Question about Televison & Video
Where would they be on the signal board. The Signal board is the one where everything plugs into right? Also were would I get the right coupler replacements?
I also was thinking about replacing the STK392-110 IC'S and the 6.8 ohm 1 watt flameproof resistors on the Convergence board because of the halo efect issue. Do you think this is a good idea or will fix the green halo effect?
The halo effect is due to the green and blue CRT coolant being congealed this is a common problem. Red will not have the same condition. As for the opto-couplers they are located on the large signal board in the middle of the board all lined up in a row they will have board location numbers of 7412, 7406 and 7413 . 7412 is usually the culprit the part numbers for 7412 is 9322-105-14682 7406 and 7413 are the same part number 9338-894-15682
