Check for power where it plugs in
SOURCE: won't power up
This model has had problems with the keyboard buttons on the front panel,causing them not to work and canceling out the remote operation. To verify this,you need to remove the front panel so you can access the connector on the keyboard pc board and unplug the connector.After doing this,see if the remote control is able to turn on the tv (wait for it to power up because with the connector off, the green power light will be disconnected and will not light up when the tv is on) If the tv works, than you will need to change the ten individual switches on the board - part# 432P089010 (or just use the remote only)
SOURCE: on/off button flashes green, unit will not turn on manually or with remote
PRESS THE TV BUTTON OF YOUR REMOTE CONTROL FOR FIVE SECONDS AND YOUR TV WILL TURN ON.
SOURCE: only vizio light come on then nothing. have to unplug to turn off
there a problem on power side.. chage the ic and the resistor going to ic and check also the signal diode.
SOURCE: is there a reset for the a/c unit itself
check for fuses in disconnect at the out door unit or a reset button where the copper line set goes into the unit at make sure stat wires have not been damaged hope this helps
SOURCE: Receiver shuts down after loud bang
No fix to this problem. When my T763 had the same symptoms I left it with the dealer who sent it on to service. It ended up being scrapped. So I'm afraid this is the end of your receiver unless your techies are better than the ones who worked on mine.
