Question about RCA D52W19 52" Rear Projection Television

1 Answer

High Pitch Noise

Initially turning on the TV, there is no issue. After watching it for a while, there is a faint high pitch noise. It is not loud, but enough to annoy me to turning it off. I barely watch the TV any more because of it.

High pitch noise when tv warms up

High pitch noise is created mostly by a Coil or a transformer,is not easy finding the source if you are not familiar with this type of coil since there many sizes and shapes,the set needs to be on while trying to find wich part is doing it SO if you dont know where and how better call a Technician and you will be safe.
