What would you say is the problem .

25 inch monitor loses color intermit. (red i think, if it even matters)

sometimes its all good, sometimes red color is about for several minutes.

if red gun is out, how hard is that to fix, I can fix games, and cap monitors, but not sure on the gun thing.


looking at pick up a game with this problem.

thanks
chris
 
Have you gone over the the solder joints on the neckboard?
The color drive transistors and resistors get real hot and cause problems with the traces and solder joints.
 
look for cold soldered transistors on the neck board
 
On tv's its very comon is for one of the drive transistors on the tube neck board to go intermittant if its not dry solder joints, change the red output transistor with say the blue, then run the monitor, if the blue then disapears its the transistor! if the red still goes then change the drive transistor with the blue one! that way you can narrow down the transistor without spending money replacing ones that are ok and without using expensive equipment like an oscilloscope! but do them one at a time or your get in a mucking fuddle!

cheers
