I've put together a home made arcade cabinet with PC and emulators, so I'm using an old CRT Panasonic TV I picked up off Gumtree.
It's got a purple patch in the bottom left, and I've even bought a degaussing wand – the standard "walk backwards making circular motions" doesn't fix it. Someone recommended a "flicking" technique where you flick the button very quickly to produce random interesting results, and I got something not perfect, but better, but after a few days it reset itself back to having the purple patch at the bottom.
It's internal degaussing doesn't fix it either.
Yes I should try and replace, but they're getting scarce when I've checked the last few times, and it's hard to find one with this set of features (S-Video, and Component input, and not too big but not too small) I like this one, so I'd like to explore repairing... as you can imagine, repair stores don't really do this sort of thing anymore.
Info from back of TV:
Panasonic Colour TV
Model: TX-68PS12A
Chassis: MX10A
240V ~ 50Hz 165W
Fully aware there's enough voltage to kill you, around the front of the screen, I've read a lot about this – though I'm very much a noob. But I'm getting desperate.
Here's a photo of the purple patch in the bottom left:
It's purple while the screen is blue but it's even more pronounced when you have a red scene and the patch is yellow instead. Here it is on Donkey Kong when the girders should be red but they're yellow:
What kind of problem could we be talking about here, and what would be involved in fixing it?
