Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

you can have the inverter board replaced...instead of the entire panel.
KDL 40S2010: inverter part # 178950032, you will also need 2 spacers..part # 289765511
you're looking @ 200-300$ for the inverter and 5-10$ a piece for the spacers.

KDL-46V2500: inverter part # A1251295B
you're looking @ around 500-600 $ for the part

SOURCE: standby light flashes 3 times

A 3 flash pattern indicates that either the lamp is not seated correctly or that the lamp door is not latched properly. It can also be a fault with the switches that sense whether the lamp is seated or the door is latched. Try reseating the lamp and relatching the lamp door
