RGB- Blue will not change value on screen?
« on: April 22, 2013, 09:21:29 pm »
When I adjust the Red and Green there is significant changes to the monitor, the Blue however, nothing?

Is this a capacitor issue or?

(Never worked on a monitor before and don't want to electrocute myself!)

Not that I can tell. On the test screen the blue appears to be black and I cannot get anything close to purple to show up.
