The high-pitched squeal usually indicates that the horizontal drive circuit has failed as a result of a dead line-output transistor. This symptom indicates that the control circuit of the main power supply is trying to over-compensate for a greater than usual secondary current. Certainly, an inspection of the line-output transistor will show that it's most likely dead. Sometimes instead of the squeal you will hear hiccups instead. Focus your attention on the horizontal circuit.

How do i connect cable to this tv


RCA Tru Flat has one of the best pictures for a digital flat screen. This exact TV is my bedroom TV in my home. As for the cable, you can run either a standard 75ohm coax cable or AV wires from the cable box to the back of the TV. Hope this helps.

There is a short circuit in the high voltage circuit. the transformer who helps to create the high voltage or his power transistor is damage. replacement needed. the repair is not expensive, because the parts are average repair. Ask for an estimate.
