No power with Sanyo TV

Sanyo TV, model DS31650, suddenly has no power. Sanyo customer support suggests that it needs a new fuse. Sounds simple enough, except which one of all the thingys in the back of the TV is the fuse? What does it look like, should I be able to replace it myself, and where would I get a repacement? Home Depot? Best Buy?

The problem was fixed at a repair shop. They "replaced thermistor in degause circuit adjusted as necessary". The part cost 19.95.

I have a new Sanyo tv and cannot get sound on 6 channels! I originally received sound but suddenly left.


It sounds like your secondary audio (SAP) has gotten turned on. Look on your TV remote for a button that says MTS or Audio and press it until the screen says Stereo. If you are having difficulty locating how to turn off the secondary audio feel free to repost with the model # and Manufacturer (Sanyo) and we can try to help you further...

Good Luck....

Have a Sanyo tv model DS31520. Won't turn on. push power button, nothing. checked fuse on board-o.k. Power to circuit board. Any ideas what to check next?


Sounds like the switch is missing the mark behind it. Take the back cover off and see if the back of the push ON switch has been worked loose from pressing.

Hope this helps bud.

Vertical line in center


If the line is "vertical" then the vertical circuit sounds OK. The problem would be in the horizontal deflection.

Check yoke connection and solder around horz defl circuit.

If the line is horizontal then I would suspect the vertical IC.

I have a Sanyo 32 inch tv, model # DS31650, that has no sound


there is an SIF coil (sound-intermediate-frequency) that goes bad on these units. it will be near the video jungle ic and marked sif on the board. since your sound is poor anyway you could try to adjust, in very small incremens at a time to see if audio picks up. sometimes dirty connections in the coil will cause poor conductivity, by turning this will move contact to new position mch

HT27546 turned off and won't turn back on


Sounds like it is probably just a fuse inside the t.v. May also have a bad diode. I would take it in for an est. if you don't feel good about replacing the fuse. Always have your t.v. unplugged when working on it.

If the set runs at all, your flyback and output transistor are good. If the set shuts down after a few seconds and the sides are wavy, it usually means that the main B+ in your power supply is too high and not regulating properly. I do not know what kind of power supply that model uses, but if has an old-style STR regulator (like the STR30130) then it is probably shorted, and if the set uses a switching power supply then look for an open or leaky electrolytic cap on the primary side. If the power supply is working correctly and the set shuts down, check for an open safety cap (the large 1.6 - 2Kv cap connected to the collector of the horizontal output transistor).

It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
