Cause: Corrupted value in EEPROM memory, IC346, register 67
Cure: TO AVOID CHANGING ALL MEMORY LOCATIONS:
1. With set unplugged from AC, ground pin 6 of memory IC (IC346).
2. Power set and turn on. Video and/or raster should be restored
3. Enter Sevice Mode using remote control (06-25-96 menu).
4. With cursor up/down select register 67
5. With right/left cursor, set value to 1D
6. While on remove ground from pin 6 of IC346
7. Press MENU to save. Press 9, then right cursor, set will turn
off
8. Break AC power for 10 seconds to insure value is saved.

If full video is restored in step 2 but readjustment of register 67 does not
resolve problem, do the following before replacing the EEPROM:
A. Perform steps #1, #2, and #3 above.

(Using remote, press # 1 for page A, # 2-page B, # 3-page C, #
4-page D,
# 5-page E, # 6-page F, # 7 page G and # 8-page H.)
C. Return to page A (press # 1) and press A/CH on remote to write
to write
defaults from the micro processor to the memory IC.
