I have 3 Iiyama ProLite B2403WS LCD monitors.

Out of curiosity, I took one apart, and wondered what the pictured pots are for? I can't find the service manuals for them to find out.



Thoughts appreciated. Thanks.

Broadly speaking - don't mess with them unless you know what you're doing.

The one on the PSU board seems to be something to do with the CCFL inverters. The one on the LCD interface - don't play with it, you'll go blind!

 

The Blue presets will be voltage adjustments , the others look like brightness control of the lcd.

If it's not broke, don't fix it!!

 

Now that you mention it, the lcds are all dim looking. Not backlight broken dark but at with Brightness and Contrast set at 100% it looks like its only 40% brightness.

Edit: Well I tried both pots and they didn't affect the brightness at all. Bit disappointing.
