Is there any noise coming from the cable box? My TV had similar problems, and when I had Comcast change the faulty box, the problem stoped

I was watching tv and out of nowhere the tv turned off and now will not turn back on for more than a couple seconds. When it does turn on it makes a click noise then turns off,

If the tv has nothing happening at all when you try and turn it back on including any noise, your power supply is broken. If it is still trying to turn on or does make noise, an internal component has come loose or been knocked off, most likely to your picture tube.

The Flyback Transformer is probably shorted to the core and shorted out the Horizontal Output Transistor. Changing both will probably fix your problem. Let me know if this helps.

You can get the replacement Flyback at the following link, and they provide free instant messageing tech support to take you step by step with the replacemnet proceedure. You need phillips 32942 flyback, its listed in their flyback catagory.

Shorted Horizontal output transistor caused by bad horiz
transformer....parts to replace = Asti 2078 ( 257805 ) xformer
and 237470 RCA xistor..............................T.

It sounds as if the lamp needs to be replaced. The buzzing sound you hear is the ballast attemting to fire the lamp.

try to check the menu your the timer is on.if not resolder the main board of your tv.

The horizontal output transistor drives a transformer that gives you the high voltage to light up the picture tube,either the transistor or the transformer have gone bad,sometimes both have to be replaced and sometimes the transistor fails for no reason by itself.Be safe and call for help if you are not familiar with tv service.
