Finally got around to this monitor. It turned out to be a bad TR 306 (Thanks Ken for the direction). I also had to put a jumper across R351 on the bottom. My Pitfighter had a jumper where the Red Alert had another resistor on the solder side so I put a jumper there, too. Now the game looks awesome (for a Red Alert) but I have a problem with the board I got from Bob. It will not stop rolling when in the monitor. I have 3 XY boards now and two work, but the other one does not. I contacted him and he said it tested good on his jig. The monitor is mounted longwise up and down and the roll is side to side. I have tried to adjust the pot, v-hold and both sizes with no change. Solder joints have been reflowed and all caps replaced except C359 and C311. Could these two caps cause a good test on the jig and give problems in the monitor? Or is there someting I should be looking for?
Thanks
