Title: Wells U5000 green channel problem
Post by: Bradh on July 01, 2014, 12:21:14 am

Hey Everyone!
I'm having an intermittent issue with my green channel on my Wells U5000 monitor with my mame setup.  Running Ultimarc's newest video card with jpac and ipac. 
I'm not sure where to start so I thought I would see with the professionals say on this issue.
Sometimes my green won't show up.  I can shut off the monitor and restart the system and the green channel will not come through.  If I turn the contrast on the remote board then I can get the green to come back.  Sometimes it will show for awhile and then cut back out.  What are your thoughts on what the issue may be?
Thanks in advance!

Brad

Thanks Grantspain!
It ended up being the transistor. No problems since I changed it out. Thanks again!
