SOURCE: TV will not come on

How old is this TV?
Sounds like it has high voltage failure.
(If you hold your hand on the screen when you try and turn it on, do you feel the static? )
Unless the set is over 10 years old, I would overhaul the high voltage circuit. Should cost under $200 at a shop.

SOURCE: when my rca 36F530 tv is plugged in it makes a high pitched buzzing noise picture does not come on

There is a short circuit in the high voltage circuit. the transformer who helps to create the high voltage or his power transistor is damage. replacement needed. the repair is not expensive, because the parts are average repair. Ask for an estimate.

SOURCE: rca tru flat tv has a red picture

Is your video input (from cable or satellite or fiber optic, etc.) coming from a coaxial cable, a component cable (red, green, and blue connectors), or an RCA cable (yellow connector for video)?

If you can, try an alternate input method and see if that makes a difference. Does it happen when watching DVDs or tapes, or when playing video games, or just when watching television?

I have no control over my TV.


Hi,
This kind of symptoms appears when System Control IC have cold solder joints. Please check below picture mentioned IC101 to be resold in your TV main board.

If you have good soldering skills and familiar with TV, you can do it at your own.
Good luck.

Hi: My Magnavox flat screen turns on and off. It also makes a high pitch noise and then there is no sound and it also shuts off. Is it worth fixing?


Hello, what's the model or size of screen for the magnavox, the high pitch noise could be an audio power amp starting to get intermittent, and the power on/off could be due to the over current sensor circuit detecting the audio problem. Depending on the model number you would have a seperate power, audio and signal board in the TV. If he TV is 27" or smaller all these circuits are part of a mother board.

I have an LG Flat screen TV approximately 4 years old. It has developed a high pitched vibrating noise which is coming from the sound and not from the TV itself if that makes sense. If you turn the sound...


It sounds like the problem is caused by bad filter capacitors in the power supply section. Do you get the same problem when you use the audio line level out RCA jacks, if you don't, then the problem is in the power amp sections, the TV uses Class D power amp to drive speakers.

My rca tru flat is NFG


The high-pitched squeal usually indicates that the horizontal drive circuit has failed as a result of a dead line-output transistor. This symptom indicates that the control circuit of the main power supply is trying to over-compensate for a greater than usual secondary current. Certainly, an inspection of the line-output transistor will show that it's most likely dead. Sometimes instead of the squeal you will hear hiccups instead. Focus your attention on the horizontal circuit.
