Sony KP-53XBR200 blinking red 5x, screen blanking for a couple seconds

 

It all started with blinking 5x red light for a couple weeks with no real change in the picture, maybe not as sharp as usual, still watchable.  Cutting the power to the tv worked at first to stop the blinking, then that failed to work, the light remained. Tried the flash focus which would take longer than usual and errors would appear at the end. Like, E 14G, E 16G, E 17G. Then the screen started cutting for a couple of seconds and then return for 5 or 10 minutes then shut off again for a couple seconds then return. Now the tv is working with decent picture, flash focus is working properly, no errors. But,the 5x blinking light remains. I went into service mode to check what errors have occured and the AKB has occured 82 x

Any suggestions.  Also, does anyone have the service manuel download.
