Dead with a high pitch sound while plugged in.

My Sanyo t.v. model number DS25320 just stopped working. The screen does not come on, but there is a high pitch sound that comes from the T.V. while it is plugged in. What suggestion do you have?

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

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.

By high-pitched, you mean it is not that same frequency as when it's cooking? Is the tone near or the same as the beep you hear when you press a key? Please post a little more information so we can help better.

High Pitch Sounds


In this model the horizontal drive coil vibrates and makes a high pitch squeal. Most times it is intermitent. Touching on the coil with something (non electrical, like wood) will make it stop or change it's pitch. The fix my shop uses: It's not to technical, but, we put fingernail polish around the coil. It's a remedy I've used for decades and has always worked. Some shops use a hot glue gun. With the back open you can hear the coil to locate it. When fixing the problem have the set unplugged. When a technician is working on a television while it's plugged in. He uses only one hand and stays away from the high voltage.
