Logiq 200 Ultrasound Screen Brightness Issue

January 31, 2018 09:27

I'm currently trying to fix a LOGIQ 200 Ultrasound in a provincial hospital in Cambodia. The CRT monitor displays at a very high brightness making it unusable and the brightness dial has no effect on the screen brightness.
Any help on this problem would be greatly appreciated.

Hi Laurence, your problem is a resistor that is broken, I mean open. If you write to me I will email the service manual.

Your problem is common in CRT monitors, so check the resistors where the grid or Bias... The problem will be in a voltage divider circuit. Anything you may contact to me at: ramon.portillo.m@gmail.com
