Batboard

i have a mtx8000 that i got and when you turn it on it showes FAIL 8E/92, i cant read or write to the radio does anyone know what this is and if it can be fixed

thanks

I can't find a "FAIL 8E/92" fail code for any JEDI.

Are you sure it isn't FAIL 01/92 or 01/82?

FAIL 01/92 or F01/92 = FATAL > Internal EEPROM checksum error Bad internal codeplug data,
Defective microcontroller

FAIL 01/82 or F01/82 = FATAL > External EEPROM checksum error Bad external codeplug data,
Defective external EEPROM

Anything can be fixed, if it's valueable enough to you...

no for sure its 8e/92 i cant find any info on it either its wierd,
and yes i would definately like to get it going, must be a way
i thought the same thing 01/92 but i don't know

for sure thats the code, i thought the same thing cause i cant find anything either for 8E/92 , wierd......
i would really like to get this going

I have the service manual for the things. I'll give it a little closer look and if I can find anything to do with 8E/92 I'll let you know here.

I'll save you the trouble. Just checked the service manual, and that code doesn't come up. Strange........

wierd we'll what if the code was 01/92 how can we fix this, do we know what the 1st 2 digits mean?

Well, if you mean what do the 01/XX mean, the 01/ just means the error or failure was detected during power-up test mode.

Operational display codes are formatted different, for example; FAIL 002 (or F002 on top displays).

About all you can reasonably do is replace the control board. It's not a difficult task if you can find one.

If it's an 01/92 it's a bit more serious than a 01/82 error. However I'd suggest reflowing the pins on the EEPROM and give the uP a quick reflow with a liberal amount of flux to assist in the job. (need to have a hot air gun unless someone else has a better idea). If that doesn't work, well what do you have to lose labtool it and see if you can bring it back to life. If that don't work, you'll need a new controller.
