I have a 1987 27" Sylvania tv and it had some cold solder joints which I
fixed. It works great except the picture gets slightly brighter and dimmer.
Could this be caused by the wire going from the flyback to the cathode? When
I first put it back togeather I could hear it arcing a little like the
suction cup wasn't all of the way down. It doesn't make a arcing noise
anymore.

The model number of the tv is RNH4601 WA01
The Chasis model # is 26B1-06AA
Manufacture date October 1987
