Was working fine last night ,went to turn it on and you can hear a buzzing by where you plug in your jacks a bee,or high pitch has no picture or sound.only sound you hear is this buzzing

Sounds like your power supply is causing the problem. Unplug the TV wait 10 minutes, look in the back for a red button (circuit breaker) push it in. If this does not work you have a low voltage power supply fault.

A shorted horizontal output transistor or shorted flyback. If the flyback is shorted replace also its HOT.

Sylvania SRT2232S Powers On, No Picture, High Frequency squeal

Hello there. I'm sorry to say that it sounds as if the element that actually energizes your screen is bad. It is most likely overheating. or quite poosible the power converter lost a resistor or 2.

Stopped working and squealing sound

Your set is shorted circuit condition. The power supply is making the noise. Unfortunately almost any of the hi current circuits will do this. If picture went out 1st look for video or hi voltage problems.

Power light blinks and no picture

No picture - screen is empty. Sound is ok
Check IC101 (BA7630F), if video signal comes to input (pin 1) but not present at output (pin 14) then replace this IC
No picture and sound, only a high pitch sound at switch on
Remove horizontal transistor and measure the resistance across any two pins. This value should be no less than 200ohms
Picture fades away few seconds after start-up till no picture. Sometimes no picture at all. Sometimes picture OK for longer. Sound unaffected.
Faulty joints on CRT pcb. Cracked solder joints at tube socket connections on CRT circuit board. Caused variable supply to CRT heaters. Resolder all socket pins to pcb.

No Picture

Rarely picture tube also shows the same symptom. High pitch sound is due to through deflection area LOT power supply is loaded. Compulsary horizontal output transister short. From your statement i think Lot puncture takes place. Change LOT and horizontal output transister and check tv is now working.

TV makes high pitched noise

In 1080i the horizontal frequency more than doubles from 480i. This means that possibly the high voltage transformer or a linearity coil is occilating at that lower frequency.
