Hi Terry: I will assume (you know what that means) that you are talking about the atc311 chassis. I think this is normal operation. It looks like the LED is lite when the thing is cut off. This is the set procedure: Screen Control Adjustments: 1. Apply a 0 IRE Flat Field pattern (TP2) to the Component Video Input (Y, PR, PB). 2. Make certain the preheat and preset conditions have been met. 3. Enter the serviceman menu using the front panel buttons by pressing simultaneously "MENU" and "CHANNEL DOWN" . Use "VOL UP" to place the "V:" value to "76". When a parameter is specified use "CH UP" or "CH DN" to change to the correct parameter number, then use "VOL UP" or "VOL DN" to change the value of the paramter. 4. Set all three screen controls on the focus/screen assembly to minimum (full CCW). If any or all colors of the On Screen Display are badly out of focus, the individual screen control for those colors will need to be turned back up until they regain focus. 5. Set Red Cutoff (P:12) to V:32. 6. Set Green Cutoff (P:13) to V:32. 7. Set Blue Cutoff (P:14) to V:32. 8. Set Brightness Offset (P:15) to V:127. 9. Set Red Drive (P16) to V:64. 10. Set Uni-Color (Green Reference - P:17) to V:64. 11. Set Blue Drive (P18) to V:64. 12. Set AKB (P:19) to V:2. 13. Making certain the 0 IRE Flat Field pattern (TP2) is still displayed, observe the LED's located on the kine boards on the neck of the CRT's. Adjust the red, blue and green screen controls to light all three led's. The goal is to have all three led's full on. DO NOT ADJUST THE SCREEN CONTROLS AGAIN AFTER THIS STEP!!!
