Question about Philips 190B6CB/27 19" LCD
Philips say "To unlock the OSD Controls press the “MENU(OK)” button for more than 10 seconds while there is video input from PC"
Posted on Apr 03, 2009
This type of monitor has problems with the switches. The switches behind the push buttons malfunction after two or three year of use.
If the "OSD main control lock" and unlock appear, you have to change the ok push button switch. The switch it self is only 25 cents. However if you never used a soldering gun you should ask an experienced repairman to fix it.
All other problems are related to malfunctioning swithes with the other controls such as volume or brithness. I fixed the problem in 15 minutes and 25 cents

I simply unplugged the whole circuit board where the switches are on. The speakers don't work anymore and the monitors on/off-switch became useless. Of course no monitors menu will ever open again.
But the nervous flickering error message is gone. For free. I never used a soldering gun ;-)
