Display issue octane emxi vga

Unread postby bvgoor » Thu Mar 15, 2018 2:57 pm

Hello all,

After a bit of advice, just starting to install an octane using a 13w3 to vga adapter and experience some artifacts on the display, any idea what this might be?

Thx,

Bas

hmm... try and eject and carefully clean the connectors (both on the motherboard and the Video Board) and reseat the Octane's Graphics Module!
If it doesn't get fixed, then it probably has to do with the Video Board's memory, I guess.

Looks like a dirty connection or gfx hardware issue. Had an SSI card that did the same, nothing I did could save it. Try and clean the compression connector with compressed air and reseat the card.

Have you got TRAMs on the board?

I have had several 13w3 to VGA cables cause the effects you are seeing. Try a different cable before tearing the machine apart. Here is an example.

If the thing isn't on fire it's a software problem.

TRAM problems can cause repeating patterns in the display output.

Before you pull the board out, run the integrated diagnostics from the PROM menu (option #3).
If it fails the diagnostics, pull the gfx board, unscrew the two nylon screws in the metal bracket outside, and re-seat the two TRAM modules (eventually clean with some alcohol, but don't damage the connectors). Fix the TRAMs with the nylon screws again.

Worked for me (twice) in the past to revive a malfunctioning MXE (= emxi) board. If it still fails the diagnostics, you can always try without the TRAMs, that would make it an ESSI graphics, though.

Sadly don’t have another 13w3 at the moment

It has to be a faulty GPU. Or! A dirty connector (either on the midplane or on the GPU side)
Can you borrow a simple SI Video Board from a member and try with that?

Do you need anything larger than 1280x1024 to test with? I have a SE card you can borrow for testing purposes.
