Time Crisis 2 doesnt work

[wolfkrieger]

Hello. I have a Time Crisis 2 motherboard that isn't working. When I boot the machine, the screen lights up with a few lines and nothing else.
I've ruled out the possibility that it's the other motherboards, screen is OK.
There is a blue cable on a chip, I dont know why.

All 8 LEDs light up red, then LEDs 1 through 4 blink.

I replaced the capacitors I marked in red; they were in bad condition. I noticed a chip with a wire on it. Someone fixed it, but I'm not sure what it's for... it could be something related.

Thanks!

if its a twin swap the security module from working side

Lithium cell looks nasty, replace it with the correct one for a start. Looks like 6there's a 16xx in there rather than the usul 20xx.

its the smallest module/board?

Battery gives 3V , voltaje is ok?

Can be a problema wirh battery then doesnt starts?

blue cable dont know why is there

The blue wire looks like a factory mod - the glue spots an neat soldering give it away. If the cell is 3V then all's well. Just appears like the wrong cell for the holder.

security board is marked TSS2, if thats bad it gives similar issue to what you describe

Cell holder is ok, I tested it.. last thing I done its buy new capacitors and change them, I had no good luck..

I have another motherboard ( time crisis 2 again ), begins with some bad graphics, but when game is starded for 30 min aprox this issue is corrected and ok.
why happen this??
bad welding point maybe that it comes ok when motherboard is hot?

Sounds like, yes. If someone can pinpoint you where the graphic rom´s are located, you could visibly check the solder points with a magnifying glass.

A risky move would be to "bake" the board at 200°c for 20-30 min in an oven - I have seen gpu owners did that and then their card worked again. Personally, I would go with checking the solder points.

I finally replaced the capacitors. I was also unsure if that could be the case before reflowing them or touching the chips with a soldering iron, and... IT WORKED! Goodbye graphics issues, it was the capacitors! :-D I had a lot of graphical glitches, thank goodness I saved the board In case the experience helps anyone in the future... in such cases, replace the capacitors and check.

What I'm still doing is with the other board, and there's no image on the screen.

That blue wire on the chip could be a bodge fix, someone might’ve repaired a broken trace or tried to patch something manually. The LED pattern might point to a boot issue or a fault in one of the ROMs or custom chips. If you haven’t already, double-check voltages and maybe reseat any socketed chips.

The blue wire is almost certainly a factory fix as said above. I'm sure i've seen it on some TC2 boards before. I've got a bunch of TC2 boards with various problems myself and i'm pretty sure at least a couple of them have that blue wire. These boards use 12v for audio, 5v and 3.3v for the main logic board. One thing i've noticed that causes them to seem dead is a missing 3.3v supply, I assume you've tested the 3.3v supply (although if it's completely missing the leds won't even light up from what I can remember)? To be honest, these boards can get any amount of things go wrong (and they're all getting on for over 25 years old now!), quite often it's the various ram chips but customs can go bad. If it's a custom then it can be very hard to pinpoint which one it is, and of course it could be difficult to replace unless you're good at soldering those fine legged chips under a microscope! Also, the rom boards can develop problems, I've got a rom board that allows the game to be played to a certain point in one of the later levels, then it locks up and resets. Unless you go to the extent of replacing every rom chip it'd be very difficult to work out which rom chip is the problem because of the way the boards are connected (no access to the roms chips when in use)!

Crikey, those boards are A Surface Mount City
