Neotec NT-2702 Horizonal hold issue - cap/ cold solder joint related?

I have a Neotec NT-2702 in A Roadburners game and it works fine, but after it warms up, it appears that the horizontal hold fails and the screen distorts.
I plugged in a VGA monitor directly to the video card and it never happens. If I let the monitor cool down and try it again it will be fine for a while again.

I noticed a bit of hissing coming from the left front of the chassis. If the screen is distorted and I bang on the chassis, the screen will come back normal. If it is normal and I bang on the chassis, it will distort.

I am thinking that it has some cold solder joints and maybe need a cap kit because one cap in the section I can hear noise has some brown residue under it.

Any thoughts?
