I drove from chicago to atlanta today and gave a buddy a house warming gift of a blitz 99. Well we were playing our second game and sure enough like a light switch the focus went way out. So i played with the focus pot on the flyback and it went all the way to the right and that is when it looks the best. I dont know what else to adjust. It was seriously like a light switch though. Played with brightness and contrast and it didnt help. Please any info would be great. It is a wells 25k7197. thank you so much
 
Did you check to make sure the neckboard was on tight? if you drove it all that way, loaded and unloaded, etc, it might have wiggled a little loose, causing a loose connection on the focus pin...

tube

I would check the wires coming off the flyback to the neck board and see if the one going into the neck board socket came out or is not push in all the way.
See if neck board needs to be push on further. Do not turn a neck board, they are pushed on and pulled off!
Possibly some particle in the tube is messing with the focus grid. a long drive may have dislodge a metal fragment and is shorting your focus in the tube. I have seen that a couple times but more then likely it is your neck socket wire.
If you find it is in the tube, you could lightly tap the neck tube in front of the neck board were the glass starts. Have someone watch the screen and see if that changes as you lightly tap. It may come loose or maybe it will burn itself off after awhile too. Use a screwdriver handle to tap lightly(tap as lightly you would do if you had to do your nuts! Unless you are a sick S.O.B. then tap alot less!

ah, tried the above, except tapping so far, but messed with the neck board, wires, etc. This is something i havent experienced before. I have been dealing with games for like 10 years, and this totally eludes me. thanks for the help so far, please keep the info flowing. i would love to get this thing decent
 
take the cover off the flyback, turn off all the lights and see if any sparks are comming from the fly... if nothing.. keep everything on for 15-20mins.. turn the game off... then very lightly touch diffrent parts on the chassis on the monitor (looking for sopts that are very hot)

if you feel something very hot then chances are that component is causing the trouble.

but yah also check to make shure everything is pluged in tight, long rides can sometime's losen up connections... also make shure that all your plugs where the wires goes into the plug/clip that they are pushed in all the way.

i hope this can help you, pictures would be nice to see, of the probem on the monitor and of the chassis,

also another thing you can try is switching out the game pcb for a diffrent one to see if u get the same problem, if you do have the same problem you know its not the pcb and its somthing on the monitor thats causing your problem

also another thing to check is on the neck on the monitor thair is the color switchers (i know thats not the correct term) this is on the neck not the pcb board connected the to end of the neck, look to see if they have some type of glue on them so they do not turn, if these do not have some type of glue then maby while on its jurney they mite of turned some and thats what causing your problem

As stated above, if its not a loose connection its probably a flyback going south. Have you rebuilt the chassis at all? I would replace the flyback.
 
how funny, I have a Blitz 99 that had the same problem (until I did a body swap with a raggedy Blitz 2000-turned-Sportstation), a K7500. I was under the impression that it was the focus knob on the flyback that was the culprit, but I watched with my own eyes in the hard drive test against a black background that the black turned into a bright grey all on its own. it was actually the Screen adjustment that started to walk on it.

turning that back down, the focus looked fine. I had to experiment with it until I found a position for the Screen that wouldn't cause this problem anymore and it's been fine, my games operate in a commercial environment, and it looks substantially better than the U5000 I had running with it before.

I've never read anything about this, but do the adjustment knobs in flybacks go bad? are they replaceable components? (I'm just now learning that black box is just a case that's removable? wtf?) cause it's one of those things where I'm putting off replacing the flyback until I really need to do it. :)
 
Bob R, for $26, sells flyback+cap kit+fuse+HOT. If it's for a friend and you want to bulletproof it, that's cheap insurance.

My bad.. that's for the 7000, but he has other K7XXX flybacks, so you should be able to get the parts from him.
