The high pitched noise you have mentioned is definitely coming from the horizontal deflection circuit. Check the deflection circuits for any damaged capacitors on the deflection circuit. Cracked, leaky or swollen(at the top) if its electrolytic. SMD caps are more complicated. You should have a multimeter capable of measuring capacitance and equipped with a tweezer. Best thing would be just to replace all the caps on the deflection board. Should be around 15-20 of them.

    Did you try replacing the caps? If you want to get over with it quickly replacement deflection board should do the trick.

    Sorry for the delayed response. Its 6.30 here in India and I just woke up. The capacitors look like little cans with sometimes with a "+" at the top. Since you have accepted the thread you may not be able to post further comments on it. But I am not gonna leave you stranded. Send your further responses to vls_powerful2002@yahoo.co.in and I will see you through this.

No power and their is a beeping noise coming from the back of the tv.


The beeping is usually caused by failed HOT Transistor and also possibly the flyback. You can get the Flyback and HOT repair kit from www.tvrepairworld.com

My 60' RCA big screen won't turn on and it has a ticking noise coming from the back, like if it's a bomb


the ticking noise is a shorted horizontal output transistor which is loading the 140 source from the power supply

and its a good bet your flyback transformer is bad also

if its a ptk195
its repairable and the parts are available the transformer wil be a after market and if your going to try and repair it your self make sure you get a hr there a better transformer

Where can i get a flyback for a rca 52 projection tv m#p52937yx2? I read all day and it seems to be the fix? wont go on and has a clicking sound that persists untill you unplug it.


1.) RCA no longer sells this part--a company called ASTI makes a replacement for the RCA #250694---they call it #2086

2.) If you go to Ebay you will find seller "sewsales55" sells this replacement transformer for 19.95 plus shipping--type in search 250694 and you will see it--they sell lots of parts and give a 6 month warranty--fyi--If I was you I would check the HORZ output transistor--usually it is bad also---I have repaired dozens of these sets with this trouble-usually just the flyback transformer and the output transistor.

If you need help or have questions let me know.

I do this here for free so if this helps you take just a minute and give me a vote here.

RCA P52937 Flyback Transformer question


The lead going from the flyback to that other device is a voltage divider or splitter as they're incorrectly referred to... To remove the leads press down firmly, twist and then pull up...

No power


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.
