Sounds like the convergence supplies are down or the conv eeprom has reset. This manual is not in PDF form. I have the paper manual if you need it, but for this you should not. VZ4 chassis. This is from Mits: 1. CHECK FOR -8 VDC TO THE CONVERGENCE PCB AT "VM" CONNECTOR PIN 3, IF LOW, MISSING OR NOISEY, CHECK C936 (1000 UFD 16 V) AND C935 (100 UFD 16 V) ON THE MAIN PCB. 2. CHECK C924 (1000 UFD 36V) AND C925 (100 UFD 50 V) IN THE -24 VOLT SUPPLY CIRCUIT ON THE MAIN PCB. 3. GO TO THE CONVERGENCE MENU (MENU 2 3 5 9) AND CHECK THE ADJUSTMENT SETTINGS FOR CONVERGENCE. IF ALL ITEMS ARE SET AT "127". THE EEPROM SETTINGS ARE AT DEFAULT. CLEAR THE CONVERGENCE MENU AND ACCESS THE OPTION MENU (MENU 1 3 7 0) USE THE ADJUST BUTTON TO SELECT E2RESET AND PRESS QV. THIS SHOULD INSURE THE EEPROM IS CLEAR. AT THIS TIME ALL ADJUSTMENTS, CONVERGENCE GEOMETRY AND CONVERGENCE SHOULD BE DONE. 4. CHECK FOR 20 VPP VERTICAL PULSE TO PIN 9 OF THE "VJ" CONNECTOR TO THE CONVERGENCE PCB, IF MISSING, WEAK OR DISTORTED, CHECK PULSE AT SOURCE PIN 7 OF IC401 (PUMP UP OUTPUT) ON THE MAIN PCB, IF THE PULSE IS NOT CORRECT AT PIN 7 CHECK C402 100 UFD 50V AND IC401 PART # 270P064020. 5. Z905 IS OPEN. CHECK FOR LEAKY D913 PART # 264P722010, OFF OF PIN 12 OF T900 (15-VOLT LINE) ON THE MAIN PCB.
