Comet are replacing my tv under warranty. The picture has a number of vertical bands across the the full width of the screen, one particularly noticable. In adition, the slightest lateral on-screen movement causes the fleeting glimpse of horizontal back lines around the object that's moving. Not the halo effect btw, I see that too occasionally, but it rarely bothers me. I only noticed this new glitch at the weekend, after the Comet dude agreed to replace it. Is it realy getting worse? Will the new one be better. Someone reassure me I made the right choice.
