Default Sony U-Matic used in audio mastering repair - DMR-2000

Hi there.

I have a Sony DMR-2000 not working.

It powers but nothing beyond that point.

I am located in the Midlands but would consider driving it to somewhere an hour away from Nottingham.

Information is here: https://en.audiofanzine.com/recordin...sony/dmr-2000/

They are mechanically very similar to other Sony U-Matics and share parts.

Hi Joe,

Welcome to the forum.

It's quite easy to post photos of your own unit. Click on the 'Go Advanced' button, and then scroll down to find the 'Manage Attachments' button. Then you just need to point it to the .jpg file on your computer and the forum software does the lot. Autoscales things too. You can add up to 5 images to one post.

Links to generic photos look less trustworthy than your own as too manu scammers use them, but also if you add your own, it is archiced along with the thread and doesn't vanish if the origins of a linked file gets removed.

I'm not a specialist on this sort of kit but could do some basic testing for you. I'm about an hour away up the A52 near Sleaford, send me a PM if of any use to you, Andy.

Hi and thanks for that.

I have actually had it looked at by a large AV company in Nottingham and they were able to test it and here is what was determined:

"Apologies for the delay in getting back to you, I have been working from home & on site a lot lately. I had chance to look at your Umatic yesterday.
I determined that the carriage sensors are working as expected. In the time I had I tried to determine the reason behind the continued (timed) operation of the cass load/unloading motor after completion of movement. I followed the control path to some buffer IC chips that connect to the control data bus. It is my opinion that this fault is somewhere in the logic control circuit. This may be just a side effect of another fault. It is not going to be a quick investigation especially when following a PDF photocopy of the manual for a comparable model.
This is likely to get expensive and take more time than we can realistically invoice for, and without result if we cannot get the required IC's.
We are also entering our busy period for education installations & I will not have any spare time to continue with this for a while. In this instance I would recommend that we not continue any further and due to this I will not charge you anything extra for the additional investigation work I have carried out."
