Question about Sony KP-57XBR10 57" Rear Projection Television
The screen on my sony projection tv is blinking. there is audio but the video cuts in and out. then on the screen the display comes on. the LED light blinks 5 times. so it as to do with an akb circuit or some other circuit on the video board. but i dont know what to do to fix this problem.
If the video cuts in and out, chances are the Screen trimpots are not centered correctly in their proper range, relative to each other.
Sony does a balancing act whenever the set is turned on - there is a white line at the bottom of each CRT, and the current drawn on each gun must match the others, at least within a given range. If one is too high or too low or in any way vastly different from the others, the set will not allow images to hit the screen, they will stay blanked indefinitely, until the Screen trimpots are rebalanced correctly.
