Re: SQUEALING NOISE AND SET TURNING OFF
The squealing noise is a defective color wheel. When the color wheel does not get up to speed (or stay up to speed) the set will shut down with the blinking you describe. You need to replace your color wheel or have a tv shop replace your color wheel.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

I have been having the same problem with the alternator belt squealing, most noticeably, when using the heater fan , accelerating, turning the headlights on. I have a 1997 Toyota Tercel CE 1.5L 4cyl with no A/C. I just tightened the belt tight enough that there is no give to the belt and it does not squeal anymore.
I also used a Goodyear Gatorback from Napa belt which seems to be nice and quiet when tight enough.
Most likely need to replace you accessory drive belt. However, before you do that make sure the tensioner is bringing adequate pressure to bear on the belt. The squealing is probably the side of the belt slipping in the metal drive pulleys.
Sounds like you might have a loose are worn fan belt. Specially if this is a V belt. With the hood up have someone turn the air conditioner on and watched the compressor clutch if it stops turning you might have a bad compressor. If it keeps turning in the squealing just goes away, you might just have a loose belt. Good luck.
yes...your engine belt is little bit lose that's y its causing noise...and hope when u speed up..it will stop squealing ..right?? so just tight your engine belt little bit and it will solve your problem in a min...take care n have a safe journey...n also if it help...rate it plz
The noise is most likely the serpentine belt. Check it's condition and that of the belt tensioner. It sounds like the belt is slipping, causing the squealing noise u describe. As the belt warms up, it's getting a better 'grip' and the noise stops. Turning on the heat also turns on the a/c in newer cars, this added drag on the belt (one more component to turn, the a/c compressor) would explain why it happens when u turn on the heat. Is the belt original? If yes, it's time to change it, and check the belt tensioner to make sure it's doing it's job of keeping the belt snug on all the pulleys. Let me know how u make out.
The whine or squealing you hear is either the color wheel or fan. To determine which, when the noise is heard from the set, turn it off and listen carefully. If squealing stops immediately then Tthe fault is the color wheel, not the fan. And sounds like that are generally the color wheel.
A new color wheel is Samsung p/n# BP96-00250A for this model. Vance Baldwin carries them for $97.20 plus shipping. https://www.vancebaldwin.com
