Title: Wells Gardner 25" 7194 Help Please
Post by: skinz 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

turn this first. the 50/60 pot fixes stuff that looks like this. if not maybe a cap is going.

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

c57   47uF/160v(250)    use 105 degree
c23   47uF/25v
c22     1uF/50v
c18     1uF/50v

Ya, I'm leaning towards bad caps too.
