Wms BB1 monitor problems

[suvasam]

I bought a BB1 slant top sometimes when I’m using it the monitor it’s these lines in it if I open up the machine disconnect the power to the monitor and then reconnect it most of the time it goes back to regular and after that I will get lines again when I disconnected reconnected so on so on what could be the problem I checked all the wires going to it and they all seem OK

Could be a bad. almost bad, monitor power supply.

Could be a temperature problem. Check to be sure any fans are working properly.

Could be the control board (analog board?) for the monitor/display going bad.

Could even be bad Aluminum Electrolytic Capacitors in/on any of the above mentioned items.

Someone more experienced with the WMS BB1 machines may have other ideas and will probably chime in. I haven't worked on the WMS video machines hardly at all. My suggestions are just what I would look at if I were troubleshooting the problem. If you have any of the parts mentioned you could swap them in to see if anything changes, that may give you an idea what may be the culprit.

Just my 2 cents.
