You can try adjusting the Red color output. (Very touchy adjustment)
you take off the front cover/speaker cover, there should be a access panel. Behind
that, there should be a small square black box with 6 screws on it.
This is the focus block. (At least this is where most of them are
It sounds more like you may need less red in the mix. There is a screw for each color. R, G, and B. Do not
mess with the focus screws, just the ones labeled 'SCREEN.'
Go to an unused input where the screen should be dark. Barely turn the red down in a dark room so that the red spot is at the same level as the Blue and Green.
Use an insulated screwdriver and DO NOT TOUCH the focus block and ESPECIALLY NOT the back of it. Very HIGH VOLTAGE. I found that out the hard way.
Do not turn any of these up too high or damage may occur and the TV may detect a short and shut off.
have found that if the three colors are adjusted in a dark room to
where the 3 color spots (R/G/B) are just barely visible on the screen
at equal levels, there is a pretty good color balance.
The convergence ICs and the six 1.8 ohm 1watt resistors need to be replaced. You can get the convergence repair kit for your model at www.tvrepairworld.com which has the Two Convergence ICs and the six resistors plus the CD with instructions on how to do the repair.
It sounds like the CRT tubes are weak which will not practical to replace them.
But try to clean the dust on tube first and if it doesn;t help do this...
Risk of electric shock, focus block carries 4 kilo votls, do at your own risk or DO NOT do it at all.
Just try to adjust the screen voltage adjustment to brighten the 3 tubes from focus block, to do this you have to open the back then let the TV run for abut 10 minutes beofre adjusting, each tube has its own screen voltage adjustment, read the label make sure not to tuch the focus adjusment, do not crank up too much make it very slow or your TV will show retrace lines or it will shutdown.
