Not recording? Wont let me retrieve anything. Says end of tape with a blank screen.

take the lense cap off

Probably the pins in the video head are broken. you have to change the video head.

You may think the tape has an hour of material on it, but the machine thinks otherwise. Either it didn't actually get recorded past the 11 minute point, or something erased the tape past that point. There's nothing to play after that time, so you're seeing the snowy screen. On most VCRs, the tape counter only works when a valid video signal is detected, which is why it's not advancing as the tape plays. There's nothing you can do to recover whatever was on the tape, so I hope it wasn't anything important.

Several things.
Check the tape, by opening the cover, to see if the tape is damaged. Look for signs of crinkling at the edges. This is often caused by the roller being worn on one of the VCR.
If it's damaged there's not a lot you can do.
If there's no damage try taking it out of the cassette box and fitting it in a new 'good make' blank tape tape box, discard the new tape in it. Still no good?
Next step, is the tape a movie/tv made by a commercial company. Or a recording on a blank tape?
Did it ever play? (if a movie) if not suspect a pirate tape report seller to FACT.
If a blank tape, try recording on a blank section. If that doesn't work and your video will record on other blank tapes. The tape has something wrong with it.
Some video recorders will play tapes with bad problems IE bad tracking, that others refuse to play, but you will either have to find one owned by a friend or buy one with that claim.

Pull the battery out and let it sit for 2 minutes,reinstall the battery,if that doesnt work save your recordings,and then format the recorder.If still no success,send it in to olympus for service

WHAT "" system needs to be calibrated and then configured ""........""It works fine otherwise""
Disconnect the VCR from anything. place a vhs tape with information [picture of something you don't want any more or a vhs tape that you want erased] in the machine. The tape at the back left TAB must be covered to promit recording. turn machine on,shub the tape in, press record. if after a time and you REWIND, and the begining is blanked of picture information...........the recorder [VHS] is working. looking to see the cables and how they are connected.

Use different tape. Is the tape still attached to the feed spool, or has it become separated ?

Have you tried playing the tape in a regular vcr with the VHS-C adaptor?

If it plays back pre recorded tapes then there is nothing wrong with that section of the unit. Does it playback audio and not picture or does it not playback anything.
Also, when trying to playback a recording what is seen of the screen? Snow(black and white dots or wiggly picture?

The unit uses two separate circuits to record and playback tapes. Is any thing else connected to the unit while you are recording? If you are using anything plugged into other ports on the recorder it may not see the camera input causing it to not record anything..

check to see if iris is opening and closing, could be seized vanes on iris motor. Good luck
