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.

Samsung HL-P5063W makes a whining sound and then goes off


The most common failure in the DLP that makes a whining sound would be the color wheel. They cost about $135 + labor because I wouldn't advise changing it by yourself.

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.

Unplug the set, pull out the lamp module (not all the way - leave it on the track) and push it back in.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.

Whining noise


The problem i had was when i would play my tv. I had it hooked from my dish to the sony then the tv. When i played a dvd,cd or the tuner it didn't make that noise. It seems my video/audio 2 channel was going bad. I disconnected my rca jacks and used the optical audio connection. The noise stopped and i got a better quality sound.

hope this helps
