IS this a common problem? In a CRT, I would swear they were a magnetic field spot, caused by the surround speakers.I do have 2 1 foot LED light strips attached to the top lip, of the back side of the cabinet. But stars spots are at upper left, and tw

o at the bottom right, lower third. I have replaced the Main bulb after 3.5 years of having a true quality 1080i HD picture, but shortly before, and continuing after the Bulb change, I started with a yellow/greenish star spot at the top left third of the screen...Im pretty certain my surround speakers are not close enough to be the cause...theyre a foot and half back and same distance away from the corner. Now have Purple one in Lower right third, and this week a red one popped up close to it!
