27 inch tube tv won't stay on

Hi i have a 27 inch maganavox tube tv and it keeps shutting off and sometimes very hard to come on. Sometimes when it comes on it makes a whinning high pitched noise and stays on for about and hour or so. It has nothing to do with the timer, it just cuts off. It starts off by the picture on the tv starts to pull and stretch away from the corners of the tv and then i hear this click noise and it shuts off. what is the problem?

You have a problem is in your horizontal section which also is part of your power supply. The high pitched whine is from the Intergrated High voltage transformer (also called the flyback transformer). This sound occurs when the freuency of the transformer changes and or the voltage gets too high. The click occurs as a result of the drawing of excessive current by the HOT Horizontal output transistor. This is repairable, but requires the correct equipment and a schematic.

RCA TV, model number 32V550T. No picture but sound is fine.

hiya

this sometimes is quite simple to fix as it cud be a dry joint on the circuit board where the tube motor sits.


or it cud be the tube is on its way out, which wud be cheaper to buy a new tv rather than have it fixed

27" GE TV with loud Popping sound

Could be a possible flyback. yes.. for a 27inch i would not think it would be worth it... 27 inch tvs are realativly cheap.. the lowest price to repair would be about 200 if you got lucky.

My TV keeps shutting off

Tvtek is on the right track. The remote will not solve the problem. Sounds like a voltage regulator in HV circuit if it only lasts a few seconds. If it stays on for a couple of minutes, beam limiter cicuit is pushing to overload and shutting unit down. Magnavox set not hard to repair, but a 27" set is not cost effective to repair either.

Sony 27"TV will not turn on

The picture tube on your tv is dead, you need to replace it. It probably will be worthing just purchasing a new set, because the cost of repairing it will be close to the purchase of a new one.
