check the belt tensioner.

sorry but sony don't have color wheel , if u have a high pitched noise may be a fan , now the question is is this problem only when u first turn on the tv or is there all the time , if is there all the time fan , but if only when you turn on tv may be u need to replace lamp , because the noise would be from the ballast trying to turn on the lamp

This tv is under five years old?Yes,it is worth fixing.Over five,i would compare the prices for a new LCD tv and the quote priced from the Tv Tech.for the old tv.This tv have high voltage problems around the Deflection circuitries area.Could be any things burn in this area.The high pitched whine sound,i'm sure it is from the FBT-the high voltages flyback transformer,high voltages current have no where to go.Must hire a tv tech. to troubleshoots and replace parts on the Deflection circuitries area.Also the FBT could be dead too,because HV Current bounces back forth and have no where else to go.The prices to troubleshoot unknown problems is about $400 bucks and plus cost of replacement of parts.

Check the all the large capacitors or coils

Hello randapaint,

This might be from the IHVT (Integrated High Voltage Transformer), or more specifically a short in the IHVT causing it to arc, producing the high pitched whine, you are hearing. Take the back off of the TV and try to detect where the sound is coming from, more then likely you will notice it coming from the section that contains a large component with a large red cable coming from it, to the top of the CRT (picture tube). Replace the IHVT (with the exact same model) if it is bad.

I hope this helps,

Thank you,

If it weren't for the high pitch whining noise. I would say it probably is an internal fuse inside the chasis. It is rated at 1.5 to 2.0 amps. With the whining noise it sounds like a trouble shooting bench
job. Problems occur when a electrical/electronics device is turned on and turned off. Inrush voltage,
when it is turned on, can go up to three times more than normal. This also happens at turn off. Solid state components usually fail at this time. I don't feel that this is a problem that can be fixed in the home.---BBB

Ok maybe this may help .... there is a coil LL08 I believe... somtimes it creates a high pitch whine like you describe.. its stands up on the deflection board..it basicaly a large coil of copper wire....you can take silcon and put on the coil...in effect damping the ocillations...hope that might help
