You need to change the 1000uf caps in the power supply. only if you are handy with a soldering iron. Take back of remove psu. You will see them bulging at the top. Think there is 5 to change :)

SOURCE: 3 YEAR OLD SANYO DP 32746. SHUT ITSELF OFF, CAN NOT TURN BACK ON

If you leave the tv unplugged for 2 days (atleast) then plug it back in and try to turn it on and if it comes on its the power supply board. If it comes back on it will probably shut off between 30min to 4hrs and you would have to unplug it for 2 days again. All the power needs to drain out of the tv. If thats the case take the back pannel off and check the part number out on the internet. Not hard to do becarefull touching things the power supply does store a little bit or shock in it. Good Luck.

What does it mean when my plasma tv turns off by its self? its a panasonic viera plasma tv have had for bout two years


Basically when it turn itself OFF automatically all the time, the TV goes into "Protection Mode". This happens when there is a damaged circuit board inside the need to be replace and turn itself OFF to protect the other ones from being damaged.

A TV service tech will have to look at it to find out which boards need to be replace. There are about 7 different boards in your TV that would cause this problem.

Sanyo DP42746 42 in. plasma TV


Well I have the same problem with green light and no sound and no pix. After i opened it all up i checked the main power supply board and found all fuses good and the 12vdc side of the board dead. My best guess is this power board has many problems. All the driver boards for the screen are located on the perimiter of the screen. If you loose part of the power supply board you will loose part of functions of the tv. At this time i am looking to replace the entire power board. Will let you know the location and fix soon as i find it. jim jamesgibson@nycap.rr.com

Unplug the three red-blue-green plugs nest to the convergence amps. If the unit powers up and stays on the picture will look bad but will confirm that the convergence amps have failed...
Replacing the amps and one or more resistors in the yoke return will restore the set to normal operation..
Use only Sanyo original Ics..
