Question about RCA P52937 52" Rear Projection Television

2 Answers

No power when the TV is plugged in the only thing that happens is a chirping noise coming from the pack of the TV. The noise seems to come from a transformer although I suppose the problem could be the HV Block since that seems to be the big proble area for these TV's.

    It doesn't make a sqeeling noise it chirps, just a small chirp then a pause then a chirp and it continues to do this for as long as it is plugged in. It is a CTC195M26B Chassis, at least that is what is what the label says. The model is a P52937YX2, Do you still think it is the Flyback and and output transistor?

The P52937 uses the PTK195 series chassis. If the TV makes a squeeling noise the instant it is plugged in then unplug it immediately and do not plug it back in. I have seen this many, many times. The flyback (high voltage) transformer has shorted out and the extra current it was drawing has shorted out the horizontal output transistor, so the B+ supply is dead shorted and the power supply squeels as a result. This is very common in that chassis. The flyback and output transistor will have to be replaced by someone with experience in RCA projection TV's. The HV block in the PTK169 sets is the one known to be bad a lot - the block in the 195 is very reliable and I have never seen one of those bad.

    It could still be the flyback but it probably does not have a shorted transistor. This actually depends on whether the chirp is coming from the flyback transformer or from the switching power supply transformer. I would first need to determine if the main B+ from the power supply is always up and running or if it going up and down with the chirp sound. This does sound like one of the more complicated problems with that chassis, so the set should be looked at by someone experienced with the RCA 195 chassis.

RCA p46732ba projection TV no power.

This is a common problem and the set is in shutdown mode. It attempts to fire up three or four times (the chirp you hear) if it detects a fault it shuts down - the most likely cause is the HV (high voltage) block- caution working on it since HV is present - The repair generraly costs $200-400 P# 205064

Google your model # and HV block to see what I mean.

After pushing the power button on there a chirping noise coming from the back of the tv and doesn't turn on.

hi, the chirping noise is either the switch mode transformer or the flyback transformer, more likely the flyback as thomson built sets are infamous for them failing, nothing you can do you`ll have to call a tech to verify which has failed, not a major repair job, gl, video-tek

RCA 31" TV pakes high pitched chirping noise

Did you check the Horizontal Output transistor to see if it were shorted, and also check the MOSFET of the switching power supply.

No picture, no sound, just chirping noise coming from back

NO - - signal did nothing to the set... Sounds like a shorted HOT (horizontal output transistor) and the feedback your hearing (chirp) is on the horz. transformer as it tries repeatedly to startup... Don't allow it to do that for too long...

No picture or sound - TV makes chirping noise

The chirping sound is the power supply coming up then breaking down because there is a short somwhere in the high voltage. The most common fail in this area is the horizontal output is shorted ( 237470 ) but what cause this short could be simple cold solder joints or the High voltage transformer ( 239111 ) If you have noway to "ring" the flyback change both parts

TV makes chirping noise, won't turn on!

That usually means a problem in the start up or deflection circuits. Diode, Horizontal ouput or driver transformer. What Chassis is this set, and I will be ableto give you some better information. Rca , GE and phillips need to be diagnosedwith the chassis number. Let me know the chassis.

TV does not turn on. When plugged into an outlet makes a high pitch noise.

Your problem is a shorted horizontal output transistor C5148 located behind the highvoltage transformer on a heat sink with a clip over it and you can't see the number unless you remove the clip Has to be unsolded and solder in new. Also the highvoltage transformer must be replaced This is the big part with the large red wire coming out and going to the top of the picture tube. Must be unsoldered and replaced with original RCA not get a replacement It has several connections plus three wires to connect to it and I recommend using desoldering brad can get at Radio Shack 5 foot roll. Well as you can see it gets pretty involved. You can't get the parts from most distributors unless you have a business. If he tackles it and has a distributor the parts would run about $50 to $60 and a repairman average should be less than $200 and more than $150 hope this helps. Contact me for any questions you may have. I am more than willing to help.
