The high voltage transformer is going more than likely.
the picture is affected because the flyback transformer drives the horizontal deflection circuit as well

Emerson EWC20D3 20 in. TV/DVD Combo what is that loud whining noise from the back


What happens in this case is a small transformer or the high voltage transformer vibrate hard enough to make that sound--not loose or bad but can cause the vibration.

I have seen in customer's homes where it was loud enough to chase cats right out of the room even in a large room.

Two ways to deal with this----with the set apart locate the part by ear or even probing with a plastic tool---when you press close to it, the sound will diminish or go away.

Believe it or not (in our shop) once located we use a hot glue gun to take the sound away---

usually if very loud it is the high voltage transformer on the main TV board (see photo of a typical one) not on the black part but on the iron like (it is a different material) core that looks like a U bolt.

it can irritate but poses no danger.

Optoma ep716 continuous loud vibration noise when turned on.


the fan motor could be failing. turn it on with the top off. if one of the fans is moving slower, that'd be the one. since this is a dlp projector, the colorwheel motor berings might be on their way out as well. both need replacement.

Loud popping noise


The 23" CRT set may have a high voltage breakdown in the flyback transformer or focus divider. Take the back off and operate the set in a dark room. Look for anything that has a blue glow around it or sparks flying when the pop occurs. I won't guarantee this will find your problem, but it is definitive if you see these!

I once had a set with these symptoms. I stopped the blue glow and arcing by covering the focus divider with epoxy. It worked for a couple of months before the divider literally broke apart.

Sound at power on


The sound you are hearing is the degausing coil which will vibrate for a second when the tv is turned on. This part demagnetizes the picture tube and this sound is really quite normal. Depending on the position of this coil it may vibrate against the front cabinet of the tv and may sound loud at times. If this really bothers you then you need to have the rear cover removed and have it repositioned a bit do it won't vibrate so loudly. Or you can enjoy the buzz for the short time it happens and not worry about it.

Very loud fan or vibration noise


Listen from the back of the TV and locate the source of the noise. There may be fan with a bad bearing. The noise will lead you to it.
