I don't know how attached you are to your old PS3, but it would probably be easier to just buy a new one for $200. Or pay for a refurb unit from SCE for under $200.
About the only reason to repair a PS3 (and I've done about a dozen reflow/repair jobs) is to get whatever data you can off it before it dies again. You won't be able to keep your game installs, but you can at least get your saves and whatever non-protected videos and photos you were keeping on the HDD.
