WG K7500 golden tee fore problem
« on: September 05, 2015, 05:27:15 pm »
Hello, just picked up a golden tee that has a bad monitor wells Gardner k7500. When first powering up I have a screen with squiggly lines that from what I have read by others may be a sync issue. Then while powered up if I disconnect the power plug to the monitor and plug it back the screen comes to life but there appears to be an issue with the proportions ( have read could be horizontal deflection issue?). I have done lots of googling and reading and I am just very novice with this stuff so I am having a hard time understanding. I have replaced most of the caps on the board (some I couldn't find locally), and I have touched up solder in lots of the connections and there has been no difference.  I have attached a couple of pictures of the screen as described, not sure if the will upload correctly or not.

Hopefully one you monitor gurus can point me in the right direction, keep in mind this is my first time messing with anything like this so I'm easily lost with the lingo.

Thanks in advance!

looks like horizontal hold and vertical linerarity needs adjusting
i don't think k7500 have a v.lin pot so the fault will be with the vertical ic circuit-probably a cap,infact all the faults you are seeing could be related to leaky caps

Maybe one of the few i didn't replace is the culprit I guess. Where is the best place to get a complete cap kit online for this ? Thanks
