Hello, I've recently replaced all 80 smd caps on a Sega PAC for the laseractive. Very pleased with the result, have been working on my soldering skills for a few years, this was by far the largest job I've attempted. Luckily the caps weren't that bad, most had started leaking but not to the extent of doing much damage. By some small miracle all the caps were removed without lifting a single trace, result!
The laseractive is now almost fully functional... LD movies and mega LD play just fine, have a few movies and one mega LD game (Pyramid Patrol) all working without a hitch. The CD drive is also fully functional, audio and JPN mega CD games play perfectly. I've successfully changed the region on a few USA games and they are working fine as well (using SCDToolz 3.55).
The one issue I have is cartridge based games, all I get is a black screen when powering the unit with a cart connected to the PAC. I had originally thought this was due to me having a JPN region PAC-S1 but no JPN cartridge games. The mega CD games I have running are all JPN, USA/PAL discs don't work without altering region. So I ordered a JPN cartridge game, this arrived today but gives the same black screen as my PAL cartridges (I'm in the UK so everything easily available is PAL here). I also have a mega Everdrive and this also results in a black screen... weird.
Both PAC cart connector and cartridges have been thoroughly cleaned with no change in behavior... same black screen. I'm now lost as to what to try next... any ideas??
Have attached some pics of my soldering wizardry
