Well I just learned something new... I've not actually owned a Matrix 1000 but have had several Matrix 6 and 6Rs that I've bought will issues, made repairs, and have since sold them all. I only buy them if I can get them cheap and that usually means broken, and haven't come across any Matrix 1000s that fall into that category. I'd seen the narrower CEM 3396 in the listings, now I know where they're applicable...!

My best answer for the failure would be that something else upstream in the circuitry is wearing out possibly causing stress and eventual failure on them. ...just a guess without a whole lot of basis at this point. The CEM 3396 is still a pretty cheap IC to replace and available from a few Ebay sellers for as cheap as $5 or $6 a piece, not much compared to a CEM 3310, 3320 or 3360, etc. that can go from as low as $40 to $50 on up.
