I recently bought a 52" sony XBR (KP-53XBR4CT). The picture was fine at first but now when i first turn it on the picture will move up slightly and the move back down about every 10 seconds until the tv is warmed up. Also every once and awhile the picture will flip upside down for a second and then back to normal. Once the tv warms up it hardly ever does either of these two problems. Any one that could help PLEASE respond. Thanks
