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.

What are the fuel injector wire colors for a ford escape 2008 3.0L v6 4wheel drive?


Okay, you know each injector has a power wire, and a ground wire that goes into the pcm? All of the power wires to all six injectors is a green wire with a red stripe.

The ground wire colors are as follows:
inj 1: green wire/blue stripe.
Inj 2: gray wire/yellow stripe
Inj 3: violet wire/gray stripe
Inj 4: yellow wire/orange stripe
Inj 5: brown wire
Inj 6: green wire/white stripe

I should note that the wiring diagram I am looking at shows this diagram as from a 2008 model manufactured during 2nd quarter of the year 2008. If your injector wire colors are different than as listed above, there may have been production changes during the year. But the power wires to all six injectors would still have the same color wire. You could figure it out that way: in other words, looking at the injector harness, same wire color to all six is the power wire, all the odd colors are the ground wire for that injector. Hope this makes sense to you. Good luck.

My Tv started with flashing red/orange colors. Then later the screen turned red/orange and the TV shut off. When I attempt to turn it on again, the screen stayes red for a few minutes then shuts off.


The problem based on the model number is in or around the red picture tube---the bright red screen causes the set to draw too much current and the shutdown circuit detects this and turns set off--self protection.

Each picture tube (3) has a IC chip on the board connected to it--shorted chip or bad picture tube.

Shop repair in most cases.

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".

Most wiring now is standard colors....red=ignition(goes to a switched power source...Yellow=battery...goes to a hot all the time(even with key off)...black=ground...white=left front speaker positive...white w/blk stripe=left front speaker negative...gray=right front spkr +...gray/ blk=right front spkr - ...green=rear left +....green/blk rear left - ...violet=right rear +...violet/blk= right rear - ...light blue or blue with a stripe is the remote turn on lead either for an amplifier or power antenna...some radios have an orange/ with white stripe that connects to your parking light dimmer circuit to dim the radio light with the dash lights....and then you should have the antenna plug and possibly rca outputs that go to an external amp

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.

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.

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.

NO PICTURE


there is a broken conductor strip or broken solder joint on the circuit board near the power input jack. do this: 1.) disconnect tv and open panel to expose circuit board. 2.) using a flashlight and magnifying glass, look carefully for this broken solder strip or solder joint. Flex board slightly if necessary to aid in finding the break. 3.) repair it using solder iron and flux solder and scratch copper conductor slightly to aid in "wetting" the solder fix.
