Unknown motherboard trouble.

[T-Berg]

I have two n64 motherboards which is rigged for use in portables. Both have cart slot relocations. They are both hooked up to ps1 screens. When i turn the systems on there is no response. Despite them both having worked before. It seems it is the same problem. There is absolutely no signal from them. Not audio no video. At the moment i use a PTH 08000 which delivers 3.09- 3.11 v. I tried with 3.24v but no luck with that either. So i dont think its undervolted. Could it be a problem with the amperage? I have also tried more than one jumper/expansion pak. Any help at all would be greatly appreciatedI have also charged the batteries so its not that either.

1- give all slots a goof bj
2- try with the original power supplu
3- check all cart slot connections
4- try with another game
5- test both psone screens
6- leave all power off them for a day and try again
7-...their dead?

I had the same problem with mine. Try using thicker wires, or if you still have the power plug, solder it back onto the board and test it with the original power supply. If it works, relocate it with the wire that you're using for power. If it doesn't work after that, then you need thicker wires.
