There's a CT Limit Digital Electronic Service Center upstairs in Ever Mall. I've never used them, so can't recommend them. It's just the only place in town that I know of. Took my videocamera there, but the P3500 quote was more than I wanted to spend. Just going to wait til I go back to the states, since it's still under warranty.
I took my Sony to the Sony repair shop in Dgte about a year ago. It took FOREVER to get it back (which is typical), then it stopped working again so they sent it to Hdqtrs in Manila. It worked for awhile, but has since stopped working again. By the way I have a 6 month old Sony CX 550 camcorder for sale if you end up needing another one. It's P76T in Phils. My wife has it in Cebu, but she's about due to head for southern Negros for a family visit any day now.
