Question about Zenith R50W46 50" Rear Projection Television

4 Answers

Won't turn on...

When the power button is pushed, it makes a "chirping" sound (like a cricket).
No picture & no sound except for the "chirping"...
What might it be?
About how much will it cost me & how much SHOULD it cost me?
Is it even WORTH saving?

Not sure but I'm working on my wd57732 and have found the color wheel motor has a cermic shaft bearing and the chirp might be coming from this. It's like glass on glass. The color wheel must be spinning at hight RPMs before the light will come on.

I have the same (I think) problem. The "chirp" sound it makes is very faint though, the sound of pushing the power button on the front almost overwhelms it. Is the power light on red? My power light is on red, and the only way to turn it off is to unplug the TV.

I have no pic or sound except a chirping noise , sounds like a cricket , LOL , timer light stays red , there was a odor , like a burnt smell


Hello. The chirping probably indicates a shorted transistor or diode, and the burnt smell usually indicates a blown capacitor or a burnt resistor, or multiple damaged parts. I would have to see the TV to be of any further assistance. Sorry I couldn't be more helpful. Good luck.

My old 32 inch rca f32665 stopped working as we were watching it. no picture or sound and there is a sound coming from the back where the power cord goes in that sounds exactly like a cricket only its a...


The usual cause is a shorted horizontal output transistor. The way this chassis is designed, the supply makes 140 volts which is always on and applied to the transistor. The heavy load on the power supply causes it to make that chirping sound as it keeps trying to start, then shuts down right away.

The h-out is Q14401, RCA part number 237470. A 2SC5148 can replace it.

Hello bradahman,

The chirping sound is either a shorted Horizontal Output Transistor / Power FET (whichever one is used in this case) or the IHVT (Flyback Transformer) has developed a short in its windings. In ether case both components will have to be replaced. I would suggest you have a qualified TV technician come over and troubleshoot the problem and give you an estimate on the repair.

I hope this helps,

Thank you,

u have a short on one of the secondary voltages from the power supply. commonly a bad diode.
the chirp is the supply attempting to start into a short.
