Default Sony slv-t2000

I've got a SONY SLV-T2000, where the video8 compartment, will not accept a tape anymore, it was working, and I noticed that on ejecting the tape was very laboured, and although it released the tape in the cage, it did not actually push the tape forward. Although it had retracted the tape e.g. it did not get stuck in the machine, the actual magnetic tape I'm referring to.

But now it will not accept a tape, it looks as if the cage is actually in the inserted position e.g. down.

I really need this to complete one last job of capturing all video8 tapes I have lying around, I've had it from new, and it's not done a lot of work.

I now have the service manual at last, but any pointers would be good.

Thanks

I have now taken the lid off, and it would appear that the tape load mechanism, if that's what it is called is in the loaded position without a tape inserted.

I cannot see anything which appears broken, and nothing which is rattling inside.

But still puzzle why the "metal tray" is in the loaded (down position), and why a tape cannot be inserted.

it looks like the tape loader moves up and towards the door, which would make sense because when working, it would suck the tape in and lower the tape onto the mechanism.

I've got the service manual, but does not give me much help, as to why the load tape is faulty.

hello,

just a guess, maybe the mode switch need some attention, specially the connector.
if it's the F mechanism, it's pretty easy to get it once you exctracted the whole deck.

should be few screws, claws, and some connectors.
but not that hard as it sound

Thanks for the reply.

The service manual refers to an F mechanism, can you expand on "needs some attention"?

need to be cleaned, deoxidized more precisely.
they are easy to take apart to clean track inside of it.
the connector to the pcb is really easy to do.

after deoxidizing, i put vaseline oil (3-in-one brand, for exemple) to protect against humidity.

just check timing marks on gears while remounting.
i did it recently and it's foolproof if i can say that. no real way to do it wrong.

edit : it's just a guess, you may face another issue i don't know.
but usually, vcr who doesn't know where it is mechanically and behave weirdly such as your, really point me to the mode switch.
maybe the tape compartment itself have an issue, but without seeing, it's hard to tell.

For clarity, the "mode switch" is a part which tells the brains of the machine what state the mechanism is in, e.g. loading arms retracted or not, pinch roller engaged or not, FF or RW gears meshed or not etc.

Sometimes they're a sliding mechanism, but I think yours will be rotary. It might look something like this:

They were designed to be replaced when they failed, but as whaka54 says, you can usually dismantle them, clean and lubricate the conacts, then reassemble.

But the "timing" (i.e. physical alignment of everything) is critical - just like the timing in a combustion engine.

@whaka54, @Nickthedentist
Thanks to you both, since learning the word "mode switch" I had a read around, and will disassemble carefully, and check the mode switch and clean carefully and see if it makes any difference.

I've actually found the SLT2000 and F Mechanism service guide, and I've found what is called the rotary switch aka "mode switch"

Genuine Sony 1-692-062-11 Switch Rotary Mode

and there are a few new on eBay, so I might be tempted to purchase some new ones for straight swap, as purchasing some contact cleaner - Deoxit, which this youtube guy uses in the UK is £35+

this video also shows how to replace

https://www.youtube.com/watch?v=q-geC1fndSg

So I may at least try this.

sincerly, you don't need to buy a new one.
there's plenty of solutions for removing oxidation.

tracks are made with a silver alloy (that's why they can badly oxidize) and a silver/copper cleaner on a q-tip will also do the job and are cheap, widely available.
car polish work also very well. all you need is to rinse product residues after cleaning.
then once cleaned, put for exemple vaseline oil to protect against moisture.
moisture is the biggest accelerant for oxidation.

Agreed - new old stock ones may well be oxidised by now.

Once you've carefully levered the switch open, use Brasso, T-Cut or similar to polish it nicely, then apply a little llight oil as detailed above. Don't be tempted to use standard WD-40, though the WD40 'Specialist' contact cleaner (available from Screwfix and similar) is fine in moderation.
