If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. Squealing noise is from the power supply teling you that there is an overload condiction. The overload is shifting the operational frequency of the power supply into upper audio hearing range. Check the diodes and caps in the supply circuit and the active components in the deflection circuit. also resolder the LOPT, h-output, h-driver, and h-driver transformer. Good luck

Can you switch from tv to video input on sanyo ds31520 tv without a remote

no you require the remote or a universal remote or sometimes a cable remote that has been programmed to work the volume on the tv set will have an input button .

If the TV is less than one year old, I would suggest to call the place where you bought it from and ask them for an authorized repair centre.
The TV should be still covered under manufacturers warranty.

Sanyo DS31520 TV

I am relentless when it comes to problems like this. I had the same problem with my TV being stuck in video mode. I found out that there is a reset button......It's on the @*&#^&^ original remote!!!!! So I tried programming my Time Warner Scientific Atlanta AT8550 remote for the TV to see if the "video source" button would work. IT WORKED!!!! You have to use code 1062. Instructions are:

1. Turn the TV on.
2. Press and hold select and the TV keys until the lights blink twice.
3. Enter 1062. All mode keys blink twice to indicate that the code was accepted.
4. Point the remote at the TV and press power to test the TV.
5. You can then successfully use the "Video Source" button on the bottom left of the remote to change the video mode. VOILA!!!

If you don't have a Scientific Atlanta AT8550 remote, I'm sure you know someone that does. They're everywhere!

No picture, have sound

If it is latest tv check you have changed blueback option in menu(available in some model), then check the given source cable is proper. Suppose if it is old model there is dry contact in solder points. Otherwise make one general service by authorised service provider.

Sanyo DS31520 31" whining, high pitch screech, very annoying!

two audio out RCA type lacks a red and white. only thing I can think of is make sure nothing is connected to the outputs unless your running it to a stereo. now for the inputs are 3, video yellow ,left and right audio is white and red, make sure the yellow has yellow input rca plug. still problems take them all loose and see it feed back goes away.

No picture only a high pitch sound

Yes,it can be repaired,sometimes for no reason components fail and they need to be replaced,if you are familiar with tv service you can check the horizontal output transistor,it might have gone bad(shorted out)and is all is going to take to get the set back running,sometimes the output trasformer damages the transistor and both have to be replaced,first just change the transistor and if it blows up again then replace the transformer,if you are not too familiar with servicing a tv be safe and call for assistance from a servicer,if you take the set to them it should be expensive.Let Us know how it goes or if you need more information.
