How to Troubleshoot (and Fix?) an NBA Jam Arcade Monitor! K7000 HV Shutdown & Bad Voltage Regulator.

[@K1NGARTH3R]

Great fix, thanks for showing this steps in this level of detail. I've never checked the B+ before and this shows how easy it is.

[@overtimearcade]

Thanks! It's not too difficult, but the process for checking the B+ is a bit different on each type of monitor. Peter has good tips for that here: www.arcadepartsandrepair.com/tech-help/monitor-b-settings/

This was really fun to watch while I worked on my NHL Open Ice! :D Thanks for making this and congrats on getting the monitor in working order!

[@overtimearcade]

Thanks! Working on monitors is fun! How's everything going with your Open Ice?

[@Ziondood]

@@overtimearcade It's been going okay! The cab was mostly gutted so I've been tinkering and learning as much as I can and just finally managed to test out the monitor last night and was ecstatic!

Nice work!

[@umtrainer-8431]

Enjoyed the video. About to tackle a monitor repair myself. Thanks for being so descriptive and explaining where you got parts and flow chart. Will be looking for the flow chart for my monitor.

[@overtimearcade]

Thanks, you’re welcome, and good luck! What kind of monitor are you working on and what are the symptoms?

[@tvtime1505]

Nice job with the video. Hey guyzzzzzzz, we are in the garage.

[@overtimearcade]

Thanks! It always cracked me up when John would say "GHEY-RAJ!" 😂

[@carlosfields9937]

I agree I rather know exactly what was wrong rather than shotgunning it. Did you happen to bench test the voltage regulator ?

[@overtimearcade]

Not yet, but I’ll test it before discarding it. I usually keep all of the old parts, etc. from my projects until they’re 100% done.

@@carlosfields9937 It also helps remind me what I’ve done, and just in case I screwed up with my diagnosis and it’s still good!

Can you possibly share how I just the vertical height on this monitor? Mine plays a little too tall and I can't seem to get it adjusted. I am unsure if I'm just missing something obvious.

[@overtimearcade]

There should be a VERT SIZE adjustment pot right on the back on the chassis PCB (or possibly a remote board). If that pot isn't making a difference, you could have an issue with the pot itself, or a cap, or something else is wrong with the monitor. Good luck and let me know how it goes!

[@michaelhannaman2474]

@@overtimearcade thanks. I will check again. I didn't see anything labeled vert size on the chassis even though I could adjust the horizontal from there. Maybe I just need to go slow a tweak each pot until I find the right one.

[@overtimearcade]

If you can determine the specific model of monitor, you can refer to the manual to see which pot controls vertical size, even if the labels have fallen off the chassis.

hey overtime you should go watch Bill Heatherlys Midway Sea Raider cabinet restoration, its pretty sick

You gotta be careful showing anything from Randy he will copyright claim everything possible

[@overtimearcade]

Good point!

[@WayneSylv]

I’ve talked to him about something I posted on Facebook and the ended up buying his big blue book of arcade repair lol

[@overtimearcade]

Did you get much use out of the book?
