first of all where are you located and how much you're willing to spend?
most of such shops will charge you upto $150 of labor + parts.
i can be in help fixing for you these units for $100 each of labor + parts, but i'm not sure if you will spend such money for the old unit + round trip actual shipping(i do the fixing as a home technician and as hobby as well)
i checked ebay on your items and i believe that it's not worth to spend money and/or send it for the repair rather than hunt a little-bit on these units on e-net since they're in the range of $150 in average.
