More Triforce3 fun!

A friend's Mario Kart GP was throwing an error 26 and the fix was recapping the TF3 base board using the cap kit from console5.com. Two weeks later his other MKGP threw the same error code and I had another cap kit to do the work. When I did the previous board I wrote down every cap location and value so doing it again would be faster.

I wasn't paying close enough attention because after pulling all the electrolytic caps from this base board I notced it was slightly different. The common version of the TF3 base board is TEC-1VM but this one is a TSK-A. Some of the cap values appear to be the same based on board location, solder pad size and proximity to other components but others have me stumped. I am most concerned about C15, C20, C21, C29, C30, C31 and C33. C15 and C21 are probably 470uF based on solder pad size. C29, C30 and C31 are most likely video related and the Sony CXA2067 datasheet has 47uF caps on the Vcc pins.

Not much info on the TSK-A Triforce base board. It might be an earlier version given the bodge wire and lack of a second voltage regulator. I couldn't even find a reference photo with cap values.

First photo is of my TSK-A with my best guess caps in place. Second is my notes as to cap location and values.

Sooo - does anyone have a TSK-A cap list or a clear hi res photo with readable cap values?

Since I never got any responses I had to poke around with a DMM. After said DMM detective work I realized which caps were 5v and 12v filter electrolytics. Installed replacement caps and the game is running normally.

First image is the revised cap list for my TSK-A base board.

Second image is the power connector board which is marked TSK-A.

Third image is the same power connector board from a regular TF3 board which is marked TEC-1M.
