(SOLVED) Another one. Black screen. Fixed some traces and it's working. I started the audio test and at test 6, vertical lines appears. Reset the console and the the menu of the service cart is full of vertical lines. Sometimes they are blue, sometimes they are purple. Replaced PPU2: FIXED! =================================================== Another one (I'm starting to hate these). Tested a few games like mario rpg, nba live 94, yoshi's island. They work fine. But when i run the service cart, i get this: DMA Memory FAIL. Replaced PPU-1 and PPU-2. Problem not solved. So it must be the CPU that's faulty. ==================================================== (SOLVED) Another snes console, another problem. I've tried a few games, none of them works. NBA live starts, but after the copyright is freezes. Started a test with the service cart and get this: WORK RAM FAIL I've replaced the WRAM and the same thing happens. Maybe this one was bad too. Checked all the conection between wram and cpu and cart slot. They are ok. Can it be a faulty CPU? Replaced CPU - problem solved =========================== (SOLVED) Another snes Games works. But I have some vertical lines. But not many. In nba live 94 and mario rpg they are present only on the left side. On the menu of the service cart there are more lines, they look like they are mirrored. All tests are passed with the service cart. The connection between vram 1 and 2 to the PPU1 are good. Replaced PPU-2 and it's working. ============================================================ (SOLVED) I have a snes with glitched graphics. I used a test cart and got this: WORK RAM PASS DRAM PASS VRAM LOW FAIL What does that means? Is it the sram at U4 or the one at U5? Here's a schematic: https://mega.nz/#!QxEgGLiA!pw-SQ6F4EwYdi_RZ0HnlVLDmTSAll5kszVHy0UAP_3E I've checked the following connections for the 2 sram chips and they are good: data and address lines to S-PPU1 data lines to S-PPU2 EDIT: It seams the LOW sram is the one at U5. More simptoms here: http://projectvb.com/nss/logs.htm I've replaced the sram and it's working!!!
