SNES 1CHIP BOARD RESURECTION

hey all, wondering if anyone has any suggestions on fixing an SNES mainboard. i picked up an SNS-CPU-1CHIP-02 board off of ebay that was known to be bad because of no power jack. i have replaced the powerjack and completed a cap kit and am still getting no video or audio except the occasional glitch. i even posted a youtube video showing the board off and the video/audio issues i'm having. if anybody has any ideas i'd love to hear them. you can view the youtube video here ->

 

Is the cartridge slot clean? Are there any broken traces in between the cart slot and the video chips (VRAM, PPU, etc.) and/or CPU? Which CPU is it? Is it a S-CPU A or B?

 

i cleaned the heck outta the cart slot with a soft cloth/plastic card combo with both alcohol and electronics contact cleaner so it should be clean. i haven't spotted any broken traces but i guess i gotta go over the board again. here are some pics i took of the board. i think these were taken before i did the cap kit but after i had re-attached a power jack and output sheild.

Hard to say what is wrong, could be cold solder on one of the chip, or a bad part.
