Monitor repair, Trying to learn

[Boyroy]

I have a Capcom Bowling game and the monitor is blank. Can still hear the sounds as if the game is working, just a completly blank picture.

I am trying to figure out how to see what is wrong. I could not find any lose connections. The tube does NOT have the "glow" and DO NOT know how to test to see if it is the tube or no power to the monitor.

I AM NEW at this and was hoping someone had sympathy and the time to point me in the right direction. I could really use a step by step guide and didn't know where to start.

I have 2 "other monitors (both have wavy pictures) and eventually want to be smart enough to repair as well.

Looking for a mentor of sorts. I enjoy repairing the Arcade games but have never had to do ANY monitor repair or replacement.

Please Help!!

Thanks,

Boyroy

Well, checking to see if the monitor has power is easy enough.  Use a multimeter and check the power leads.  If there's current, great, if not, check your connections.

Do you hear a high pitched whine?  That would be your high voltage.

When it's powered up, do you hear the distinctive '*thum*' sound of the monitor coming on?

Peale,

Thanks for the reply on my "blank" monitor problem. There is NO high pitch whine NOR the "thum" of the monitor coming on.

I've read about grounding the monitor (and the dangers of not grounding) but have never actually done it. I understand the concept but do not know exactly which part of the montor to "ground".

I was a little nervous checking with my multimeter as I didn't want to get shocked. Do you have any pointers for a true beginner?

Check the fuse(s), too.  If a fuse is blown, there is probably a good reason why.  A bad flyback and/or HOT will normally blow the fuse, but it could be something else, too.

See if you can identify what monitor you have.  The chassis probably has a tag or label (not the label on the tube!).  When you know what monitor you have, you can then try to track down a manual for it and start some troubleshooting.  www.mikesarcade.com has lots of manuals in PDF format.  Say you find out you have a Wells K7000 series monitor, then do a Google search for "K7000 flowchart" which will also give you lots of troubleshooting info if you can find one.

Good luck!
