Question about Combination Televisions

1 Answer

Won't turn on.

The set won't turn on, when plugged in it emits a high pitched 'Eeeee' sound. Doesn't do anything else. No power up and a high pitch noise

    The Witch was right on the mark. The defective component was the horizontal output transistor (Q406) on the Toshiba TV model number MD13N1C.

SOURCE: Won't turn on.

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. Could be anything from a bad startup resistor to a shorted horizontal output transistor to a bad controller. It is probably something simple but you will need to do some troubleshooting. Start with the low voltage power supply. Take care, and good luck

High pitched sound


Sounds like you have a coil or transformer that needs resoldered. Possibly in the hi voltage circuit but sounds more like a transformer in the switch mode power supply...

TV making high pitch noise, stop working.


It must be the horizontal output transistor, it maybe short circuited. A short in flyback.

High pitch buzzing and no picture


Your power supply, I mean the internal power suppy could be faulty, if you know how to deal with it, check it for abnormal oscillation, or get some help from someone who knows how to repair it.

High pitched sound


you can fix this if you are very careful. it is call a high voltage leak. inside of the tv, close to where the power comes in will be what is called a high voltage transformer. if you are electrically inclined, unplug the tv, take the back off and then hook the power line up and turn the tv on. with the lights off in the room and a flashlight handy, look at where the sound is coming from. locate where the sound is coming from and look very carefully(very carefull not to touch with your hands or head to any part) for a white-ish blue arc of electricity. if you can see this then that is where the problem is. to fix it you will need to put something in between the two places that it is arcing from. a piece of plastic or silicon putty or anything non-conductive will work. again, be very careful or you might get the dogsnot shocked out you.

Power light comes on, followed by a high pitched whine


Hi, If after trying the TV again later and problem persist, repairs are in order. A high pitched whine is an indication of a fault at the horizontal section of your TV. The horizontal provides the high voltage for the picture tube. Your best bet maybe to seek the services of a qualified professional TV repairman since this involves component level repair, soldering/desoldering, use of soldering iron and VOM (testers) and knowledge of circuitry. Good luck and kind regards.

18 Mo old Samsung CXM2785TP made high pitched noise and lost power


The high pitch sound could have been the flyback transformer. check the horzontal output transsitor if is gone the tranfomer is sure to be gone . Tranformers are varying in price are the transistors can also vary you could be looking at around 150.00 plus labour.
