The fault is with its video output stage circuit. The fault is called "one color predominant' screen. In most cases, this might be to a loose solder terminals at the video output stage circuit board. This board can be located at the neck of the picture tube, will plugged on to it directly.

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.
It might be due to picture tube problem... As its too old, the picture tube might be weak and hence you might get colors at the edges.. Better replace the picture tube with a new one to solve this problem
If your picures are all purple it means that the green colour is missing. TV colour is made up by mixing Red, Green & Blue. Removing Green leaving Red & Blue makes purple. Study the green colour circuit for a fault and confirm that the green gun inside the tube is working.
your camera CCD is gone just replace it near your servive centre https://www.google.co.in/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwjw5aHq67_UAhUKuo8KHSMoDFEQjRwIBw&url=http%3A%2F%2Fwww.ebay.com%2Fitm%2FSAMSUNG-PL100-CCD-SENSOR-FOR-REPLACEMENT-REPAIR-PART-%2F261071736686&psig=AFQjCNGNxusI0WektQaSxFc7lgATrkPq2w&ust=1497615818313040
