hi -
my TC Finalizer has been in a rack in my studio and not powered up for
over a year.
worked fine last i used it.
just pressed the power switch and it's got a solid red light behind it
and nothing else happens.
unit wont "power up".
yes, the rear main power switch is on.

any ideas?

thanks -

Dez

But there is no display backlight? Get out the meter and start looking
at power supply voltages.

thanks Scott.
i would surely do that, but i am at someone elses studio and did not
bring the voltage meter.

thanks again-

A studio without a voltage meter?

Well without that voltage meter this is hard to fix.

Get one (neighbor?), open the finalizer, check the output of the supply
voltages according to Scott and:

1. if you have no output voltages
-- check fuses
-- if it is a switching power supply you have almost no chance, you could
check the PWM signal out of the timer LM555 or what ever.
-- if it is a linear one, check the AC output of the transformer, check
the voltage regulator 7805,7812,7815 or 7905,7912,7015 right pin is output,
left pin is input, middle is ground.
-- check rectifier
-- check is the mainboard of the finalizer has a shortcut
-- Try to get one or more power supply to supply the mainboard

2. if you have ouput voltages
-- check if they are in the range, if too low, check for shortcut
-- Try to reset the device by hardware (short uP or short EPROMS for a
short time)
-- shake to device (sorry for this)
-- check for bad solder points nearby the powersupply

Hope this helps,

Lukas

Buck-fiddy sez it's a cap in the power supply.

I base this on nothing other than every time I've left a piece of gear
sitting for a long time then had it fail on power up, the problem has
been a bad cap in the power supply.

Well, at least you have enough of the power supply working to light the
red light. That's a good sign. How much do you know about electronic
troubleshooting? If you don't know enough to check power supply
voltages, you'd best leave it for a qualified repair shop.

I don't know what it is about people that makes them think that they
can fix a complicated electronic device if they don't have any test
equipment, documentation, basic electronic knowledge, or wouldn't know
what they were looking at if they got the case open. I know someone is
going to think this is condescending, but it it doesn't work, it's
broken. Get it fixed,dammit, or put it back on the shelf. I know how it
makes you feel to pay $75 to have someone replace a fifty cent fuse,
but knowing where the fuse is costs $74.50.

(or sell it on eBay, saying in the description "It doesn't power up but
I've been told that this is just a simple problem." )
