transplanted QSI decoder issue

Maybe someone here can shed some light on this one.

I have a Atlas/Kato C425 that I stuffed the electronics from a BLI RSD-15 into and plopped a new shell on top. It was working fine for months until the other day.

Now when I try to use the horn (every now and then it works as it should) or the smph readback it dies on the spot, and it very rarely (like 1 in about 20 times)  dies when switching directions. Other than that it runs great.

I consulted a friend who is pretty versed with QSI, and we tried a version 7 chip in it andreseting it with decoderpro and QSI's programmer. Still the same results.

I haven't tried the hard reset with the magnetic wand yet, but I'm suspecting the board is shot. I'm planning to call BLI and QSI tomorrow. But I don't think it will end to well for my wallet (I mean I have only $75 in this loco, $10 for the drive, $15 for the shell, $50 for the decoder.)

Does anyone have any advice for this one?

Worse case scenario is I'd have to buy another board for it. If that happens I'll probably just stick a motor decoder in it and MU it to my Bowser C636 whenever it shows up.

If N scale had good SD40-2s, C30-7s, U30Cs, SD45s, SD40s, and SW10s; I'd be in N scale.

Didn you try reset to factory setting s with CV49=128, CV50=255, CV56+113? If you do a hard reset, you need to power down (or take the engine off the track) before the reset takes place.

Sorry about the delay. I tried the reset with CVs, but I didn't know you had to cut the power for the hard reset to take effect.I'll try it later.
