For units that uses FANS, how do you know the correct FANS CFM for the amount of heat the parts are dissipating? It's often that the designers used the wrong CFM for the FANS used the wrong CFM so the transistors were baking at temperatures that were out of spec plus the electrolyte caps dried up faster than normal, etc. The higher the CFM the louder the fan noise which can cause problems with interferences in the circuit amplifying the fan noises so the signal to noise ratio will increase.

Great video, hope you can help me, the 2 large caps on the amplifier pcb at 19:23 what are their values, mine were ripped off and missing, cannot find schematics on the amp anywhere.

Thanks. They are both 2200uf 25v. Good Luck!

0:34 Boot-ROM B. Could it be that the games you can play are the ones with this particular Boot-ROM (or is it all emulated) in that new device? Maybe some firmware update? 32:03 Rafal Szyja... that's a Polish guy;).

The kit comes with new boot rom code but yes it could still be that is part of the issue. Also, still experimenting but dip sw2 might partially have game specific settings. stay tuned

32:22 More lines when you try to start another game (no success). Maybe fixing memory issues will fix other games not loading?

Also, maybe Manhattan game works as it's smaller/simpler, so it does not address the faulty memory.
