Will this work to degauss a CRT TV?

Question

I have an old CRT thats about 26". There is discoloration on the bottom left corner and I was wondering if this would fix it (http://bestofferbuy.com/TV-CRT-Monitor-Picture-Tube-Degaussing-Coil-Repair-Screen-/-Degausser-p-17986.html?currency=USD&utm_source=gbase&utm_medium=cse&utm_campaign=gbase). I am curious because a degaussing wand online other places is around $40 while this is about $17. Could anybody tell me if this will work for a 26" inch crt television? This is just an old tv and I was just curious as how to fix it myself.

Answer 1

A 110V-220V adapter (transformer) would cost more than the $23 differential between the $17 220V de-gausser and the $40 ones you've seen. It may be the de-gaussing circuit in the TV needs fixed. The usual thing that goes wrong is that the relay dies and needs replacing which is even cheaper to fix than $17.

Answer 2

Everywhere you place that refrigerator magnet on the crt screen will leave a discolored splotch. Magnets do not degauss, they magnetize, which is the problem you have already. If the degausser doesn't fully clean up the splotches, at least it will fade them. It is possible that mounting hardware on the crt was been magnetized, depending on how strong the offending magnet was in the first place. It could have been one of the strong magnets inside a power screwdriver- those things are strong- or a speaker placed too close to the tv. Be very careful if you work inside the TV cabinet. The neck of the CRT is delicate and on it is a configuration of magnets that trap ions out of the electron beam. You don't want to degauss them. Be sure to unplug the TV if you open it up. There is a lot of power in there.

Answer 3

Before you buy a CRT degausser, where are the speakers located? It is possible that the speaker's magnet is causing the problem. If so the degausser will not solve the problem until shielding around the speaker is added. By the way the degausser on the website requires 220 Volts ac. You will need an adapter to convert 120 volts to 220 volts in order to use this degausser.
