Faulty mode switch or no take up rotation, does it give an error code or does it still do it if you instantly put into pause? John.

probably the gears on the dynamic drum head tilt assy that has split. you usually get a knocking noise as the worm tries to turn it. not available seperately however....

It gives no error code, mode switch, well i gues is allright, take up rotation is also allright, i cant go in pause mode, just switches off.

Well, i think thats the prob, but no splitted gears, a slipping worm, however how can allign this assy??

Herm.

Theres no explanation in the manuals on how to time these gears.!!! As I said before you can't buy them... only a complete head assembly which here

You can usually remove the motor/worm/pcb safely to check without upsetting the timing, however its not these gears that usually split, its the 2 drive gears up into the head assembly with metal shafts.

as to timing these 2 / 4 gears I've no info on that ! just pot luck really, since its a dynamic system as long as theres enough movement end-end it should be ok, since its the head 'envelope' that the electronics look at to check correct alignment.

Upon initial power on, the micro moves the motor/worm/blades back/forward to check that theres movement. only if this is ok will the unit come out of standby. Then if you need any other mode than play, ie shuttle /pause the motor moves again, counting pulses on th e photo interrupter. Since pause/slow-mo is a different movement to shuttle , whichever damaged gear jams, that will then cause an error to be detected - and shut down or stop occurs.

I have a customers machine (9500) sat here, which I need to arrange to somehow bypass these broken gears with.. (Thinking aloud...)Perhaps if the motor is allowed to spin whilst disconnected from the gears.....it would not detect an error..... still picture and shuttle picture wouldn't be perfect but at least record/play would work....

hope that helps

Andrew

you

The simplest method to time these is to (with power plug pulled) remove the basket, then turn the loading mechanism by hand until the load arms would just stop retracting the tape. This is the STOP position. Then align all the gears so that the basket can be mounted in the down position. When the machine is then powered up it should reset itself to the tape eject position. This method should work in

99% of all machines.

Thanks Andrew,thanks a lot, however, i messed up the alligment real bad :(( and it's very difficult to get them right, i have a picture allright but nog optimal. Thanks.

This would discribe the threading alligment?? Correct me if i am wrong.

Herm, alignment is relative to each vcr model. Some are simpler to reset the gears than others. Most have some sort of cam which controls the tape loading arms but which also relates to the basket gears. What often happens is the relationship between the tape load arms and basket position is accidentally upset for various reasons, i.e. jammed tape, forced loading or removal, broken parts, etc, resulting in slipped of skipped gears.
