There should be one on the top right, pretty much right under the picture tube. It's almost impossible to adjust with the monitor assembled and switched on.

Yes. There actually is a pot for horizontal hold on the PCB. Adjusting it fixed image. The problem comes back after a while though. Maybe the pot needs cleaning or replacing. Either way, the problem is connected with that pot.

Yes, everything is PAL. I tried adjusting the H-HOLD pot R225, but it didn't fix it. When connecting an Amstrad CPC, I can see the picture, but it's distorted and shaking about. When connecting the Atari ST, bascially nothing is visible on the screen except a few faint lines. What could the reason be?

Unfortunately this didn't work either. Just to test it further, I connected my Amstrad 6128 to the monitor, also using the SCART adapter, but it too doesn't sync. You can see it would only need a touch adjustment of the horizontal hold. I wonder if there's a pot to adjust on the inside?

I got a Commodore 1084-D1 monitor which I'm trying to get to work with my 1040 STE, but it won't sync. The monitor has a 9 pin d sub port and I have a 9 dsub to SCART adapter for it. I have a monitor cable with a SCART plug. I tried to make my own cable (RGB to RGB, GND to GND, Atari pin 2 (sync) to 1084 pin 7), but it's the same result, just distortion on the screen. All the other computers I've thrown at the 1084 work (C64, C128, VIC-20, Amiga, various arcade boards), but not the Atari. Am I missing something here or is it not supposed to work?

Awesome, thanks! By the way, is there a convenient way to extract individual files from .ST disk images?

What's the best way to transfer large files (ie larger than 800kB) to a Megafile HD with an Atari ST? I have a Gotek floppy, but it too only can do disks up to 800kB large. Also, how can I transfer individual files? Disk images in .ST is no problem, of course. But how to transfer .PRG files, say?

The image looks like on the attached picture. It's flickering, like as if there's a sync issue. I note that the picture is spread out on the entire horizontal width, which is not supposed to be the case, of course. I recapped the board and neck board, without any difference. The board is looking clean otherwise, with none of the nasty glue spread out, which I've seen before on other monitors. There doesn't seem to be any pot to adjust H or V sync, and the other pots don't seem to have anything to do with this problem. Many of them are stupidly placed underneath the tube. I haven't found a place where to check B+ and I also don't know how many V it's supposed to be. Any ideas what I could try?

I put the drive on top of my PC, where it's being warmed up to about 40 degrees. I put the drive in the STE and it starts right away. It's all SMD parts on the board, apart from the connectors. I'll see if I can see anything suspicious.

I tried the other STE's drive in the one I'm having difficulties with, but I also tried the faulty disk drive in the working STE, where the drive also didn't work. It's strange though: when the computer has been on for 15 minutes or so, the disk drive is working without any problems. Which part needs time to "warm up" and why?

I have a problem with the disk drive in my 1040 STE. On startup, it spins up alright, but the head just jerks back and forth 1mm. When I move the head towards the inside by hand, on startup the drive moves it to the outside but it doesn't move from there. I cleaned and relubricated the spiral thingy. There are two caps on the PCB which looked dodgy and I replaced those. While playing around with it, the drive suddenly was working and I thought all's well, only for it to stop working again next time I started the computer. The drive is a Sony MFD110-003. I put in a known working drive from a different STE, and that's working just fine. Any ideas what I could try?

I have an 1050 which doesn't eject the disks when turning the knob. There's this little metal notch (see pic) which, when pressing on it, makes the disk shoot out, so it appears there's enough tension on the spring. Is there something else I can adjust or lubrify to make the mechanism work as intended?

The trouble is that the startup sequence doesn't complete anymore. When switching on the drive now, it doesn't stop spinning, even without a disk inserted. And the LEDs don't come off anymore.

So I found out that the 810 does not spin the disk when one is inserted. I did notice that ID 1 was not correctly selected (I wasn't very clever in checking). Once ID 1 was selected, the drive now boots up when switching on the computer Initially, it was loading a disk fine, when all of a sudden the head wanted to go to the outermost track and was rattling around there. When I switched the drive off and back on, the head now remains there (or moves there if I pushed it back inwards before switching on), the drive is spinning and both LEDs are lit. So now something actually properly broke?

I don't know the behaviour of these drives, it's my first one, as mentioned. But isn't it true that when the flap gets closed and a disk is inserted, it starts spinning it immediately, independent on whether the write protect tab is on or off? Also, if I half way insert a disk half way, so that the sensor is blocked, the drive never spins up, or does it?
