Have you tried resting it by unpluging? There is a blink code though I'm not sure what it is for these units. Id check Sony website.
* Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.
This seems old but could still be accurate
