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!

How do I determine if it a power failure or if it is a faulty SC board (TNPA5335)?


That does nost sound normal. I would take a look at the output of the power supply. Look at your electrolytic capacitors on the power supply board. Do they look like the top of them has popped up? If so you can get replacement capacitor kits from www.lcdalternatives.com

How do i watch my tv with a broken remote


You can buy a universal remote and program it to work with your TV. I have always had good luck with RCA universal remotes. You can also program the remote to run your cable/sat box and your DVD/blue ray player. You could also go to the web site of the company that made the TV and order a new remote. This would be more expensive but the remote would run all the funcitions while the universal may not.

How could I connect a Daewoo 42sm TV?, I can't afford cable so I use a converter box(analog to digital w/rabbit antenna)on my other TV and I was given this Daewoo TV and would like to watch it;please


If your converter box only has RF outpit connectors "F" type screw on it looks like this my be more of a monitor then tv.I took a quick look at the manual and didn't see any RF inputs so it appears it doesn't have tuners built in Looks like you'll need a box that has RCA output connectors.or others that will match what the monitor has on it for input types

Devant ER 31951D remote


Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Pull up older posts. If the remote control is found OK; check and replace the infra-red sensor inside the TV. Contact any service technician.
