Hello
The LOT [Line Output Transformer] of your TV has damaged. It is the one, that supply all the voltaged needed to CRT. Its internal windings will get shorted in between, and is irreparable. Replacement is the only remedy to this proble. Replace the horizontal output transistor also with this. you haven't specified whether there is picture with your tV or not. If this high frequency sound is along with picture, there is some loose in the cores of the SMPS transformer, or LOT itsef. If there is no picture at all, and this high frequency sound is there, no doubt; LOT is damaged. OK.

Check your TV settings under Caption, odds are someone adjusted the captions to text1 or 2.. the box should go away after you change that to off or std cap.

I have worked on many JVCs with similiar problems. I found in most cases the Horizontal Output Transistor was burned out or the Flyback trasformer was bad ( or both ). Also a likley problem is cold solder joints in the power supply section ( start up trasformer is a good place to start ) and also check the resistors connected to the start up circuit. Anyway, the problem seems to normally be in the horizontal section or cold solder joints in the power supply. Good Luck

at JVC Support Page , download owners manual , listed above , on page 35 , it appears you should press INPUT button and cycle thru TV / video 1 / video 2 / V2 component / and video .

depending what video input option you used to hook up your Xbox to , you should be able to figure it out from here.

Dish is probably using one of the A/V inputs and not a channel. trying the video input or A/V button on your TV remote or on the front of the TV.

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck

The lightning probably zapped the tuner in you set. If no signal is present the screen is muted (BLUE).This is a feature to prevent your seeing snow on the screen. Stargazer

this symptom is what we called vertical fold-over. vertical fold-over is characterised by a white horizontal bar on the bottom or top of the raster due to the concentration or compression of the trace lines. it an image is present, the bottom or top portion is fold over. this is caused by a vertical deflection current with poor linearity, which compresses the trace lines at the bottom or top of the screen. this symptom is is caused by a defective sawtooth wave genetator circuit, or improper biasing or defective feedback circuit of the vertical drive or vertical output transistor/ic. the negative feedback circuit in vertical deflection circuit compensates for the linearity of the trace portion of the sawtooth wave. a decrease in the capacitance of the sawtooth generator capacitor is usually the trouble. but if you do not understand anything what i have written here, better bring it to a qualified tv technician for your own safety also. good luck!

The mounting screws must be the correct metric size to avoid creating a safety hazard. Remind Currys that you have not received the hardware but also contact JVC to request the hardware. Before installing the TV, check to be sure the hardware is correct particularly with regard to length.
