It could be a fan going bad or it could be an electronic problem I would advise to have some one look into it before it damaged the tv permanently.

Loud sound would be coming from defective color wheel that is mounted i light engine, next to lamp housing. Replacement of color wheel is required expertise/ experience and professional will do that for you in correct and in safe manner.
Contact local tv repair shop to get color wheel replaced in tv.
Thanks.

RCA HD50LPW42. Sound so loud it sounds like a jet engine coming from TV (very loud whining sound). I assume this is my color-wheel, but I'm not sure.Turns off when TV turns off.


You need a replacement color wheel or have yours rebuilt since the RCA color wheels are on nationwide back order. You can get your wheel rebuilt at the following link

Buzzing


If it is a buzzing noise, it is the Ballast for the lamp.
If it is more of a grinding sound, it is the Color Wheel motor.
Does it go away when you turn off the tv? If so, does it stop abruptly or does the sound tend to get softer (winding down noise)
If the noise stops abruptly it is probably the Ballast.
If the noise takes several seconds and seems to get softer until it stops about 30 sec later then it is the color wheel motor.

Help - dead TV


The power supply in this model was terrible about having bad capacitors. The bad capacitors in this unit will have the top of teh can bowed out and browned. A qualified technician should be able to repair or replace the power supply.
