Re: No Power and beeping noise in circuitry

Had a 51" rca rear projection donated to myself. While off and power button pressed there was a clicking noise from the front of the unit. Rear cover was removed and it could be observed that the hv splitter had a crack in the casing and the power was arcing out of the splitter. I purchased a $72 dollar hv splitter, i read that the $20-$30 dollar one would break within a year, and the unit powered up no problems.

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.

Screen suddenly turned off, makes an odd high pitched noise when it tries to turn back on. power button flashes orange


Sounds like there is a power problem if the neutral (return) wire on the power supply has become high impedance (or even disconnected) then you will get a high pitched sound coming from the TV PSU also the voltage that is presented will not be 240V which will give you the same problem.

The orange power button means standby if you fix the PSU then the TV might work again but it may have been damaged by the PSU.

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.

TV making high pitch sound


Hi, There are usually 1 or 2 fans inside the TV's. Could be worn bearings, or fan blade interference. Sorry, without my electric ear working, I can only guess.
