Thats a CTC195 chassis, a very common one too. The High voltage transformer along with the horizontal output transistor is most likly bad.. Before you get the manual, have your freind measure the horizontal output transistor out of the circuit. If it is shorted , the flyback is bad also. Its no longer available. I have a ctc195 chassis but its not the projection release but the horizontal circuit is the same, just adds a few caps and hivoltage block for the CRTs. If I could find the link here I would give you a PDF of it. I just threw out a projectiuon set as well as a 32" TV because I could not get these parts. Good Luck PS Please dont forget to rate this thread.

SOURCE: RCA P52960 52" Projection TV. When the 5A 125V

It is an indication of shorted parts on the power supply.
Replacing the fuse alone can't solve the problem.
I've suspected that you have a short on the following parts (rectifier diode, regulator I.C.) on the power supply section but needs to check by a qualified technician to isolate the problem. It is quite technical and not diy.

If you unit is under warranty then send it to the nearest service center of your manufacturer then avail the warranty.They will fix it for you for free and/or a little charged only.

pls rate my help.

Thanks for using fixya.

Picture flickers every few minutes


There are several possibilities. This model is based on CRT (picture tube) technology, and has a high voltage circuit. This circuit consists of three heavy wires, one from the side of each picture tube (red, green and blue) going to a single connection block. There is another heavy wire from this to the high voltage transformer on one of the circuit boards.

First, unplug the set, and wait 20 minutes to make sure everything is cool and residual high voltage charge has drained away. Check the wires at the connection block to make sure they are not loose. There is usually some sort of retainer clip to lock the wires in place, make sure these are not broken or unlatched (sometimes they get brittle with heat and aging). Frequently these are covered with a thick layer of dust held on by electrostatic attraction; gently vacuum this off. If all looks good, plug in the set, and wait until it's dark outside. Turn on the set with the room lights off, and look at the high voltage parts. If you see a blue corona glow or sparking, that part has an insulation breakdown problem or a bad connection. It is normal to see an orange glow at the bottom of each picture tube, and you would also see the three colors of the picture coming out of the tops of the picture tube. WARNING: do not touch the interior of the set while it is on, especially not in the dark.

Another probable cause is a cracked solder connection on the power/deflection board (the one with the high voltage transformer on it). If the flickering is one color rather than white or a momentary darkening, the problem is in one picture tube circuit (yellow -> blue dropout; ->cyan -> red dropout; magenta -> green dropout). The picture tube circuit includes not only the high voltage (second anode) section, but also the picture tube drive connection on the base of the tube all the way back to the video processor and switching circuits.

Can dust build up on a picture tube's circuit board cause them to overheat and shut the tv down.


dust will not cause an issue like this in this type of set--RCA? it means a short of some type exists and the set shuts down or blanks the tubes--all you have described as far as appearance is normal.

RCA sets like this can be difficult to repair and also if you Google the model number you will see they have a lot of "problems".

Sound, but no picture


If before it was going rather bright red or a version of that--it is related to the circuit for the red picture tube this set uses---the tube itself or the circuit board that plugs onto the end of that tube.

If bright red, green or blue screen set will detect too much current being drawn and blank or turn tubes off; not likely a do it yourself repair and this set is prone to this and many other problems---Just Google the model number with "problems" and see what I mean.

The picture is blurry and looks 3-D.


Look on back where model number is, there should be a chassis number like ptk195

If it is a 195 I know what is wrong. That set (many versions) has a small board that provides power for the convergence circuit--it that board is there it will be easy fix.

attached photo of convergence problem.

LET ME KNOW IF PTK195 ON BACK OF SET AND if this information helped you rate this solution as very helpful as I do this here for free.

Hi Sandy, the problem with your TV is called "convergence". It can be a problem with the convergence board or more likely in this model in the power supply or deflection circuits. Unfortunately, troubleshooting by a technician is required.

My picture looks fine but i have no green or red color. Was watching tv and everything looked fine but the green and red just disappeared.


Remove the back cover and see if the red tube is on. May have a problem with the tube or just the tube circuit board.

NO HORIZONTAL DEFLECTION. THIS RUNS THE REST OF THE SET. POSSIBLE COMPONENT FAILURE/BAD CONNECTION

Picture in concave on all sides and blue and red are off


The shape of the picture indicates that the convergence circuit is not working properly. Generally speaking this occurs without making any sound at all. The popping you heard may have been a capacitor in the power supply. If the power line effected supplied the convergence circuit, repairing the supply should return the set to normal. If not, then the convergence ICs may be faulty. If you can solder, and are confortable working inside the set where potentially dangerous high voltages exist (even when unplugged), you may be able to repeir this yourself.

Let me know and I'll provide additional details and instructions.

Distorted picture


The RCA P52960 uses the PTK195 series chassis. There are 2 main boards at the bottom of the set and above the board on the right (when viewed from behind) is the convergence power supply board. This board usually has a big black IC on it, labeled STK730-010 and bolted to a metal heat sink. Chances are, that IC has burned out and stopped working. Replacing that IC should restore your convergence. If you do not have experience replacing IC's in projection sets, allow a qualified tech to handle it for you.
