Macintosh SE FDHD 0000000F and 0000000D error

How to fix this error? Does anyone have experience?

Are you asking about 0000000F / 0000000D or the error you posted an image of?

0000000F / 0000000D is an NMI early in the boot process, before a debugger is available. Check that the interrupt/debug button on your board isn't stuck in, for starters.

0000000E / 0000FFFF is a data bus error, per https://udcf.gla.ac.uk/~gwm1h/Error_Codes/Sad_Mac_Codes.html. It looks like something is knackering the bottom half of your data bus. That page recommends starting by swapping SIMMs around, which is as good a place to start as any.

This can also happen if the computer is misconfigured for the amount of RAM installed (there is a pair of jumpers that sets how much RAM is installed, and one must reconfigure them if there's more than 2 MB of RAM installed (I think)).

So make sure they're properly configured for the amount of RAM you have (there's a legend in the silkscreening surrounding the jumpers that tells you what they should be set to for several different RAM SIMM combinations).

Now turn on the screen

After I press the reset button, the error 0000000F 0000000D appears

If you press the interrupt button, the screen will be blank for 3 seconds and then continue to be blurred

I think you may be confusing which button is reset and which is interrupt? the F/D error is the normal response to an NMI, for example from the interrupt button being raised early in startup. So that bit sounds like it's actually working.

What is the relationship between the garbled screen you just posted and the error in your first post? When do you get one, when the other?

The checkerboard screen could be due to a damaged AB to LB cable or bad solder joints on the analog board. Remove the bucket, then, while avoiding the picture tube, turn the power supply on. Move the cable that connects the logic board to the analog board. If you get a startup beep, then normal video (or the initial Sad Mac error code), you've problems with the cable. Since the board is responding to the interrupt switch being depressed and throwing up the NMI error code, I suspect it's probably a flaky solder joint.

The initial symptom was 0000000E 0000FFFF, after I replaced the LS245, the symptom disappeared and it turned into a checkerboard screen. Or sometimes the gray screen, whether the ringtone is activated, is always in the state of the gray screen

There should be no problem with the cable, the current situation is a gray screen after booting, no boot bell, and no question mark interface on a floppy disk.
