Hi BOO
Yes with MODERNISH monitors the COLOUR BALANCE is controlled by a COMPUTER CHIP ( MICROPROCESSOR). Like all COMPUTER CHIPS this can get really MUCKED UP
,
Since you are unable to effect a COLOUR BALANCE ADJUSTMENT from the front controls, it would suggest you have a problem with this computer chip.
The possibilities are either that it is FAULTY or maybe that its just plain MIXED UP >
If the FIRST CASE then it would DEFINITELY need to be repaired by a SPECIALIST . If its the LATTER the chip can sometimes be RESET ( like a REBOOT) .
Again this is probably best left to a specialist. Although I will check around if theres any info available on a straightforward method of RESETTING the CHIP.
Sorry I can't be of MORE HELP at the MO .
Best of LUCK .
