The lower right corner of my TV has a pinkish tint to it. When the screen is green, this area is purple. When red, this area is blueish. I have checked for any kind of magnetic issues, and even moved the TV, but the issue still exists. What could it be?

Re: Color issues in the lower right corner
Unplug the set overnight and plug back in and turn the set on . If the spot goes away alittle then do this again. Up to three days > if that dosent fix the problem then you have a problem in the deguissing coil curcuit. Probably a cod joint on the thermister or a bad relay , a bad coil . Not a big deal repair. Good luck

Purple Panasonic PC>TV Problem:
The VGA cable uses three primary color RGB channels.
Red, Green, and Blue.
The picture is made up of pixels or dots arranged in a grid along the "X" horizontal axis and "Y" vertical axis.
The computer mixes the intensity of each color channel to create a unique color per pixel.
All RGB at 100% creates white.
R+G creates yellow.
R+B creates magenta, ie purplish.
G+B creates cyan.
So a purplish tint sounds as if your Green wire has no signal, which may indicate a faulty VGA cable or VGA socket.
Put another way, (R+G+B)-G=R+B=magenta.
So try another VGA cable, spray all socket pins with "Servisol " or similar contact cleaner.
All 0%=Black; All 50%=Grey; All 100%=White.

sounds like the linear adjustment is out of whack.....most projection type tvs, projection, lcd, plasma, have to be correctly aligned so that the color grids overlap each other to properly display the correct hue being created. you'd need the service code to re-adjust it, or have it serviced. also possible that one of the color grids is bad, but if you have all three (red,blue,green) colors showing on the entire screen area i would doubt it
Check any magnatic device near TV which causes purple color on screen. That device can be Speaker, Electronic toy, Watch like that carring piece of magnet inside. Remove that device and turn OFF your TV for half a hour, then power again. Hope the color will be fine n normal on entire screen.
Is it a green tint at some areas alone, oris the entire image having a green tint?
If it is a color patch at the corner or other areas of the screen, in all likelihood it is a degaussing problem. Color patches happen when the TV is moved from one location to another, or if some magnetic source is placed close to a CTV. Did you put a radio or Tape recorder or Walkie talkie toy or any magnetic source near the TV? if yes, remove it. And the automatic Dregaussing circuits in the TV will resolve the problem in a couple of days.
But if there is an overall Green tint on the picture, it signifies a problem in the Video output stages, and there is nothing you can do, but call the technician (unless you know solid state servicing?)
You have a bad connection on the CRT board thats mounted on the end of the picture tube it sounds like, or the socket on that board that plugs into the TV set is intermittant or has a bad solder connection on it. Good Luck
