I have a x27sv-naga lll LCD TV that I use at work. It was working fine till one day it started to get snowy on the cable input only. The vga/dvi was ok at this time. I sent it back and they said they couldn't find anything. I put it back on the bench at work and started to use it and found that the pic quality went away but no snow. This went on for a few months then the snow came back on all inputs, it woud come and go when it wanted. The unit was warmed up and cold it didn't matter when it happen to come back. Help, it was under warranty now it isn't.
