We stupidly decided to buy a little-known ITa HD TV through Ebay at a very competitive price - about $400. That was our first mistake.
After setting it up, we followed the instruction pamphlet (no, it didn't have a screen guide) and were unable to tune in three HD stations.
We tried repeatedly without success before deciding to pay for a qualified TV technician. After two hours he, too, was flummoxed.
Analog was okay but not those missing HD stations!
We also found out - much to our disdain - that the built-in DVD did not work.
After much correspondence with ITaconnect, the problem was not resolved. Quite simply, they kept coming up with specious excuses and, in essence, blamed us for not being adept at installing the TV.
This despite many attempts and enlisting the services of a techie!
Over a period of three weeks, we explained time and again what the faults were and each time they deflected the blame. We complayed to the Ebay administrators and, despite conceding others had had similar complaints, they essentially sided with the sellers.
At the time of writing, we sent the TV back after Itaconnect said they would get their own techie to inspect it at OUR expense!
We've written this off as a lesson learnt: don't buy unknown or inferior brands of TVs - and certainly don't by them over the internet...
