My Pacman's monitor was starting to show signs I needed to rebuild... and I remembered that I had bought a "working/rebuilt" K4600 a couple years back still sitting in a box. I pulled the old and dropped in the new expecting it to work... and...
Well... here I am.
The new chassis is exhibiting an odd behavior. It will increase in brightness until a certain point... then cut brightness to a very dim level, then increase in brightness to a certain point... then cut brightness...etc...etc...etc...
Using the screen pot on the neckboard does nothing immediate/noticeable, but it does seem to effect the level of which the monitor cuts brightness to and the level it takes it to on the high end before cutting out.
I figured perhaps the blacklevel pot was going bad on the one daughter card... so I tried the daughter card from the chassis I pulled... unfortunately it exhibits the very same behavior.
I have not tried exchanging the horizontal/vertical daughter card as of yet.
I've also noticed at the very high end when the screen is very high it affects the focus as well...
Aside from this issue, the monitor looks beautiful.
Any suggestions on where to look?
Thanks!
