem
this sounds like the convergence circuit going bad. it is very common on your model. it is some bad parts overheating. in time the tv will stop comming on. it is a good tv and worth a repair.
Here are few trouble shooting steps you can try:
ONE: Disconnect the power cord for 4 hours. Then when you power it back up the internal soft codes will automatically reset to factory defaults.
TWO: The whacking test is to just bang or smack the set with your hand on the back, side, top, etc., to see if there are loose connections or cold solder joints inside that are acting up. If so, the banging should knock them back to normal and the set should restore. You might have to use some creative banging and some have had to put a book or magazine under one corner to torque the chassis enough to get it to work reliably.

Did you try disconnecting from power and then plugging back after one hour or so? It is the firs thing to try.
