Question about SAMTRON 78DF 17" CRT Monitor
My SAMTRON 78DF monitor is having a problem. The Monitor's menu appears by itself. It was discussed in a previous description but not resolved. It shows the control lock window and will fluctuate between locked and unlocked without activation of the menu button on the monitor itself. The control lock window is switching between the CONTROL LOCK and UNLOCKED mode every each 5 seconds and is smack in the middle of the screen. When unlocked I can press the exit button and it will change to the blue - access function window but the up down buttons do not work. It will then go back to the red locked window and continue through the rotation. Please advise...
I have a PDF of the service manual, and I'll be glad to email to you upon request. It may help. firstname.lastname@example.org
