WG K7500 issues

[mclovin]

Hello all, I have a wg k7500 and all is good except the vertical position. I can adjust the pot on the remote board but i can not adjust the veto so position just can stretch it larger.

Anyone have any suggestions? I have about an 2” gap at the top of the monitor that I can’t fill.

Thanks in advance

Bump...-anyone?

does your chassis have the vertical hold pot on the main chassis, it should be near the v def ic

[mclovin]

No mine does not have that pot.

i will look at the schems a bit later, so your fault is no adjustment on vertical shift whatsoever but the pot and connection from remote to chassis are all good?

[mclovin]

The connection is good. Not sure about the remote pot. There is only very slight movement when adjusting the remote pot. How would I test that pot?

[grantspain]

you can test the pot with a meter

check Q602 and R619

[mclovin]

The pot is fine. I’ll see if I can figure out how to check the others. Thanks
