MCS2000 "FAIL 1/90" Hardware Problem or ...?

[Leadenwah]

I'm getting " FAIL 1/90 " on an MCS2000 Model 2.
Is this fail code ONLY a hardware problem or could a programming error provoke this message as well ?

In Bat Labs MCS2000 section, it is suggested that programming an MCS2000 with OLDER software that it was last programmed with will zap the radio.
So, would I also get " FAIL 1/90 " after someone had done that or would it be a different error?

Any suggestions or ideas are welcome.

Fail 01/90 on both the MCS2000 AND its portable brethren, means a hardware failure. Usually caused by a defective IC.

Thanks very much.

I've read in the Bat Labs section about a voltage regulator which is given to falling off inside of the radion not in the control head.

If you got this after you had programmed the radio,you can be 100% sure,that the codeplug is corrupted.

When I got the radio it had a broken control head clip which was replaced only to get " FAIL 1/90 ". So, it came that way, used. Seller says it works fine and has no codeplug is seems.

With other radios I've put in a newer version codeplug and it worked. The Bat Labs info suggests that the MCS2000 is more difficult in many regards.

The MCS could have been written with DOS-RSS or with CPS as I have tried to write to the radio without success. I am able to read the existing codeplug even though the radio otherwise unresponsive.

Any suggestions on how to get the corrupted codeplug out ? The newest vesion I have is CPS R02.02, but I'm sure there's something newer, however,
I don't think that it would have had the newest sofware used on it, all things considered.

Many thanks for this help.
