Water is a great damaging factor for tape drives. I know you can disassemble the drive (almost) complete and clean everything you can see. Not only should all moving parts and rollers guiders be cleaned, but also the logic boards and the cables and connectors. You are not allowed to remove any of the rolling parts, because you wont be able to readjust them without calibration tools. Then it should be reassembled after cleaning. Also use a cleaning tape several times, to remove all residue of the cleaning fluid. There is special cleaning fluid for things with water damage, but the heads and guiding system can be cleaned with clean alcohol (no spiritus)

For what it is worth, I found an old manual of the drive. Because it does not have a normal URL I put the link in the text here:
ftp://ftp.hp.com/pub/information_storage/software/ltt/2-wd11.pdf

Don't use any of the storage tapes, you have your data on, because you could damage the tapes. In the end, perhaps you have to buy another tape drive, to restore your data so save the tapes, till you are 100% sure the drive won't eat the tapes.

replace ALL belts in the deck (there are 3) the deck is sensing that the tape reels aren't moving and protecting it. that should solve your problem. do not use elastic bands, they will foul and destroy the gear driving the capstan.

Start to pay and shuts down


Someone is going to have to look inside, the mechanism that moves the tape has a problem which will cause shutdown, possible belt or mechanical issue.

With cover off and a tape inserted look down at top of cassette and engage in FAST FORWARD----do reels in the cassette move quickly or not-----Sometimes if a worn belt or drive idler running the tape back and forth with fast forward and rewind will cure the issue for a short time----no movement equals no motion and unit should shut down.

My Philips model DVD750R/17 shuts off when playing a VCR tape after about 15 minutes. Why?


The most likely cause is a problem with the mechanism that moves the tape(when played a bit more weight is on the takeup reel.

Someone would have to open the unit so they can see the reels moving---watch to see if it begins to hesitate when further into the tape.

A trick that can help to see is put a fully rewound tape in and hit fast forward--let it go all the way to the end and rewind--if unit does not stop after doing that see what happens in play.

A worn drive unit that moves the tape can sometimes get better after run this way.

The PLAY function of my Cassette desk doesn't work anymore


Well two things have to happen to make tape move in a cassette deck. One is the Capstan shaft has to rotate and that is usually a belt link to a motor through a pulley. The second thing is you must have take-up torque. If the tape moves but the take-up reel does not pull it onto the take-up reel then you either have a eaten tape or the deck will shut off. in your complaint it could be any of these items- maybe a bad Idler from the reel motor or the capstan belt is old and stretched.

Error 02 - 574


Main code 2X : Mechanism control system error
574 Failed to detect the T reel FG during search.

This means the take up reel stopped rotating during forward search. It shut down assuming tape was spooling loose into mechanism. Could be just a faulty cassette tape. A common problem is also when labels have been placed in the wrong places on the cassettes, stopping the lid from opening fully and stopping the reel reaching the reel motor drive.Manually eject the tape and try another tape. If the fault continues, have a look for something in the way under the cassette such as post it notes, paper clips, torn labels etc.
Have you had the unit serviced since you got it?
Could be time to get it to a service centre for help.

Cassette player problem


Sounds like the take-up reel isn't turning. Often the linkage for the take-up reel is used for both Play and Fast Forward. So test the Fast Forward.

I would look for a broken belt or slipping drive wheel. The fact that the tapes are unraveling tells me that the capstan is pulling the tape out of the feed reel.

Tape is stuck in VCR- Fast rewind and forward


It may need to be cleaned. Mechanical problems are one of the big problems with VCRs they use alot of mechanical moving parts and play for so long they fail. Plastic parts dont help much either. The pinch roller takes up the slack and is usualy the part that fails first because it constantly runs along the tape and builds a coating on the rubber so it doesnt grip the tape and pull it back into the cassette. If its not pulling the tape back in then it hangs up inside and you cant get the tape out. Fastforward uses the reels to pull the tape not so much the roller. Try and stop 2 times then fast forward then eject the tape. Try and eject the tape while its fastforwarding so it doesnt do anything else. Sometimes machines will unload after its been in fastforwad a while then it will eject. You will hear a change in the sound when it unloads, you can hear the mechanical arms move the tape in and out of the cassette. Thats when you eject it. You cant really clean it till you get the tape out. YOu can clean the pinch roller with fingernail polish or paint remover. It is a wheel inside it looks like a black tire. It pinches the tape against the capstan arm this is why it developes a film or a shine on the rubber making it slip.
