Q: Hitachi VCR VT-3012A False Tape Indication

W

I have a Hitachi VCR model VT-3012A that intermitantly indicates the
tape is loaded when there is no tape in the machine. This happens simply
by cycling the power on and off. Once the indicator comes on, it will
remain on until I unlatch the tape carrier and force it through a cycle
or keep turning the power off/on until the tape-in indicator goes out.

Other times, I can turn the power off/on several times w/o a tape and
the VCR is okay. Then, the next time the power is turned on, the tape-in
indicator may come on. The load mechanism drive belt was stretched
loose, allowing the belt to slip when the motor does a brief spin as the
VCR powers up, so I replaced it. Made no difference. If a tape is
loaded,
the VCR works normal.

I welcome any suggestions as to what is causing the tape-in indicator to
turn on without a tape in the loader. Thanks in advance for your
assistance.

A common fault on older Hitachi VCRs is that the end sensors fail

intermittently causing odd symptoms, possibly including this one. If the end
sensor lamp is a bulb rather than an LED, replace that too.

That chassis has a lot of problems with the mode switch getting dirty &
causing those symptoms. Pick up a can of tuner cleaner in a spray can, with
a nozzle. The mode switch is located just to the left of the loading motor
on the upper right corner of the chassis. The easiest way I have found to
clean the switch is to take a sharp object (I use a dental pick) & pry the
edge of the switch to where you can spray into the switch. (Have the power
cord unplugged for this) You need to flood the switch as it's pretty hard to
get to all the contacts inside the switch. Plug it back in & load a tape,
cycle it through all the functions, play, ffwd, rew, etc. Hopefully this
will fix the problem
 
Or load switches or, more likely, supply or takeup phototransistors. Used to
be a common problem.
