Don't know if there are any engineers/techies who have a clue about this issue. Basically I have a JVC AV32T25S, bought in dec 03. I got an engineer out because of some colour purity issues. I was unable to be at home when he came round but I spoke to him on the phone when he was dealing with the TV. He did notice the purity issues and manually degaussed the set - this seemed to have slightly cleared the purity problems ( but they are still there) - he said that left as it was the set would be deemed to be within manufacturers tollerance. I got home and there did seem to be an improvement. Anyway perhaps a week or so later while watching NTL digital a kind of bright light zoomed across the screen like a shooting star - very small probably a mm wide from left to right. This happens ocassionally - no specific pattern to when it occurs. I haven't noticed it on DVD's. I wonder if this is anything to do with the scanning lines? Could this have been caused by the manual degaussing? because I definately did not notice this before the engineer came. My girlfried said that that was all the engineer did ( manually degauss then left). Oh and she does'nt notice the "shooting star" thing when it happens (typical) I do not recall seeing this issue anywhere on these forums. Any suggestions?
