Chassis : C-2105
FCC ID : PJIC21F05120

The display went black during a switchover from D-SUB to BNC input; no response was to the key inputs anymore.
After switching off & on again, the display came with overdriven picture and very high brightness.

Symptoms:
*Brightness too high
*Excessive red & green color overdrive
*User brightness settings can be stored, but the smallest setting is way too bright
* Factory brightness can't be stored, always 255 after switching on or swapping resolution, however setting the factory brightness fixes the problem temporary

Is the EEPROM defect? Does anyone have a good EEPROM dump for this model?
Please send it to

Thanks,

I have swapped the EEPROM: a few cells were stuck at FF, that's why the brightness was inadjustable.
