Curvature at top, can I adjust this out?

[TravistyOJ]

Picture says it all.  I actually have this happening on two monitors.  A WG K7000 and a Nanao MS8-26SU. Is there some adjustment I can make to make this go away?  Thanks

[Q*Bert_OP]

Try adjusting your vertical hold, if not try a capkit. What mofel of K7000?

[TravistyOJ]

Tried adjusting V hold, no luck.
This monitor just had a cap kit.  It is the 25" K7000, not sure of the exact model number.

that picture you posted,is that your convergence grid,if so why is your blue higher up?,you also say you have two seperate monitor doing this exact problem-is that two seperate tubes as well?i am trying to work out if you have a monitor,tube or game board issue.

[TravistyOJ]

That is my convergance grid, it has a blue border.  All of my colors are displaying properly.  The problem occurs on 2 seperate tubes, and occurs with different game boards as well.  Thanks for responses guys.

Yeah, you've got some curl there.

You might be able to adjust it out if you work at it, but it might be a cap.

And I don't mean an electrolytic cap, either.  We had a K4900 do the same thing, couldn't sus it out.  Finally sent it out.

Not a *huge* issue, but annoying.

Yeah i was just kind of testing the waters to see if it could be a simple fix, but I can live with it.

its a long time since i worked on the k7000 series monitors but i am sure there is a pot on the chassis that sorted this problem out,the only pots not to touch on any chassis are the ones that are sealed with paint or glue,otherwise muck about as much as you like

...the only pots not to touch on any chassis are the ones that are sealed with paint or glue,otherwise muck about as much as you like

Actually, a recent monitor tech class I attended recommened *removing* said glue.  It expands with heat, and over time will knock those settings completely off.

That said, I would only recommend someone that knows what they're doing attempt that, because if you adjust your voltage too high, you'll blow your monitor.

yep i know what you mean,i have worked on monitors for 20 years and muck about loads with the pots-sometimes on an older chassis a pot can get a bit tarnished if sat in one position for a long time thus causing the odd issue like the one mentioned-it is very difficult to cause major problems to your chassis by adjusting the factory presets,i would think the most you would do is over volt and cause a psu trip-but all chassis are slightly different so dont quote me on that for example a pentranic has a 25volt pot for the frame chip,there is a common fault on that chassis that causes a frame lapover at the top and by adjusting that pot you can resolve that issue but the underlying fault is a leaky cap on the 25v circuit that smoothes the voltage-this has to be replaced because over time that cap breaks down to an extent that the 25v goes high thus causing your frame chip to burn out giving you a frame collapse.so i think what im saying is if your not sure dont touch.
