Question about RCA 32V420T 32" TV

1 Answer

32" RCA when plugged in snaps an arcs

TV does not need to be on for this to happen. Woke up at 4am to the sound of popping and arcing- the TV was off at the time, probabley lucked out that I didn't burn the house down with family in it. Is this something I can handle? I'm a mechanic, and a so-so handy man. Could this be an easy fix or should I throw it on the garbage heap? Thanks

Normally an arc or snap like that is coming from the anode cap that attaches to the top center of the crt. The voltage there is upwards of 25k so be VERY careful if you're going to inspect this for any faults. If it is the cap leaking unplug the set and take a piece of wire attached to a screw driver with the other end of the wire attached to the grounding cable around the outer edge of the crt. Gently undo the cap from the crt and allow the blade to sit in the well for a period of time to discharge the crt completely.
Next get some HV putty, sold at most electronics distributors like Mouser and form a small ring with it. Place it around the well hole in the crt and replace the anode cap pressing firmly to seal the edges of the cap to the crt. With the back still off plug the unit in and see if that's cured the problem.

    That's about it... That should take care of it.... The discharge, although alarming isn't really a fire hazzard if it's from the anode looking for ground, but it can damage the FBT after awhile.

    Good Luck!

I Have A 1998 RCA Home Theatre TV Sound Works But No Picture And There Is A Snapping Sound And Light Or Ark Flashing Happening Inside


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

My rca model f36669 makes a popping sound and cuts off and back on


That's hi voltage arcing. Dangerous condition were a component has broken down and is arcing causing the power supply to 'crowbar' or go into over current protection mode. Call a TV repair pro for an estimate to see if you want to keep the set.

Arc in projection TV

RCA P52754AT POPPING SOUNDS. COLOR FLICKERS AND


It sounds like your high voltage block is arcing and causing the TV to go into protection shutdown temporarily. If that's the case, you'll most likely need to replace that HVB.
The other thing it could be if you're hearing "popping" (snapping ?), is that one of the CRTs could be arcing to ground, maybe the green one since you're getting too much green.
Good luck.

Heard a pop like a bulb blowing and can only get the sound. it makes a crackling noise when we turn it on.


It could have a arcing Hv Block or a something arcing on the Deflection Board. If the crackling noise is louder in the rear of the set, the Deflection Board is probably the cause. You can usually confirm by removing the lower back cabinet and observing the board on the left side. If you see any arcing at all, the board needs replacing. You can call Encompass Elect. for ordering the board at 1800-638-3328.
I hope this helps,

RCA PROBLEMS


two common problems with RCA TV's. It sounds like your flyback is going on you. There is probably a hole and it is arcing off a cap/ or something. You can order a new one or you can try and find where it is arcing by taking the back and looking at it in the dark to see where the arc is coming from. If you can find it try using a plastic epoxy to fill the hole

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock. Be careful !!! Stargazer

I would guess the popping/cracking goes away when the picture is present. Sounds like a high voltage arc either withing the tube or due to a cracked component in the high voltage circuit. If it's the tube, then the question is: how old is the set and is it worth it to sink $$$ into it as opposed to putting the same into another unit. If it is a defective component, that's much easier/cheaper to repair. Again, age of the set, etc. I hope this helps; definitly a repair for a pro.
