Does anybody have a Lexicon 224XL manual online that I can reference. I
can't seem to be able to store any patches on mine.
Thanks,Alex

I have the same problem. It boots without diagnostic failure but fails to store
new patches. The old ones are intact and can be modified but not stored. I
checked the backup batteries and they're fine. I'm guessing it's a logic
problem. Given the age and all, I've just decided to live with it as is.

We never had a service manual.

I have the same problem, I wonder if a hard reset would do the trick?

Hey again... we have a 224 quad at Artisan and can only store 4 patches.

I would be careful about a hard reset, which I haven't really heard of....
there is a software/firmware upgrade for "mode enhancement" and
"decay optimization" (lights 7 and 8) on earlier units. You might lose
these but I am really not sure.

The only thing that comes to mind is the internal surface mounted
battery. These things really need to be replaced fairly often. We
replaced the battery in ours about a year ago and did not lose those
firmware upgrades.

It's amazing how Lexicon can brag about having pioneered digital reverb
while simultaneously denying the existence of any legacy products.

Replace the batteries in your 224XL, you'll be glad you did.

I gave up after many attempts by phone and e-mail.

We leave our unit running 24/7 and the batteries are still good! (1983 is the
date on the circuit boards...)

I really dislike Lexicon's lack of legacy product support. Sure it's hard to
find some of the parts, but a little help would be nice. The 224X is still a
great-sounding reverb but I guess we're going to have to find a replacement
pretty soon.

Show some patience. Jim's been ill and unable to respond. He's the man
that can solve your 224 problems. He's worth waiting for and the 224 is
worth keeping.

I didn't know he was ill, but I've been trying to contact him for over two
years... I think that qualifies as patience.

Hi,

The 224XL has 3 tagged Nicads soldered to the uppermost CPU board. They
have a limited life like all Nicads and often leak. You will need to
replace these and, if the leaking has damaged the PCB tracks, you may need
to repair them. Sometimes this is why just replacing them doesn't work.
Also there is a 270 ohm resistor from the +ve terminal to the backup rail
that you should check. You should be able to measure the Nicad voltage
(about 3.5 volts) on pin 18 of U12. If this is present but the memory still
fails on powerdown, change this memory chip. (It's a 6514 or 2114 RAM chip).
If you replace this, it MUST be a CMOS version of the device, otherwise the
current drain will empty the batteries in less than a day. Good luck trying
to find one.

It's easy to pop the boards out - take a look and all will be rather
obvious.

Gareth.

This with the board removed from the unit.
