922's how many are still running?

With the Dish and NBC feud, I decided to look to different options. I saw a 922 on Ebay for decent price so I bought it. I bought it thinking that it had a dual OTA module already installed. After receiving it, I realized different.
No problem, I will just buy one for 30 bucks and fix my wife's Dancing with Stars and AGT problem. Well, the 922 failed to boot, the dreaded Starting up... screen.
Long story short, I ended up with two 922's, one from ebay and the other from Dish, to replace the ebay one. Neither one will fire up. Dish said recycle it and the ebay seller refunded with no return.
I now had to open them up and look for a problem. I found some Caps that let go.
To my question. Do replace the Caps (which I have done before with TV's) and try and repair the 922 or just keep using my 722 and 722k?

Thanks, Brent
