Just wondering.... I was working on an electrohome monitor where I
couldn't adjust the flyback down all the way to bring it to the correct
darkness. I could also not lower the screen control on the flyback
enough to get the screen to be totally black. I tinkered with it for a
while and after unplugging and plugging in the yoke connector on the
chassis several times, it just started working normal. Worked fine ever
since.

My guess is you had some trash on the guns and it got dislodged or burnt
away. Shorts can produce too much brightness. See Randy Fromm, 'Low voltage
(short) means high brightness' IIRC.

If the monitor has not had a capkit installed recently then it's
possible that capacitors C905 (10 uf @ 250 volt located next to the
large filter cap on the main board) and/or capacitor C107 (10 uf @ 250
volts located on the neckboard) are bad. Typically they will be found
physically leaking and/or have one lead broken off. When either one or
both go bad you'll have brightness problems.

Another thing that can happenn is that if yours has the original
flyback transformer (a known high failure item) the screen voltage
winding inside it is probably going bad. Replace the flyback with a
brand new one.

Shhhhhhhhhhhhhhhhhhhhhh!!!!

Quietly put the monitor back in the game, screw on the back door, and never
speak of this again. ;)

I had a G07 lose vertical hold for no reason. I opened up the back of
the game to take a look at it, and just before I touched the pots for
it, the hold locked back in and never lost it again.

I guess I had a magic finger or something. Never even made contact.

I've got a few in my furnace room on the floor, been there for 6 mos., but,
alas, they still havent fixed themselves, guess they need more time.
