    What average user can do is to clean up it. Ensure good contacts - in case of Atari ST it means mostly reseating socketed chips (those square ones in first place), removing rust from pins by need. That must be done carefully, not to damage sockets, which are from stiff plastic. If that helps not, it will need someone with experience and equipment. And may need replacement of some component(s) .

    Btw. the reason why nothing on screen is most likely that it fails at some stage of early HW initialisation.

    Well, that's a shame - I was hoping I could get this working again by just dropping in some new parts, but I guess there was a reason this machine was gutted in the first place >~<

    I've already given it a good clean and re-socketed the chips, so I'm running out of options.

    Maybe the computer works fine and that it is the monitor that can't handle 15Khz that the Atari sends out? I can't remember if it switch to monochrome instead in that case and the monitor works fine at higher resolution and double refresh rate. In that case the computer is indeed faulty.

    The cable I purchased says it can output 640x400 in monochrome, so I assume that means it should work with a 31KHz monitor.

    I recently picked up the remains of a 1040STf that had its PSU and floppy drive stripped out, so I set out on a mission to restore this poor baby. I picked up a new old-stock PSU from Best Electronics, a Gotek floppy emulator, and an ST Monitor Port-to-VGA cable. I finally got all three elements together to test the machine.

     

    The good news is that both the Power and Drive LEDs light up and stay lit up. Additionally, the monitor definitely detects when the computer is on/off, as it gets some signal, but nothing actually ever appears on the screen. Nothing on the board looks out of place or missing, so I'm not sure what the issue could be here. Any advice for making this work again?

    I just happened to find an Atari 1040ST at my local thrift store today, which was incredible, since this was the first time I have ever seen an ST in person before. However, after I bought it I noticed that the previous owner had removed the power supply for some reason. As this is an internal PSU, I can imagine replacement would be difficult. Nevertheless, does anyone know a reputable place I can find a North American 1040ST PSU?

    I have a SCART-To-Component (NTSC) transcoder setup to get RGB out of my Genesis and Saturn, and it has always seemed to work well on my HDTV, but I recently picked up a Trinitron CRT, and when I plug it into that, the image is broken up into messy, garbled, disjointed bars and segments with a lot of color distortion. Is there something I can do to fix this issue?

    It is not special....you can find that really thin tip in those universal type adapters that come with a lot of interchangeable tips. It is 6V positive tip. I used a universal with mine when I had one. I think mine was a Jensen and had a switch on the front that allowed me to select the 6V, but any that have the small tip and can do this should work fine.

    Do you have a link to a place I can buy that adapter? I've tried at least three different universal power adapters, and none of them have fit.

    I have been trying to get my new Dreamcast SD card adapter working on my Dreamcast for a few days now with no luck. I have tried formatting a test 2GB card as well as a 16GB card in FAT, FAT16, and FAT32 formats, and the system recognizes none of them. I am using the latest version of Dreamshell for this. I was sure to put the contents of the included DS folder in the SD card, and whenever I go to the ISO loader, the SD option is always grayed out. I did notice that the LED on the adapter turns on dimly when the system is booting up, and then turns on bright when the first splash screen for DS shows up, and then turns off when the black splash screen appears, and never turns back on again.

     

    Is there something else I should be doing here?

    I have been having a lot of trouble trying to find a replacement charger for my Gizmondo - it uses a very small and specific plug type that is not seen in almost any other adapter, and no adapter I have seen seems to work. So, despite it being a fairly standard-looking plug, it seems I will need to find an official one. Anyone have any suggestions, or could you link me to a universal adapter than has worked for you?

    Hey, everyone! Some expenses will be coming up for me, and my storage space for my collection will be getting smaller soon, as well. So, it's time to let go of some games! I have until roughly the 15th to sell as much as I can, so I'm more than willing to be flexible on my prices. I have a lot of stuff for sale, and the pictures are pretty large, so I just saved them to an Evernote document and posted the link below, just so it won't overload the forum. :P

    It happens from fumbling with the cables while swapping them around to figure out which is which. If you short that ring to tip, it's blown.

     

    Sure, it's possible this didn't happen. Get a C64 video cable and try it out.

    So you're saying that just because the RF isn't outputting audio doesn't mean that the AV port won't?

    If the RF still works, you blew nothing up using the wrong cable. C64's, in my experience, are hard to find completely working. You may or may not need a new SID chip, but you may have better luck getting another C64. If that one doesn't work, then you'll have parts to mix and match between the two to hopefully get one working.

    Well, C64's are pretty pricey, so I think I'd like to try and find a SID chip alone first. :S

    The Master System AV cable has a different pinout than the C64 one, even though the plug may fit. You likely have blown the SID/sound chip by plugging it in this way.

    ...Shit, I just assumed it was a standard connection, given that I've seen the same input on multiple devices. Now I really do need a new SID chip. :(

    I recently discovered that the C64 games I had been playing weren't just very quiet; the sound in my system actually was not working. I believe the problem may lie in the SID chip being faulty, so if anyone has a spare working SID that they would be willing to part with, please let me know. I'm also always on the lookout for cartridge and floppy games for the system.

    I got a C64 a while back that I have never been able to get working quite right. The AV output in particular seems to be an issue. When I have the computer plugged into my TV via RF, everything looks fine, and I am able to load up software just fine, except that there is no sound coming out of the speakers whatsoever. I also have a mono composite AV cable that I use for my Master System that I tried for my C64, and depending on the TV I plug it into, it either makes an incessant high-pitched screeching noise, or displays scrolling black bars across all the TV's inputs. I tried opening up the C64 and giving it a good cleaning, and even re-seated the SID chip for good measure, but to no avail. Any ideas on what to do?
