Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

1 Answer

High pitched whine

All of a sudden my D52w20 (which has not been used often) intermittantly while watching TV or playing X box starts making a really loud high pitched whine. If I turn it on/off several times sometimes it will stop. What's strange is when it's doing it and I turn it off and back on, the noise does not start until the picture appears, and sometimes the noise does not come back on at all, or at a different pitch or noise level.It seems to happen more often when the TV has been on for a while. Otherwise the unit works just fine. I would really like to repair this myself......Thanks for any advice.

Check the color wheel and any fans running on the unit. The color wheels make a high pitch whin right before they quit as well as the cooling fans.

Youre going to need the deflection board as the high pitched whine if it sounds like a short chirp each time the power indicator lights for the 3 times is caused by a surge taking out numerous components on the deflection board. You can get your board rebuilt through www.tvrepairworld.com which is fully guaranteed for 6 months. New replacement boards are not available anylonger for the ITC222

High pitched whine/sometimes TV won't turn on


The power supply on this model will whine when it is shorted or overloaded - the set would have to be brought in to determine exact cause.

High pitch shrill when input device not DVI


use of silicon or superglue on a coil next to the flyback that solved the problem in a similar model RPTV. Easy fixes first
