Magnavox TV - Colors off after hooking up DVD player

tvwatcher · Guest

Last three questions before I go buy a degausser coil (I promise), in my case the colors are off over the entire screen, not just in one area. Is this typical for the colors to be off over the entire screen when the shadow mask becomes magnetized?

I mentioned earlier my Mom had the cable box sitting on top the TV which I'm sure contains some kind of step down tranformer. Is the magnetic field from a small transformer enough to magnetize the shadow mask entirely?

Also, remember the cable box slid off the TV when I pulled out the VCR and struck the outer case somewhere on the back of the TV before falling to the floor. The cable box could have been on or even if it wasn't there is still power to the circuit so you can power it on from the remote so which means there would still be power to the transformer. Could the cable box when it fell passing over the purity magnets separted only a small distance by the casing, somehow chaged their magnetic properties where now they need to be adjusted?

Thanks again for the help. As you can tell, I'm seaching for the root cause which I'm hopeful will lead to the correct diagnosis the first time. Plus, I would really like to know so I can prevent it from ever happening again.

.....like I mentioned at this point, I am not sure if you have a degauser problem or not? Without seeing it & knowing exactly what you have and what happened, it is only assumption.

Rather than investing in tools that may or may not solve the problem, suggest getting a TV tech or ask someone who has some experience.

To answer your questions... yes, magnetizing the tube can affect the entire screen.

It is very unlikely that the cable box's txformer can magnetize the tube. The idea was that if the box physically hit & moved the magnet rings on the back of the tube, the colors would go off.
