Title: G07-CBO monitor help
Post by: centipede on June 12, 2012, 01:35:53 pm
Hello, my name is Tanner and I've been collecting arcade machines for 2 years.  This is my first post on this forum.  I am posting here because I need help with my G07-CBO monitor I have in my centipede cabinet.  The problem is is that the monitor will not come on.  The catch is is that I CAN get it to come on by plugging in and un-plugging the monitor in the back.  The board is fine, and the monitor gets the right amount of power.  I have been recommended to install a capacitor kit.  Would this fix my problem, or is it something else?  Thanks in advance!

hi
any or all g07's/g08's require a cap kit
it is that simple
also please chk in our fourm's for post's by ken layton
now on to how u are starting,this is called suge starting
what u are bascily doing is charging the start up circuit
so in your cap kit get the :main: filter,once this is done
chk your b+,as u have have a damaged b+ reg circuit

Ok Im having a little trouble understanding what you are saying, but should a cap kit fix my problem?  Also, should I replace the hot?

what he's saying is your basically kickstarting the system because the caps are old and dry.

it starts up but shuts down because the load of all the dead/dying capacitors is too much (caps act like a dead short until they are charged up) old dry caps will take longer to charge up (if at all)

unplugging and then quickly plugging back in again, the first surge of power before it shuts down gets the caps charged up a little bit (enough so they aren't a total dead short any more) and then the second surge is enough that the power starts up and the monitor comes on.

the g07 monitors are 30 years old. the caps are going to be old and dry. Replacing them is going to be your best bet.

The rest of the monitor works, so just replacing caps will be a good enough start. Once that's done if there is any other issues, come back and we can help out sommore.

be aware some cap kits don't come with the big main filter capacitor. You are going to need that one too.

Does this main cap need to be replaced?
