brought this k7000 back from the dead to verical collaspe to this, the adustments help alittle but not too much. not sure where to go from here, any suggestions? did a full cap kit on it an touched up alot of solder joints. sync is good since i just had another k7000 hooked up and looked fine.

Looks like you need to adjust the sync, and the 50/60 Hz pot.

i adjusted the 50/60 pot all the way from one end to the other and it changes the pic but doesnt inprove it and the same with the horizonal hold.

Could be the V hold causing what looks like a sync issue. Try adjusting the V hold.

Tried the v hold also with same results. Just changed the picture. Going to. Test all the pots to see if they are good. Two were broken. But not the hold pots.
 
seems to me that its rolling as well. is your synk hooked up correctally.

Sync hooked up corrct. Positive for centipede, v hold contols rolling correct ?tried. Turned the pot from end to end with little results
 
it can also be negative. pending on where it comes off the PCB. check the schematics and see what pin its coming off of on the edge connector.

i had to change mine when i put a sanyo in it.

Had a k7000 just on it that worked fine........
 
Centipede UR is native positive sync

Centipede CT is native negative comp sync

The difference is in the pinout on the edge connector
 
Pos sync. It produced a perfect picture on the k7000 that is fully working. The one that I need to fix was hooked up the same way
 
you said you checked/replaced the pots.

what about the fly it may be on its way out. did you replace it.

or maby IC2 i think may be bad or have a cracked trace around it.

Didn't replace the flyback ,didn't know it could produce I picture like that. It has the one with the white knobs,heard that one is not too good.
I will order a new flyback and an ic2 from bob. Anything else I should get to adress this problem?
 
i can see a difference in the performance of the chassis. but that's me.

i also have them in stock so i put them on all of my chassis i do, makes me feel better.

plus i have seen some way out of tolerance filter caps. i measure them when i replace them. you would be surprised how many i have replaced that were on there way out. same with the 3 bipolar's.

ordered parts from bob today but i needed a couple additonal pots for the neck board but he said they were discountinued and no good repalcement were avabile because of mirror image
pots that WG had made... what does this mean and can i get a replacement elsewhere?
 
got his one working 100%. are these pots ok or should i get something else? bob didnt have any good replacements. pic three is my assitant.
