Sanwa 29E31S Help! Red and Blue but No Green Showing
I just picked up a 29E31S and it has no green showing (see pic below) I heard this problem couldn't be solved with a cap kit and was most likely a Pot, Transistor, bad solder or worst case scenario and bad tube. Anyway I tried a trick I heard about taking a grounded wire and touching each color on the back of the neck board to see if the color flashes on the screen. I tried each color and Red and Blue flashed on the Screen but green did nothing at all. I notice when I touch each color it gave a zap sound but the Green did not. Is this tube bad or could I somehow check another way? Also my other Sanwa is doing the same thing although it still has some green left (50%) and when I touch the neck board with the grounded wire, the green flashes on the screen. This most be common thing for 29E31S since I have two with almost the same problem. Any help would be nice, and btw I check the VGA cable and they work so problem is coming from the Tube or the Chassis.
Thanks,
Kane
