Hi Guys,

I have a Philips 109cm Rear Projection TV with Reversal Perplex glass. (manufact in Feb 1997)

It has an issue..

When I first turn it on.. I can hear a medium pitch/hover noise coming from possibly the rear of it. It's not super loud.. but for the first 10 to 15 minutes you can hear it well (even if you turn the TV off from the remote).. after 10 to 15 minutes the pitch noise dies down.. if you put the volume up enough you can override the noise with the TV sound.

It stays at the same rate until you manually turn the TV off.

What could it be?
