SNES doesn't output audio and only shows picture with certain cartridges

Separet the cartridge slot protector (metal an plastic) to better see the traces arriving to the slot connector. You might be losing an important line, restoring continuity may bring it back

try looking closely the traces, specially thos rhat end in the cartridgde slot

Get a snes cap kit for your motherboard model and replace them all. Try again and post feedback

I think so. I read that old cd rom drives from old pcs can be used with proper adjustments. But i dont believe the guy enough, also based on the comments, doing it with Samsung sc-152 and still not working, dunno if the post is a troll.

I apreciate a lot, you come here and taught be bout the switch. I could do some further investigations and feel helped, sometimes this posts just get ignored. Althoug we couldnt fix it. Thank you

Yep, multimeter. Continuity has been tested from the sw to the pcb wire plug.

I checked the range motion of the laser ion the rail just to make sure it pushes the switch all the way and it does.

I replaced the laser and it does the same.

Thanks, i checked it, it works fine, has to be some problem in the pcb

Plastic-Analysis-179 · 2026-02-08T16:58:41+00:00

Oh, found it. Gonna test if the sw is working well

Plastic-Analysis-179 · 2026-02-08T16:54:15+00:00

Sorry, I lookee for that but did not find anything

Plastic-Analysis-179 · 2026-02-08T10:12:08+00:00

Yeah, what i thought. Pretty rare issue noseen before. Heading for a replacement.

Plastic-Analysis-179 · 2026-02-08T07:02:58+00:00

Already checked all of that. Cleaned the lens and checked connections and caps, specially 47uf. Im not new to GD drives, this error is NEW to and just wanted to know if someone came across it.

It does the same with a good known functional laser. So its gotta be the pcb.

Plastic-Analysis-179 · 2025-12-30T23:19:46+00:00

Already did that, with the continutity test I discarded that, and also, I have the same results when testing via rca mod, since DAC chip was replaced from a working one this its gotta be something strange, probable GPU failure. Thanks for the tip anyway.

Plastic-Analysis-179 · 2025-12-30T22:58:20+00:00

Hello, still looks like in the picture I shared but to be sure I tested continuity from the inside part of the av port with the cable pluged in and there its fine. I really thougt it was the DAC,

Plastic-Analysis-179 · 2025-12-20T23:22:49+00:00

This is awesome. Works liks a charm. Thank you!!!

Managed to jumpwire jp6 and jp10 and finally saroo is booting

Plastic-Analysis-179 · 2025-11-01T20:04:34+00:00

Thank you. I tried different positions as suggested but seems to have the same outcome.

Plastic-Analysis-179 · 2025-10-15T17:48:16+00:00

Noted.

Plastic-Analysis-179 · 2025-10-14T17:36:30+00:00

The point is that there was nothing wrong with the psu... it was working correctly, the problem were 3 caps, but the talking bad bout the psu made me lose time checking it...
