Hello,

try to re soldered all the connections inside. there some loss connections. during the examining try to look in the some resistors that causing the noise. examine also the regulator in the vertical and horizontal circuit board.

That is the oscillation sound comes from the relay,cannot continue because of protection mode,by the system.The problem is not in the convergence ,because you cannot see picture in convergence problem you ca see picture,but blotted colors,.. Your tv parts is ok.only the solder joint is crack or cold thats why function abnormally,goes off and goes on, due to the voltage trap, when voltage is there the solder is hot and connect the parts joint, when voltage extremely hot, due to prolong use it will disconnect the solder joint parts thats why you cannot see picture..its need to reheat the solder joint of all parts affected....power supply section ,,horizontal section,vertical section ..and to microprocessor ic section including jungle ic..
find a tv technician to do the works .in order to avoid high voltage shock this not cost too much because only reheating works....

    You power on your RCA rear projection TV. It takes extra long to turn on. Lots of
    clicking and a few power cycles? Your TV is trying a few times to get that
    pesky lamp going. Finally, the process ends with the dreaded three blinking
    lights. Your lamp is probably burned out. You’ve got a replacement lamp, right?























    First, sometimes you can stretch a little more life out of a tempermental,
    but not completely dead lamp. I’ve found that sometimes if I remove the lamp
    and put it back in, it’ll work. I’ve also found that colder temperatures can
    cause a failure, even temporarily. So don’t give up on it right away,
    especially if you don’t have a replacement. Wait a while (especially if that
    allows the room to warm up some) and try again. Or, pull the lamp out and put
    it back in.

    If it's a PTK 195 check the horizontal output transistor and if its bad, replace it and the flyback.Known issue with these RCA sets.

The clicking you are hearing is the main power relay that is truning on then being told to shutdown. This powerup attempt will occur three times before the electronics give up and leave the set in the "protect" mode. There can be a number of reasons for the set to behave this way. It can be anything from a bad connection inside that has changed the circuit characteristics enough to cause the failure to a defective part. Many sets will provide a code that helps to isolate the problem circuit. Does the power or standby light blink? If so is it a repeated count? Please post that number here.

Are you planning on repairing this yourself? If you are unsure, you should get a detailed repair estimate and report the results here. We can then help to decide whether or not the repair is worth it. Or we can walk you through the troubleshooting procedure and locate the exact problem.

Let me know what you choose.

    The RCA part number is 239111 and costs $68.99 from tritronicsinc.com



    Hope this helps.

    FIrst of all, this is a CRT based projection set. There is no lamp!!

    If you can solder, also check for poor solder connections on the main board around the flyback. Resolder any that appear to be grainy or have rings. That may be the only problem.



    Keep us posted.

I would suggest to start checking the B+ at IC U14101 located in the power supply.
If the B+ is present at the output and getting to the flyback transformer, you could have a defective flyback transformer or the voltage tripler could also be defective. If you have audio, the tripler could be the defective part.
NOTE: Please Be very careful when working around high voltage areas.
Let me know if you need further assistance.

I could be caused by overuse,when overused it creates heat and it might have burnt small parts inside. take it to your local RCA repair shop and have it checked...

Could be the flyback, or could be some resistor, capacitor are faulty, do check the part on the convergence module and check for any one of this mentioned..

Dir TV projection Techcions, I own RCA Model:P52937 Chassis No.PTK195M26B. After a big flood here in Chicago, my basement got flooded and my projection TV was in water up to 1 foot. Befor I turned it on, I dreid it out perfectly, then, I turned it on, and a couple components from the power supply got burned up to the point where I am not able to read the part numbers that are on it. I was wondering if you have this kind of chassis and model service manual for this projection TV, or conponet part number i location 101 on mother boatd power supply. Thank you in advance, Darius If you prefeer, you may call my cell phone: 773-875-3926
