"High Pitch Squealing" from my tv.

I have a Sony FD Trinitron Wega, model #kv-36fv16 and it just recently started squealing. After about 5-6 hours of continuous operation it starts this high pitch noise, so I muted the tv to see if it was the station but not that lucky. Is the tube going out and if so, is it worth spending the money to have it repaired?

    Hmmm.....so how much do you think it would cost to have this repaired?

    But it was helpful, it didn't fix anything yet. I'm still trying to get information, wouldn't you do the same? I do appreciate your time and help with this.

    you should not have rated me if you were not done asking me questions , and that rating hurts our rating by -.01% as only a fixya helps

    I will have to do some research on your tv and the part that is making the noise

    if your still wanting help then you should wait to rate my help since we were not done yet , and to fix it either I would have to physically fix it or you would have to be able to with the info i give you , but this will not be fixed untill the part is replaced , and if i can't hear the part that is doing it or if you can't tell me what part is making the noise then i cannot tell you how much the part will cost ,also repair shops vary in thier repair prices so that would be hard to say what they would exactly charge ( ecspecialy these days )you would have to call one to see if they will give you an estamate on the repair.

    coils can range from $30 to $350 depending on if the coil can be replaced or if the whole board has to be replaced because the tv company may only sell the board and not the part , transformers can range from $80 to $350 depending on if the whole board has to be replaced or if the transformer only is available. and to know how much the part will be most of the time you would have to have an account with the tv company to get the part and the price of the replacement.

    but after a while some parts are no longer available , so some research to find out if they are still selling the part will need to be done and if they don't then more research will need to be done to find a place that hopefully does sell the part or parts needed.

    and if that don't work then some more research will need to be done to see if another part can be used from another board on another type of tv (same brand )

    can you open the tv set?

    can you tell what part is making the noise?

    can you give me the identification numbers on the part that is making the noise?

    sometimes the noise can be stopped by plastic zip ties and a hot glue gun , (if applicable)or possible to do so.( depends on the part)( coil or transformer)(small coil or large , small transformer or large)

We own 2 Sony TVs. FD Trinitron Wega KV-27FV310 and LCD Bravia KDL 40S4100. Both have now lost 1/2 a screen. Top 1/2 on the Wega and left 1/2 on the Bravia. Our son plays XBox 360 on them. What i


On the WEGA the panel control module and possibly the left side planer board is done for. On the other sounds like the planer board on the dark side is done a well.
Get your son a Gaming type monitor cause this will continue to happen due to the higher refresh rates demanded on the gaming software.

Sony WEGA KV-36FS16


Actually, the Horizontal Lin Coil has been known to cause this. You can sometimes confirm this by lightly touching it with a plastic rod or something non conductive. If it is the culprit, the ringing will stop. Usually you cannot dampen the ringing, You must replace the coil to fix it if it turns out to be the problem.
Hope this help,
