TV will not turn on, is my picture tube out?
TV does not tirn on at all. When i press the on-off button, the led flashes and for every time it does flash the tv seems to make a quiet noise as if its trying to turn on but doesn't. I un plugged it for a while but same thing happens. I'm going in to try to locate sourse of "quiet noise"

Re: TV wont come on
Some electronic components inside your TV had shorted out! you might be hearing a slight CHIRPING! like the sound of crickets! or maybe whining! the sound migth be coming from the transformer/inductor with a shorted component on its output!

Check if all buttons are working fine. Testing remote is easy. Use your mobile camera. While watching the LED in the remote through your mobile camera, press buttons. When you press button the LED should light up. You can't see with naked eye but can see this LED flashing through camera.
If LED is flashing for all buttons, then something wrong with the TV. In your case, buttons in the TV are working fine so TV has no problem at all. Your remote should be the problem.
is the led flashing? if the led isnt flashing but is lit then press the power and menu buttons in together on the front of the set and hold them both in together and see if it flashes a two digit blink code. then let me know what happens. If it blinks constantly let me know that as well
When the set ends up flashing the LED, it should be a repeatable count. Can you please report that count here? Also, since the set eventually works, I'd suspect a bad connection or a part that has changed value over time. The blink code will help to narrow down the offending circuit.
Red LED flashes probably five times.
You have not mentioned the model no, so I have to guess it is few years old model.eg FE2 chssis or similar.
Most common reason, R618 270k ohms in power section has gone high.
Second, screen voltage control is slightly misaligned.
Third, high value resistors on tube base, normally two connected to screen voltage control pot have gone high.
You need to have some knowledge , a multi meter and soldering iron and know safety procedures before trying yourself.
Is this set hooked to cable? Is there a cable or satellite box? When you press the menu button, do you see the menu on screen? Do you see anything on the screen, such as snow, or is it completely black? If the signal is OK and the TV has no picture at all, the red LED on the front of the set should be flashing a certain number of times. If the LED is flashing, the computer has detected a problem in the set and shut the picture off. If this is the case, there is no way for you to bring the picture back by pressing buttons. The number of times the LED flashes is the computer's way of displaying exactly why there is no picture. The set should then be serviced by a qualified tech familiar with Sony TV's. If the LED is not flashing and the menu comes up on screen, check your signal source. If you are using a cable or satellite box, that box could be bad, and if you are using RCA jacks, the yellow (video) wire could be bad or pulled out.
