How do I fix a tv that turns on but has no picture or sound?


if it has no sound or picture then it must be the power supply .

I have a memorex. I am getting sound but no picture. When powered on, the memorex sign shows up but then no picture just sound. Also makes a slight screeching sound for approx 10 sec. when powered on.


I guess the blanket draped over the TV is intended to give it a "timeout". Anyway, you will likely conclude eventually that the internal power supply has failed.

Tv pops on and off suddenly after viewing for about 10 to 15 mins. this problem becomes progressively worst after prolonged viewing. as of today there is absolutely no picture and or sound.


Your symptoms exactly match this scenario: a component involved in picture & sound was failing intermittently, then progressed to a hard failure.

My suspect: a power capacitor in the power supply. They sometimes fail this way - when the dielectric breaks down completely, then the power supply fails, causing no pic/sound.

Fix: replace power supply (or the specific capacitor, if you can determine which one died).

Same thing happened to me


Well, no sound no picture = power supply unit
Sound no picture= flyback
picture no sound =tuner/audio logic

You get my drift?

You power supply is bad you replace it you got another new TV, with this digital conversion hitting I would rather advise you to get a nice flat panel and donate that one to Goodwill

While watching the TV the picture suddenly went out - still have sound. Turning the TV off and on again does not help - the POLAROID Logo displays, but when the station connects - still no picture


possibly external power supply faulty under load it may fail these power supplies ofen have capacitor failure open the power supply to check for leaking/bulging/swollen capacitor is around 2000uf rated at 12v

RCA 32 in TV no picture no sound just a beeping noise TV power is on


the tv has one part of the power supply working this is needed to have the microcontroller ready to work. But the tv needs more than that for work im talking 'bout the high voltage power supply who is now damaged. the parts required depends on the diagnosis in the bench but at least two are needed. the cost of this repair of course depends in how many parts are going to be replaced, but i concider this repair kind of average in this technology.

Hello cote,

This indicates a problem in the power supply either the low voltage switching supply or the High voltage power supply. The sounds you hear is the shutdown circuit activating, I would not suggest that you try to repair this problem because of the dangers involved. I would suggest that you take it to a qualified TV repair shop. This problem should not cost you much, however it is the best choice for the problem you described.

I hope this helps,
Thank you,
