Ok so I got my Tekken Tag PCB from a fellow Klov'r today.I went to check and was like Wooh hoo finallya working Tekken Tag then I started to really look at the graphics and noticed a problem.Heres my best description without taking a picture because my camera is at home.The graphics of game are crisp but overlapping is these equally distance apart white dots that seem to move together around screen.Kinda like it is slightly snowing or flurring on screen.There are approx. 100-200 of these dots equally distance apart from eachother and all moving together around screen.So I unhook power and hook up the other PCB I got which was SF2 C.E. That powers up perfect no flaws except for the stuff I might not have noticed when I was a teenager in 1992 like Wow these fighter seem to be moving in Slooooow motion well yeah I guess sometimes you forget or fail to realize how things have changed in 20 years.So anyways what could be the culprit?Is it possible these should have been wrapped in pink shipping peanuts?I've heard on here by others to make sure you pack with pink to keep static electricity to a minimum while shipping. I did notice this while unpacking I had small peanuts that wouldnt shake off my hand.Could there be a loose chip that could use some adjusting?Or do these run off different power voltages?I'm at a loss and just need some advice of what I may be overlooking.And yes I did try to adjust the knobs VERT. HORIZ. and the colors and what not.Thanks for your time.

Fixed itself

Musta been something loosey goosey or what not but I pressed the chips firmly and tried again this morning and BINGO Wallah!!!
 
lol, what chips did you push? everything's surface mounted on these. :0

also if you go in Test mode, there's like a Video test part that'll bring up white diagonal lines, there will be software color gain and contrast settings ... there will also be an option to run the video interlaced or non-interlaced.

I forget what I had my color and contrasts set to on mine, it's cool for fine-tuning, but my showcase monitor really needed some adjusting instead. just saying, you shouldn't rely on software, adjust your hardware (as in at the monitor remote board) and then tweak the rest.

I ran mine on Interlaced too, smoothed the graphics out more.

just some more worthless trivia from me. :)
