Question about SAMTRON 55V 15" CRT Monitor
The monitor`s display adjustment panel is showin "CONTROL LOCKED"
I cannot change any settings(like brightness,v-size,etc)...

Have you tried holding the "MENU" button on the front panel of the unit?
For my 150MP, it must be held in for 5 seconds. (the menu actually goes away. Then you press MENU again and it comes back unlocked.)

Hold the menu button down for 15 seconds. This worked for the Dell E173 monitor I was testing. This has worked for other models of monitors as well. I found this on the Dell support site: https://support.dell.com/support/edocs/monitors/E173FP/En/controls.htm

This issue would be resolved after disconencting the zenar diode from monitor key pad and the diode on main board which is beside LED.
