Title: Plasma Meters
Post by: Jermbob on June 12, 2013, 08:41:41 PM

All of my plasma meters stopped working.  "Number bar" and tape/group/etc. status, at the top, work, but everything else is down.

Any ideas?

How's your 250V feeling?

It seems to be fine.

Have you checked that tension is really reaching meters?

Check all the boards on the 250v. They run really hot and eventually fry, especially the E75.

Also check the ribbon connection that runs off the main plasma distro board to each bucket.

Get a tech in. 250V DC are not something you want on your skin...

If you dont have a tech and you dont know what your doing by all means PLEASE get a tech, That is 250v you are dealing with behind the console and it will do more than make your hair stand up. Check your 250 lights on the supply and there is a 250v power switch on the front of the supply make sure that is on even if the light is on. If you do know what your doing start checkin the E75 board, check the big green resistor (R9, R10) after that check all six trannies, those were what usually failed on boards in my town. After that ask yourself how old the caps are on the other boards, many many problems are solved by changing out old tired caps, especially on the plasma meters. Just my 2 cents
