PC Engine PI-TG001 issues

I had a similar issue and in that case bending the flatband cable in one direction would make a proper contact!

So it measured correctly when I tested it, but if you bent it (accidently) in the other direction it would not. And it's even worse with these more wire like flatband cables!

I see.  Still doubt that's the issue if it ohmed out ok though.  Won't hurt to replace it but it's quite a bit of work.

As long as it's only work I don't really mind.

Replacing one of the proprietary ICs is much more of a problem. Especially getting it in the first place!

if the meter said you good, move on to checking those pins to the 6280
bad traces are about as common

OK. Will check those next.

Checkups complete!

- connections between card slot and pcb
- connections between pcb and ics 101-103
- resoldered ics 101-103

Same result. My guess: one of the ics is a goner!



You can actually HEAR the console initialising if you turn the volume up during start! But after a moment it will obviously stop. So either something from the hucard's side is "missing" - or something from the console side not responding.

black screen no sound?
if you have rock-on try it as it doesnt need pixel clock for sound
im guessing the ram chip on the card slot board is bad

No, sorry, it's a white screen!

[thesteve]

white screen could still be almost anything
