Question about Sanyo Televison & Video

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

I have a Sanyo 32 inch tv, model # DS31650, that my neighbor was throwing away because there is no sound. The picture is fine, but even with the volume all the way up there is just a bit of a hum. Any help getting this fixed would be greatly appreciated, as I was hoping to use it for my PS2 instead of the 20 inch I am currently using.

    Thanks guys, I moved every dial I could find on the board, then tried to get them all back in the exact position they were in before. Now the sound works, but only through the video link, not for cable TV. AND, the color is a little off. But at least I can hear the video game and that is what I really want it for. I am going to try to correct the color problem. Thanks again for the help

    thanks for the help. turned out the color problem was from unsheilded speakers that I was using to replace the original ones in the TV. After getting the sound working, I replaced the original speakers and the color problem was gone.

Actually the coil doesnt need replaced. on two sides of T131 one side is a cap labeled 103 and the other is a small resister labeled grey red red. 8.2k ohm. I have one in the shop that i couldnt adjust the t131 to get the sound back so i just replaced the resister and cap and there was no adjustment needed on t131. the resister does not need to be a small one as i used a half watt in place of the quarter watt one. and the 103 cap can be found in old scrap electronics. make sure that the cap is labeled the same with no extra markings. should look exactly the same.

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

Sound no picture on Sanyo 32 inch flat tv model number DP32648-02 how long has this been a problem for Sanyo?


Circuits fail with time no matter who the manufacturer is. That's what warranties are for. If yours is no long in warranty you can get a replacement T-con board and replace it yourself. Get the part from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

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.
