Hard to see the board damage unless you lift a Cap to see under. I would recommend that you try to recap and as you do that, visually inspect. Goodluck, very tricky to follow the way that JRC psu works.
I'm not selling this; just want to raise awareness of the auction.
This one will be interesting to watch, because this seller previously auctioned this exact machine. It sold for about 100$, and the seller appears to have cancelled that sale and immediately relisted...
I did replace most or all of the eletrolytic caps. I found spares that I could make work. I did not order any new parts this time. Kind of a hack job.
Do you have the schematic? It is posted at minuszerodegrees.
I personally used a 12V supply from my junk pile. It was a toshiba laptop supply. The trick was getting a barrel to fit, and polarity check of course. There is an ebay auction right now that has a z171 qith a small wall wart. Maybe you can see a part number in the image.
I recently repaired a T1000xe to a working state. I used information I found online regarding T1600 if i recall correctly.
It was very involved. I had to replace caps and some semiconductors...both ics and psu parts.
I think these machines share architecture for the most part. There is a...
No, little board changes that are fixes to problems get added in the factory after the pcb is built....those are barnacles. For your hardware to require reversed bits for video means you machine has inverted video as a default relative to mine. Very odd. But whatever works.. not the reason...
sounds like you have a good ram board now.
you could try pulling the CMOS RAM (to reset contents).
I guess the CMOS RAM is one are of potential problem. what if you have a missing address line at the cmos ram?
Also, I would bet that even with a bad A13, you would pass ram testing. But you need...
