Norm K, we knew of a guy who repaired my mother's 42" LG plasma TV for $230 recently, because he knew what part was known for failing on that brand, so ordered the suspect part and lo and behold it was a success.
We decided to take the punt as a new one of close to equivalent picture quality was going to far exceed that amount and we were very satisfied with that TV. 6 months later and it's running like a clock so far.
