Red and Green Convergance Issues. Started about 3 weeks ago but would subside after set warmed up. Now the double images remain constant. Can this be fixed, if so, is it costly, or should a new set be considered??

Re: Hitachi 42" TV
This is a problem with the convergence circuit. If you can solder, try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. These ICs are large and black, attached to a heat sink and are marked STKxxx.

You have a convergence problem, you will need to change the convergence IC's STK392-110, there is also 12 6.8 1w resistors that need to be changed, there is also 2 fusilbe resistors that may be open. You can probably Google the IC's as a kit and find them all in one kit.
You can fix this yourself and save about $300-$400 in repair bills.
your problem is called retrace lines
it is due to
1 supply to red out put is absent
2 problem in red video output
3 loose contact in red output ckt
4 connector loose
5 crt base loose
6 circuit from red output of chroma ic to red video input
7 chroma ic defective
