Question about Sanyo AVM-3257 32" TV

2 Answers

Power TV shut off for no reason. When I turned it back on it run for 2 or 3 seconds and shut off. After tring a couple of times it wouldn't even try to turn on. I unplugged it from the outlet for 30 min. then tried again, would turn on for a couple of seconds then off. It will not even try to turn on if it's been plugged in for any length of time.

Chances are this is a power supply issue, I had a slightly larger Samsung set in here a couple weeks ago that acted the same way, would power up for 3 or 4 seconds then get less each time I tried to power it up to where it wouldn't come on at all and it was the 12 volt power supply giving issues, I changed the FET and driver transistor and it fixed the set, but unless you have a fair amount of electronic experience and some good test gear its going to be easier to just change the board, they aren't that expensive

Possible fault on the power board or panel as the TV seems to shut off on a protection.
Need to investigate on these boards for any physical failure preliminary
before starting on a circuit check.

You probably have a bad flyback transformer (high voltage). You might want to get an estimate to find out if it is worth repairing. Stargazer

SOURCE: Sanyo 24" flat DS24425 suddenly turned off, won't turn on

Solution to the won't turn on or turns on and turns off in 3 seconds thing...as my Ds24425 did.

First thing is very important...unplug the TV and let it set for 24 hours before you proceed.

The voltages inside a TV are EXTREMELY HIGH and LETHAL....so proceed with caution!

Place the set face down on a towel on a table and remove the back cover....hex screws around the perimeter and 1 phillips screw near the inputs.
The main board will slide up and out. unplug the degausing coil "white plug with two wires" and the speakers connector. This will make it easier to turn the board and take a look.

What I found with mine was a bad electrolytic capacitor. You can identify I bad cap "capacitor" by examining the tops of each one for bulging or signs of overheating "melted or bubbled plastic covering." The cap in question was C626 with a value of 1000uf, 16volt. I replaced with a 1000uf, 35volt and it works perfectly. The cap is located about center of the board. Carefully unsolder the cap and remove, make sure to install the new cap with the proper polarity...the board is marked with a dot indicating the negative lead of the cap.
Be sure to reattach the white plug and speakers connector and slide the board back into the plastic grooves. Then replace the back cover and test. Good luck! ...Daddio

Mitsubishi TV, WD 60735; TV shuts off shortly after powering up.


It could be but a couple of other possible reasons---they had problems with this set and its brothers with caps in the main power supply puffing up and causing this "hard to turn on" issue.

A second reason is dust/dirt inside the unit.

All air is coming in via the front of the set and exits the rear--enough dust gets inside and the fans slow down or the lamp gets too hot and set shuts down---don't try this in the house: we take them with back cover off outside the building (on a ramp) and with air clean them out completely--try not to blow it inside the screen. It looks like a dust storm in most cases but can cause exactly the problem you have.

Turned on the tv, heard sizzling sound and it immediately shut itself off. Won't turn on now. It had been turning itself off periodically now and then for the last couple of weeks with no noise and then...


sounds like dust collected on the internal parts which after enough time can cause it to stop working. either have tv repair specialists replace the mother board, or replace tv

Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.

TV turning off


INtermitant problems as the are called usally mean bad solder connections...the joints between electronic components. this set when it has a problem shuts down. This is safty cuircits. It could be a connector. when the set shuts down. it locks out for a period of time.. DO you have to uplug it to reset it? IS there any sounds. Without know more i would guess its high voltage.
