[SORTED] Out Run Screen Interference

[Jodo]

Hi all,

I've just installed a NoS WG K2703 into
my Out Run Upright, hoping it would solve two issues I had with the old screen:

1) Tube burn

2) Interference

Well, the new tube has obviously solved
the burn issue BUT the interference remains; if anything because the tube is
new, it's more pronounced

The chassis is earthed to the prime
earth point in the base of the cab.

This isn't the camera for once; this is
what I'm seeing on the actual screen!! Any
ideas? It makes the game almost unplayable

Thanks in advance!

I've wired up R, G, B,
GND and -H SYNC as per
the following diagram; to be honest the pin-out is identical to the old screen
(a WG K7000), so the connectors went straight on; if this is wired up wrongly
then the old screen was too:

I had this type of thing once. I was advised to replace all the signal wires with exact length new, and it all went away. It didn't help they were routed with (and not across) the power cables. Also add a ferrite coil.

Hope it helps.

It was the earth! The WG comes with an earth cable that runs from the metal chassis casing. All I did was attach it to main earth in the cab. Anyway, when I removed it, the interference is 100% gone.

Now the picture is factory fresh! Very chuffed indeed!
