Hi folks,
I see many having issues with the U3011 monitor display (Westinghouse guts?)
I have one that would work if I unplug power from wall every once in a while. Was like that for about 3 months - Now, it doesn't turn on at all (front LEDs), but no backlight or other signs of life.
I replaced the Power Supply PS-2201-3-HF board and that took care of the problem.
I'm trying to repair the PS-2201-3-HF board. It has 2 connectors sets (top and bottom)
Bottom set seems to be just 24V and GND with ENA, ADJ, and HDCR
Top Connector, P802, is identical, but P803 has 5, GND, 24_EN
I buttoned up the Monitor so I'm troubleshooting this board on my workbench. To turn all the supplies on, I'm assuming I tie 24_EN to 5V (with a small resistor)?
Do I have to do anything with the ENA and HDCR pins??
Any common failures that anyone can share on this board?
Thanks
