I have a Vizio m501d-A2R that keeps powering off by itself. I need to unplug the tv and replug it in for the tv to turn on again. The sound and video are perfect. what needs to be replaced?

This is usually down to a safety feature cutting out the Television from harming itself. Or quite possibly a fault that make it turn itself off - it may well be thinking it's receiving the command to turn itself off. Either way, it's impossible to find out without opening it up. A professional repair is the only way, check up on your warranty. You may want to plug it into a different power source, just on the off-chance that it may solve your problem - but don't get your hopes up.

SOURCE: no video, shuts off then back on

I checked Toshiba's website and found the manual for the set. The self restarting was indicitive of a lamp failure. The red light was solid while the green light blinked. It would then restart 8 times before both lights would then begin blinking.

there a problem on power side.. chage the ic and the resistor going to ic and check also the signal diode.

Without seeing the set and takig some measurements, I can't say for sure where the problem is, but the part info is listed below. These can be purchased through tritronicsinc.com. Please note that these boards have a "core" cost. This means that the "core" amount will be refunded to you once the defecive board is returned.

this could be one of two problem. first, check if you have back light. If you do then the problem is with the M/B. Second, if you don't have back light then the inverter is bad and needs to be replace.
