No High Voltage after Adjusting Horiz Width Coil

Okay, so I recently threaded about capping my WG4900 in an attempt to rectify a blank 2" of monitor that the screen was not filling...

I tried moving the Horiz Raster pin connector, but no dice.

Tried capping it, with no dice.

So I tried turning the horizontal width coil, which I did with the power off. I turned it slightly clockwise, then slightly counter-clockwise, then slightly clockwise again.

I reconnected the power to the monitor and turned the cabinet on and BOOM! no high voltage. The chassis is getting 120v and the fuse is good. Anybody else have suggestions on where to go next?

Many thanks!
 
i'll check... but it was working right before i shut off the machine to adjust coil... soooo frustrating... :mad:
 
boom

If you got a boom then i would guess that you put a cap in backwards or under voltage cap in.
maybe your flyback took a dive.
 
its mounted horizontally, so adjusting the vertical size, actually adjusted the vertical size.

coulda been the flyback, I was getting a few "ticks" from where I think was the anode cap... thought it was the humidity (houston, raining, game in garage next to door) but maybe it just went.

don't think it was cap polarity because the game played fine for several minutes while I was trying to adjust its width.

What I don't get is... how would the Hor Width Coil stop HV? It has to be something like the flyback, right? I know, I'll just hold the anode cap in my hand and see if i get a sting! =/

Just checking. I worked on a 4900 a while ago that looked "widescreen" eg a great looking picture, but you couldn't fill the screen top and bottom (when mounted horizontally). Turned out to be a bad cap - but not an electrolytic. Width would definitely be different.
