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.

Our daughter gave us a Toshiba TV and remote. We plug in the TV and hook up the cable,and try to turn on the TV but nothing happens. We can turn on the TV with the TV button,and it works fine,but we would...


If the remote is the original Toshiba remote, it obviously should work the TV. Have you checked to make sure it has good batteries? Also, if old batteries leaked in it at any time there may be corrosion on the battery contacts keeping it from working. Make sure the metal contacts look shiny, not crusty and corroded.

If the remote still doesn't work there are two possibilities. One is that the remote is just bad. You can get a universal remote, set it for Toshiba and try it. It will at least control power, channel and volume functions. If the universal remote doesn't work, the remote sensor in the TV would be the probable cause. Like any other part, they can sometimes fail.

TV locked with blue screen


Try resetting the TV to factory settings thusly:

Turn on the TV. While holding down the RESET button on the remote
control, press the POWER button on the TV. (The TV will turn itself off, then
back on again.) Release the RESET button.

Sony 46" lcd turns off by itself and will not power up again.


Sony TVs come with a one year warranty on parts and labor. Call Sony at 1-800-222-SONY They will find a local company to service this product.

These TVs have a self-diagnostic screen that a tech can access to help solve the problem. Your problem could be any number of things including the fan(s) stopping, the ballast board failing, Q-box issue or none of the above.

Sony 46" lcd turns off by itself and will not power up again.


if your tv unit is still under warranty, first you better bring it back again to the store you just bought it for warranty purposes, your tv has an internal problem, maybe manufacturer defect. Usually the cause of that is a shorted electronics component, say for ex, a mosfet transistor that is located at the power section, or maybe a capacitor that is leaky, and also an open resistor. if you don't know how to troubleshoot this problem, you better have your tv unit repaired by a professional tv technician.

Good luck
