My TSR-24 effects box started to switch programs on it's own. Also the data
wheel only decreases the program number, regardless if it gets turned
clockwise or counterclockwise. I changed the internal battery, called the
system reset. If I stop using it for a while, it start bugging again. I
noticed that if I leave it on for a few hours it goes back to normal
operation.

Any hints?

Without really knowing, sounds like a logic chip or power supply...
perhaps even just a cold solder joint.

If it were me, I'd probably just start leaving it lit 24/7.... but if it's
actually a power supply issue, I might not be doing it any favors.

I was considering updating the firmware chipset but I'm not sure if the rest
of the hardware is ok. I'll probably replace it with an updated, used unit.

Open the unit, firmly press down on the dsp chip. Chances are, it has
become unseated, due to heat contraction and expansion. You'll feel it
click back into place in its socket. Power it up again, and see what
happens.

I had a Digitech vocalist that did similar stuff (except for the part
about getting better if I left it on -- it didn't). The problem with
mine was a dried-out capacitor in the power supply. Check that.

It may just be a faulty datawheel, or dry joints on the datawheel. Check
all the connections around it, or if you are up to it, change it. Often
these are off the shelf Alps parts at between 5 and 10 dollars or so.
Sometimes they are not and you have to get it from the manufacturer.



For the interested, the datawheel produces 2 squarewaves when turned, one of
which will lag the other depending on direction of travel One of these may
be missing, meaning it will only ever decrease the program number. The
other may be intermittent, fooling the microprocessor into thinking you have
turned the wheel.

Oops, a quick check to see if the datawheel alters data up and down properly
should tell you if the datawheel is the problem.

See the thread about MrMarksMusic. Disposable stuff. Sell it to Mark
and he'll sell it to someone like you who wants it for parts. g

I was working on a show with John V several years ago. The star was
just getting set up and his digital processor wasn't working. John
told him to look the other way, lifted it up and slammed it down on
the stage, and it came back to life.

Same thing, just not as expensive.

Now that I think of it, I seem to recall that it was a Digitech
processor.

I initially blamed the data wheel itself, but, what can make it work well by
just leaving it on for 4-6 hours? By the way, I just turned the unit on now
and it works fine after being off for 24 hours. But, I know it will do the
stupid one-way data wheel trick if I leave it off for more than a week.

I'll open it again to check the wheel and stomp on the dsp chip. Thanks for
the suggestions.

Stomp on all the big chips in chip carriers. The Data Pot will connect
directly to the processor chip not the DSP.

At least I'll rule out the loose chip posibility. It looks like some
soldering is needed if I have to replace the wheel...

This box is notorious for power supply connections going bad..
I have two of these boxes that I've salvaged with this problem.
One indication that the PS is related is if the display flickers
in brightness.. Another symptom is that the unit intermittently
resets.. I have to believe that there are more symptoms as well,
but in both the cases I've seen, the display was also flickering
in brightness...

BTW, as you know, These are nice sounding reverbs..

Thanks for the info. I use the unit exclusively to process an amplified
classical guitar. Boy, it surely sounds nice, but it's starting to show
it's age.

In what way? Face plate scratched? ;-)

It's still a pretty quiet processor with some nice presets and it's
packed with massively 'tweakable' parameters on all patches.
I've still got a couple of them... one I grabbed on e-Bay a couple
of years ago for $170, and they sold new for $1100+.

I gamble that after checking the solder joints on the jog-wheel,
reseating all chips, and doing any power-supply fixes that are
needed, you can get a lot more years out of the box.
