oh I missed that post on my phone mayhem, I already have it apart for cleaning i'll check it real quick
edit:
its a 6567 HOWEVER...
its a gold chip!
and while reading up on the best way to get the metal top off I found that the gold chips are some of the earliest.
if the sticker on the bottom edge of the board is a serial number then this is a pretty old one.
the number on the sticker is CS00053809
edit#2:
looks like I might have to do some digging into this. visually everything was ok.
powers on but no video over RF channels 3 and 4. not using a switch box just going directly RCA from the system to the coax to rca adaptor I got from radio shack that I use for the Atari stuff. the Atari stuff works, this still just gives static
EDIT#3:
never mind, apparently my 19 inch sony trinitron's tuner is not any good any more.
I took a rca cable and rca to coax adapter and plugged it into my brand new 40" hisense lcd "monitor" and it came up no problem on both channels 3 and 4 and new LCD TV's are really picky about the signal coming off of these sort of things so I am almost certain all the problems I had are solely that tv and the fact its tuner is going bad...which sucks because it was the perfect size and has excellent picture quality.
i might attempt a tv repair but i donno. good CRT tvs don't show up here, just a lot of cheap crap or really old unusable stuff with the middle gen stuff (i.e. no coax or rca hookups)
any way. getting minor interference that goes away when i touch the rca cable. possible ground/shielding problem but there is a 3/4 local channel that might be the cause aswell.
i'll look into making a scart cable (yes i have a scart tv that's NTSC) with a cable i found for some audio equipment at a goodwill.
its got the scart male end with rca females on the other side
