Question about RCA D52W19 52" Rear Projection Television

1 Answer

I have an RCA P61926 62" Rear Projection. My high voltage splitter is arcing and needs to be replaced. Can I just unhook the anode leads to it or do I have to discharge each CRT lead with a high voltage probe first?

    Thanks for your help on that. I replaced the splitter and the TV works fine, but intermittently. I have a problem with the convergence going haywire now. Sometimes the TV will work fine for hours, then the next time I turn it on the convergence will be way out of whack and I'll get a pincushion effect on the bottom, sometimes the top. I think it's a capacitor in the convergence circuit failing to hold a charge, or possibly a cold solder joint. It's going to be fun locating the culprit since I don't have the schematic for it.

    Okay Crickett, you've helped me before, I could use your advice again. I replaced my HV Splitter and the TV was working fine for about a month, now there's a glitches and a popping sound coming from the new part. Is it possible that the HV Tripler is defective and putting out too much voltage to the HV Splitter causing it to go bad prematurely, or do you think I just received a defective part? At any rate, I'm going to call Suburban Electronics and see if I can get a replacement. I'm just not sure if I should go ahead and replace the Tripler as well.

    Most likely in that model, it's Cold Solder Joints.. A dried out capacitor will not create those issues. Happy soldering!!!!!!!!!!!!!!!

    You probably got an after-market in which they don't hold up as well. If it's in an RCA box with there part number you just got a bad one. Any set will not let HV go anywhere except what it's suppose to have. They will go into shutdown until the problem is fixed. so to answer your question about HV, the answer is NO. Make sure you clean the anode leads off with alcohol before putting them back into the splitter. I have had the anode cups dry out, crack etc...

My rca p52926 picture cuts in and out


If model number is correct (on rear of set in small letters it should be a PTK 195 chassis) you have a high voltage lead somewhere that is arcing.

This set did have issues with the High Voltage transformer failing and also that High Voltage (well over 10,000 volts) gets distributed to each of the 3 picture tubes this model uses.

Sometimes the lead where it connects to one of the tubes begins to arc---it is coated with white silcone to prevent this.

If arcing around the entry point to any of the tubes sooner or later it will take the set down--destroy parts that are currently ok.

Usually we locate this by turning set on with back off and looking and listening when set is turned on---If a frying or pop is heard up above the main boards--one of the entry points (called the 2nd Anode) is arcing.

I have seen them arc hard enough and long enough to actually crack and break the glass wall of the picture tube.

May be the high voltage lead(s) have popped off of one of the pix tubes...the flyback(HV) transformer may be defective....you can remove the rear cover and look to see what is arcing..be very careful as the voltage may be as high as 25000 Volts...if one of the anode caps has popped off, then you will first need to use an insulated screwdriver that is grounded to the chassis through one of those alligator clip jumper leads..this process will discharge the unit to make it safe to work on the HV components...then you will need to pop the anode cap back onto the tube making sure it has a good tight fit...if the problem is elsewhere, you will need to call the serviceman for repairs

AKAI PT5492S - Makes a ticking noise,black


This usually is indicative of the EXTREMELY HIGH VOLTAGE anode connection somewhere between the flyback transformer and one or more of the crt picture tubes or the splitter. Being that this circuit has a running voltage potential of over 30,000 volts if you are not familiar with these YOU CAN BE KILLED messing with it!!! What happens is that there is a breakdown of insulation over time usually from dirt or other environmental contamination. Usually a good cleaning and replacing the HV anode wire that has failed. (hint) it will be the one that the "ticking noise" is coming from. The ticking noise is actually the high voltage arcing to the chassis/ground.

Be careful!!!!

Tv went off and won't come back on.


the arcing sound is some kind of high voltage leak, which will shut down the tv. pull the speaker grill off and the access board, look at the 3 picture tubes, turn the set on you will see where the leak is, it's usually the high voltage splitter, which has a high voltage wire going into it and 3 high voltage wires coming out going to the picture tubes, if it arcs from the splitter you need to change it, if it arcs from one of the picture tube wires you need to pull the tube out and fix the high voltage leak, and possibly a cooling fluid leak caused it, not an easy reapir, you probably need a repairman.

CRT Question


Maybe, be safe. Run a wire with an alligator clip from the screwdriver shaft to the chassis ground while popping the anode off.

RCA projection P46732BA no power and arcing sound


The High Voltage Splitter is the cause of this and replacing it should fix the problem. Their should not be a shock hazard once power is diconnected. But just incase, ground each of the anode leads from the crts to ground. That should take care of any HV charge from the CRTS. Do make a note of which wire went went where, that is important. When you get the new HV Splitter, you will need to transfer the small board that is mounted on the old Splitter. Again, be aware of where the wires hook up to it and you will be fine.
Hope this helps,

My 52 inch rca tv has sound but the picture keeps popping on and off .what can be wrong with it?


2 THINGS THAT USUALLY CAUSE THIS PROBLEM IS
1) THERE IS AN ARC FROM ONE OF THE PICTURE TUBE ANODE LEADS--15.00-- THE TUBES ARE STILL GOOD , JUST THE LEAD IS BAD---NOT EASY TO REPLACE ,,YOU HAVE TO CUT THE OLD ONE OUT AND REPLACE USING SEALANT ....
2) A PART CALLLED A HIGH VOLTAGE BLOCK--75.00--THIS PART TAKES HV FROM A FLYBACK TRANSFORMER ,,,SPLITS THE VOLTAGE TO GO TO THE 3 PICTURE TUBES
KEEP IN MIND ,,IF YOU HEAR A POP--IT'S USUALLY A HIGH VOLTAGE ARCING TO SOME METAL--YOU ARE BETTER NOT PLAYING THE TV

52 in RCA


The T.V. has no lamp, it has 3 guns red,blue,& green. Unplug the lead that goes to the high voltage splitter(make sure t.v. is unplug). Then turn the t.v. back on if you hear the H.V. lead making a hissing sound continuously most likely the h.v. block needs to be replaced. Follow the lead from the flyback to the h.v. splitter, this will be the lead that unplugs at the splitter.
