Ok last year right before the NFL regular season was to start our 720p 42 inch plasma HDTV stopped working. So we took it into Twin City, for it to be looked at. Apparently the motherboard needed replacing, and was going to be X-amount of dollars plus labour, but if we chose not to get it repaired it would be $50 fee for them to look at it. We paid to have it fixed, but that did not work and apparently another piece was needed and they contacted the manufacturer and it was taking a while. In the mean time we found a 1080p 40 inch LCD HDTV. And the new cost to fix our broken TV was going to be more then what we purchased it for and the new TV we just got. So we paid them the $50 for looking at it and we took it home, so I could open it up and see the insides of a HDTV plasma. Months past and I finally got to open it up and saw that a cable was not connected I connected it, turned it on and hooked it up to my laptop and it worked!
Maybe they replaced the motherboard and forgot to do that one connection and left the motherboard in? Maybe they were being shady?
Either way, that was my experience with Twin City/
