Mitsubishi | CT25AV1BDS | Service mode & EEPROM settings | Switch on with mains switch and press service microswitch, select button 9 on the remote within 5secs. You will now be in the service mode. Use the buttons on the remote control for the following adjustments:
* to toggle between adjustment displays
1 cancel; 2 increase adjustment code; 4 decrease data value; 6 increase data value; 8 decrease adjustment code; 9 adjustment mode on; 0 write to the eeprom( press this to write your changes to the eeprom)
Here are the options-
TUN 0; SAT 1; AUD 10; ATS 1; STD 1; SYS 1; AV1 2; EEX -; SPK 1; EEP -; ABG 02; A1 02;AL 00; ADK 15; MNP 70; TXT -; FFT 1; VOL 74;HYP 1; SCP 20; FMP 23.
not all options appear to be available to some models. Adjustments in the VCJ mode will be in default mode and it will be necessary to observe display in order to set-up width height ew etc. | 14-09-04 |
