Lexicon 224 v4.4 Startup Error Codes

[dbbubba]

Does anyone here have a list or know what the startup error codes mean o a Lexicon 224 v4.4?
Don't tell me to call Jim Fabiano.

I am getting E92 at powerup.
The unit comes up in a strange mode with too many LEDs lit on the LARC.
After you hit a few buttons it appears to function normally except the "ovfl" LED stays lit.
The readout seeems to be pulsing a bit more than normal.

The Ni-Cad batteries on the OPT (option) board are dead as a doornail.
This only stores programs you have created and the unit should work w/o them powering up.

I have cleaned and seated most of the socket mounted ICs.
I have cleaned all of the edge connectors.

I have another functioning unit, but it is a v4.3.
I am going to start swapping cards.
I also have a another completely non-fuctional v4.3 that needs a whole new CPU board.

Anyone have the error codes handy?

Nevermind.... I figured it out.
Bad DMEM card (dynamic memory.)
I have a spare.

Do you want to sell the dead 224 with the no go computer pcb? I have a spare here.

Hi !

I was mixing a track yesterday, using my 224... stil love this unit !

But since yesterday night => E92 at startup , with a BIG BIG noise.
So, E92 seems to be "bad DMEM card". ok great but what am i gonna do ?

My unit has been serviced by Jim fabiano in february. I live in france and i cannot send it to him again (Shipping charges to high !)


Could a qualified electronic technician do a good job on the 224 ?
I see there are many "chips" on that DMEM cards. Mabey a dead one ? Can it be easily changed ?

Thanx

Usually it's corrosion on the socket pins. Lift them out and re-set them, it should come back to life.
