I will start with a simple deduction that one primary colour has gone, the set has three Red, Green and Blue with this and our easily tricked eyesight we make other colours.
To me if this was a hulking glass tube type TV I would think one of its tube guns has stopped working this can be the chroma drive IC or more likely an out put which is mostly transistors mounted on the tube base gone bad or dry joints in this area. A tube can go but they mostly age and go off colour over time, I have also seen sets have power supply troubles which causes a low supply rail this results in some very strange events. A hoover started up in front of the screen can magnetise it as can a child with a strong magnet moving it around on the glass, a set will try to cure these last two each time its switched on (degauss) though the magnet one will be harder to cure! I am afraid it would need a service call to determine if its a joint or small part it may then be worth it, while a tube problem forget it. Also if this is a flatscreen then its possibly not worth it anyway, if its the screen+output IC set up, a screen is about 66-75% of a flatscreens build cost. On the other hand if its the main circuit board all an engineer can do is replace it with a new one (if around) because they are made in such a way with machines a man with a soldering iron stands No Chance. Hope this helps.....
Use the three coloured wires coming from the wii and connect them to the three on the back of the tv, make sure the colours match. Then plug everything else in and turn on, then go to your tv settings and choose the right input.
hi, if you know little fixing tip's? here's my tip's sound's
like converging ic's,gone bad. on the left board there's two a touched to a big heat sink.but before you start'.there's three wire connected to the board written. red .blue.and green.check for burn film resistor's on line red. replaced it with the same.good luck.
Either your picture tube has gone bad or the transistor or IC on the crt board, on the picture tube, that feeds the blue gun has gone bad. You would have to test the transistor to see if its shorted or open with a multi-meter, or check the voltages to and out of it. The voltages are around 200v and dangerous if touched, best left to a proffessional. If its the transistor/IC it would be a cheap and easy fix by a repair shop, if its the tube, you may want to go tv shopping.
Your Picture has acquired damage that has caused the colours to leak and not blend together. Call the TV Technician immediately if you don't want to make it worse. I suggest you don't put on the TV for very long time till its fixed. Not more than one hour each time
Your degaussing circuit is not fully 'demagnetizing' the picture tube.
You can manually degauss it using a strong magnet, but it's tricky.
With a tool made for demagnetizing you simply hold it close to the
center of the picture tube and using a circular motion slowly spiral
outward to the outer edge of the tube, pulling the magent further away
from the tube at the same time. The same can be done using a strong
magnet although the results may not be perfect. You can experiment with
a magnet using wiping motions as you bring the magnet closer to and
further away from the tube.
