SMPS circuit problem Check the SMPS . Replace opto couplers.

Do not switch ON TV without opto coupler in circuit. SMPS will go out of control and the + DC voltage will raise and spoil the circuits.

My tv will work for like 5 min then it shuts off


Hello,

Sound like you have a overheating problem. Your capacitors might have reached their end of life thus making them overheat quickly. Try to check if there is a fan inside your TV. If there is a fan, try to clean it see if that helps.

I hope this helps. Have a nice day.

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.

Will not turn back on


Take off back cover. The problem power board is to the right of the board where the power plug feeds into the TV. There is a large white fuse right bend the power plug. With a meter it read ok; about 8 inches deeper into the TV on that board was the resister next to two fuses. My 4 amp 125 volt fuse did not read on my meter. After replacing, it worked fine.
