    I thought the model is HLM617W

    The noise does stop as soon as set is turned off. Also, no lights are blinking on front of set to indicate any lamp problem. I have replaced the lamp a year ago.



    Thanks

    If your refering to the bottom left as viewed from the front of the set it can be the cooling fan for the lamp. Is the whinning constant ? Does it continue after shutting unit off ? If so that would be indicating the fan as the cooling fan will continue to run after the set is shut down. If it stops whinning at shut down that would lead me to suspect the color wheel being in the early stages of bearing failure.

    Its the color wheel if it stops. Thats located right in front of the lamp after the small glass panel. Its under the ribbed section.

When The TV is running it makes a high pitched whinning that seems to be coming from the projector


its a bad color wheel and you may be able to replace it. You Tube has videos for this.

This tv is under five years old?Yes,it is worth fixing.Over five,i would compare the prices for a new LCD tv and the quote priced from the Tv Tech.for the old tv.This tv have high voltage problems around the Deflection circuitries area.Could be any things burn in this area.The high pitched whine sound,i'm sure it is from the FBT-the high voltages flyback transformer,high voltages current have no where to go.Must hire a tv tech. to troubleshoots and replace parts on the Deflection circuitries area.Also the FBT could be dead too,because HV Current bounces back forth and have no where else to go.The prices to troubleshoot unknown problems is about $400 bucks and plus cost of replacement of parts.

RCA 50" - Convergence problem and now "Popping" + no picture


The high pitch popping that you are hearing is arcing in the high voltage circuit. I would not suggest a repair on a set that is this old. Convergence repair plus a high voltage problem could run around $500-$600. But it is your call on the repair, I can only advise.

I hope this helps you.

RCA HD61LPW42 - no picture


I haven't worked on an RCA DLP but have on Samsung DLP, based on your description it sounds like the color wheel is bad. Take the back off and turn on TV make sure its not a fan making the noise ,but most likely its the "wheel" it is inside the light engine probably right next to where the lamp is plugged in. If the whine comes from this area definitely the wheel.
