Tascam 424 MKII - ate a tape and buttons dont' work. Heads seemed locked.
The machine powers up, and one little post spins round and round. It's the one on the right side. I don't know the correct name for it. It was working fine, and than it started going at double speed, and than it ate a tape. The tape got caught up in the wheel mechanism on the right.
The buttons are non responsive and the heads don't move at all.

Re: Tascam 424 MKII - ate a tape and buttons dont' work....
The machine has idler assemblies that provide drive to the "takeup reelbase" When this drive fails, the tape is not gathered up into the cassette, but rather wraps around on itself on the capstan spindle and pinch roller. The mechanism will not release until the tape has been extracted from about the capstan spindle. This can require all sorts of ingenuity to acheive with pout damaging or bending transport parts. The tape may not be recoverable. The deck will require an overhaul to the transport belt and idler drives to get it back to decent working order again. If you could get it to me, cost you about $75 to overhaul it If you are not in Brisbane Australia, then you may have to locate someone near to you.

I can honestly say I have been quite happy with it and its performed pretty well with very few problems and is still going today.
First of all congratulations on getting so many years of heavy use (2002 - 2012) on your JVC VCR.
I have a HR-S3911U and a HR-S5912U from the same era and my 3911 has seen a million miles and both my units are still going strong. I did experience a similar problem with my HR-S3911U but instead of the eject function my problem was with a sticking guide-pin. I did a have similar ejection problem with one of my 1985 Super Beta Hi Fi machines. Really it sounds like the exact problem as you describe. What I did was I opened up the unit and watched carefully - it was just a sticking moving part. My JVC guide-pin problem was just sticking as well - after a gentle push into place the guide pin has not stuck since. I don't suggest using any grease unless you really have to. I suggest you open the unit - if you have a video camera video tape the ejecting and play back in slow mo to see if you can catch the problem. Sounds like a sticking moving part which can be common on any VCR.
..couple times its had issues with dirty heads as i would get a message appear on screen.
I'm very surprised that in the past you had "dirty heads" messages pop up on screen as I have never seen that message on my JVC machines and I do use them a lot and very rarely clean the heads. Proper tape storage is very important. Trying not to use the same tape over and over again also helps keeping the tape path reasonably clean.
I think it could benefit from the heads being cleaned. I don't even really know what are the heads. Is it that big round drum? One thing I did notice is that when I load a tape, it straight away wraps the tape around that drum and the drum spins away and just idles there constantly rubbing on the tape before i have even pressed play. I have left tapes in there for days and days, so I assume this cant be good having that thing spinning away on the tape for such a long time?. I am not sure if this is normal or not but I wont be leaving tapes inserted in the VCR long periods now.
The heads are tiny little things inside the big round drum. I will show you if you post a picture of your unit with the cover off.
The tape staying wrapped around the drum with the drum spinning is normal but the drum should stop spinning five minutes after you load the tape as long as you don't touch play, rec ,ff or rewind. This is called a "long pause" (the tention is a little eased and is not rubbing hard as a normal pause would) and the long pause is there so the unit will immediately start playing or recording if you push play or rec within 5 minutes of loading the tape. If the drum does not stop after 5 minutes of sitting idle then your VCR has a malfunction and you should not leave tapes in the machine idling.
I am concerned about your heads clogging up - that is not normal unless you don't take proper care of your tapes - is there very high humidity in your area? That could cause problems.
Sorry I posted this in a hurry but will go into more detail later if need be.
When you use any cleaner or lubricant it must be only for the moving part and must never stray into the transport section. Also what is required if there is any frictio is to dry wipe and set. Now when you lubricant got sprread into the head, the oil will act as a great adhesive at higher speed and got the tape entagled. So please wipe dry all the oil of the headd and do nto damage the head with the wipe touching the delicate ferrite heads in the slot, DO NOT TOUCH THIS SECTION but with an even paper with soft brushes. Now check you reel drive and see if there is dirrt lodged in clean and reset., put the set on for regaining lost values as many electronics capacitors may have lost value by drying. If the tape up does not move it is a mechanical problem and you must check for the drive and the friction wheel. If however the reel works and the count does not happen and you get the error , then your reel sensor is faulty. Check these points and confirm, Hope this advice helps, Good day.
My mistake this is a 424 mkIII not a mkII. Sorry for the typo. Great news is I opened the power supply case and un-soldered the fuse. cleaned it off with tarn-x and behold 3 amps 250 volts. Definatly worth the $1.00 im gonna have to pay for that. As for the **** that was gonna charge me a $100 bucks. There is a reason you are doing that to people. And one day your services will be obsolete.
Error code 01:
what to do:
open the tray, power down the unit, remove the top cover, remove the transport (4 screws and a few conectors... I think there's a long 'transport load spring' also...) then turn the transport over.
Looking at the bottom of the transport, there's a small, -no, make that tiny- black rubber drive belt which goed from a very small pulley to a rather larger pulley directly next to it...
That's the one. Buy more than one replacement (they're only a buck or two) and put a new one on. -then take the spare, and place it in a baggie and tape the baggie up inside the lid of the DA-30MkII... Put some sort of friendly note in there for the next time the new owner of the machine needs to replace the belt.
Okay I have found two solutions here. They may both be the same but the information here is kind of vague so I will post them both.
I have found a PS-PS5 power supply as the title suggests. It can be found here: http://www.supermediastore.com/tascam-ps-ps5-power-supply-for-trainer-series.html
I have also found a power supply for the Tascam 424 mkii which can be found here: http://cgi.ebay.com/Tascam-PSP424-Replacement-Power-Supply_W0QQitemZ7405614833QQcmdZViewItem
Hope this helps!
there is a mechanical problem in your tape deck. probably a losen rubber band. it clicks because the rubber is too lose to move the mechinal parts. so when you power off, it losen the whole machanical parts..it is very easy to replace..opend the deck and check it out..good luck
