Wells Gardner 25" 7194 Help Please
« on: January 23, 2011, 06:12:51 pm »
OK so my monitor looks EXACTLY like this guys - I have a WG 7194 just like this guy and I have the EXACT wavy line at the top of the screen.  His problem was never resolved properly.  I don't have a Chassis to replace mine with and was wondering if anyone else has seen this problem.

Thanks

50/60 pot doesnt fix it either - possibly a gentile combo of the two - I'll try those 2 again - so it's a "DON'T TOUCH" on the coil H-Size pot?

I've turned everyhting else
