Mando,
The ICs are STK391-020
Additionally these are some notes from the mits site:
CONVERGENCE AND RASTER DISTORTION
1. 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. 2. CHECK FOR 20 VPP VERTICAL PULSE
TO PIN 9 OF THE "GL" CONNECTOR TO THE CONVERGENCE PCB, IF MISSING, WEAK OR
DISTORTED, CHECK PULSE AT SOURCE PIN 7 OF IC401 (PUMP UP OUTPUT) ON THE
SIGNAL PCB, IF THE PULSE IS NOT CORRECT AT PIN 7 CHECK C402 100 UFD 50V AND
IC401 PART # 270P064020. 3. CHECK FOR -5 VDC TO THE CONVERGENCE PCB AT "GM"
CONNECTOR PIN 10, IF LOW, MISSING OR NOISY, CHECK C936 (1000 UFD 16 V) AND
C935 (100 UFD 16 V) IN THE -8 VOLT SUPPLY CIRCUIT ON THE MAIN PCB. 4. CHECK
C924 (1000 UFD 36V 105 C) AND C925 (100 UFD 50 V) IN THE -24 VOLT SUPPLY
CIRCUIT ON THE MAIN PCB.
BEND ON LEFT SIDE OF PIX
1. IF THERE IS A BEND ON THE LEFT SIDE OF THE SCREEN DURING CONVERGENCE

.01M-Z) C8X01 IS LOCATED OFF OF "DK"CONNECTOR,PIN 4.
