I acquired this TV from a friend and it worked great for about a year. Then the bulb died and I replaced it with a bulb from ExclusiveBulbs on Amazon for I think $25. This worked great for a week and then seemingly died just last week. I thought maybe this was just bad luck so I ordered a new one from the same store, and the bulb is working however, unlike before, now the screen has vertical lines that seem to show up against certain colors. See enclosed image and note the vertical lines, particularly visible thru the red Youtube, Smithsonian and Comedy Central logos. The lines show up on antenna and HDMI. Looks worse in person than on the picture. I thought maybe the bulb was not seated properly but removing and reinstalling did not help. Any ideas what the issue is here? The store on Amazon is telling me this is not a fault of the bulb.
