You are going to have to look for open PICO fuses along with bad bias resistors close to the ic's. You should have close to +27 and -27 volts of B+ on the chips to start with. That will ensure the fuses are good. Then trouble shoot the convergence circuit from there.
If the ghosting is like a 3D effect its your convergence ICs , but if its like a blue Halo around objects that usually means your CRT coolant has congealed and will need replacement. The blue is the first tube to congeal for some reason, followed by green. Red seems to be not quite as prone to this. It is a normal occurrence n sets about 4 years old to need the coolant changed.

Adjust the convergence manually. It's a pain and takes alot of patience. The diagram for the remote buttons helps a lot. If it won't adjust you'll have to replace a part inside the tv.
Good luck! Hopefully it'll adjust.
This problem is beyond a blown fuse most likely. The fuses for the unit are located on the circuit boards and the back will need to be removed to access them. This problem could be due to a missing voltage that is used to turn on the picture section of the electronics. I would search for a used unit on ebay or parts on ebay and swap out the boards. The board swap is not too complex but voltages are dangerous within the set and service by a qualified electronics technician is recommended on this unit. Thanks and good luck. Dan
on the main board of the tv there is a fuse located if that is faulty this can happen,there are also many other possibilities but check out the fuse first many a times replacing the fuse solves the problem
as its very negligible to replace the fuse the cost of fuse is under $1.
You are not likely to find the board easily, but you should be able to replace the convergence ICs relatively easily. Look at the board. Try resoldering the pins on the STK ICs. If that fails to resolve your problem, replace the ICs. There may be some pico fuses located close by or low valued resistors that may be open. Check for those as well.
