    Thanks for the help accordianman. Is this common? Is there anything I can do to try and make the sound stop? It's a very loud noise. When people are in the room, they jump if they aren't used to it...

    It's been on the stand for several's secure as far as I can tell. It sits on a Bell'O stand which is made of tempered glass. Only makes the sound when the TV is on. It's annoying!!!!!

    [B]I found a solution to the sound problem, which was causing popping and static sound from the speakers.[/B] This was also shutting down the audio after watching TV for some time. I place a heat sink on IC 987 part number stv8258DSX. This IC controls the sound and is overheating. The cause is unknown to me. Its easy to place a heat sink. Direction: cut the heat sink to size allowing room for a nylon nut. make as tall as possible. drill hole in center, but drilling only to its center, not through it.. Use nylon screw and nut (plastic). Insert the screw through the hole in the grill cover metal and than thread the nut to it. place the heat sink on top of the IC and place the grill cover back on aligning screw in the hole. (Don't forget to use thermo compound between the heat sink and IC). pull up on the screw while turning clockwise to tighten. I left the TV playing all night to the next morning and sound remain normal. I even turn on SRS sound mode.

Any other symptoms? You may be just hearing the occasional sound of static being bled off, or, if the set is not working properly, the sound of the high voltage section trying to compensate...accordianman

I would guess you have a High Voltage Leak at the Anode Lead Cap where it Mounts to the CRT. This is not a area to mess with You are better off calling a professional to fix it. It may be a little difficult to confirm if it is a intermittent problem.

Sony grand wega kf-50we610 red lamp light blinking

The red light means that the prjection bulb needs to be replaced. They ony last about two years depending on hours of use. The low popping sounds as well as fan noise is normal for the Sony projection TV. You can Google the owners manual by entering the brand,model etc. and ask for the owner's manual. I had to go to several sites but eventually found it.

Loud poping noise

It sounds like the popping noise you heard was a capacitor blowing its top somewhere in the tv. Sorry I cannot be more specific but if you manage to find out where this cap has gone also check any resistors near it as they can be also damaged. If you cant do this call out a competant technician. Good luck.
