That and the number of buyers trying hard to hard-mod their monitors seems to have raised awareness at Yuraku how they have unnecessarily degraded products with excellent panels by stripping them off the backlight control (and hence meaningful brightness settings by the user).
If they can't fix it by enabling backlight control through the OSD via a firmware upgrade, a simple control for the ADJ pin according to the French design would do for me, and Yuraku should have no problem with manufacturing these at cents apiece, and retrofitting the monitors with them e.g. on returns to the service centre (or even leaving the latter to the more courageous customers).
Yes, I agree. We all know that these monitors are very cheap but saving costs by disabling backlight control is weird. To consumer standards, no backlight control is simply manufacturing/design error. I'm surprised there are many people (UK from OCuk forums) that can live with the insane brightness! 
It could be "repaired" by service center (French bypass cable mod is easiest) BUT only possible if monitor has the correct moddable PSU.
My PSU board for example would require either replacing PSU board or soldering. It is also very suspicious why factory would actually made PSU board that is impossible to adjust ADJ signal because they "sabotaged" it.

BTW, from the fact that the manual documents a top central opening in the monitor case as one for a light sensor (that some Iolair models sold in France apparently came with from the factory), we know that a similar method of adjusting brightness is indeed already part of this monitor's design.
I did not know some Iolair had light sensor! Where did you get this info? Was this monitor more expensive?
The manual and Yukaru did confirm light sensor is optional. Manual says if light sensor is equipped, you can adjust 2nd brightness (=backlight) via OSD manual/auto! This would require extra circuitry to interface with OSD controls but still shouldn't be that expensive.
Yukaru have told me that the monitor bezel design is public source. I doubt Yukaru is the original design. So far, it is the only one with working HDCP but in the manual, light sensor & DVI & audio = optional 
Waiting for Yukaru to confirm they are original design or not.
Anyway I strongly believe there is no original or clones. All these brands just order screens with specs from same OEM manufacturer. It is only rebadged.
Some brands will choose this or that to be optional. So Yukaru has HDCP, others not. And some Iolair have light sensor, all others not 
If these monitors can be fixed with working backlight control or moddable panels easily sorted-> BIGGER SALES!
If not, too bad for us since cheapest "regular" 24" VA-panels are 500+ euros... 
ONLY WAY IS FOR MANY PEOPLE TO MAKE THIS INFO PUBLIC AND COMPLAIN SO THEY DO SOMETHING ABOUT IT
