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.
Have you tried any of the reset commands?
Try these....please let me know the result:
1. Unit power must be ON and unit must be in STOP mode.
2. Press and hold [CH UP] and [CH DOWN] ON THE UNIT for over five seconds. The unit will turn off.
3. Press [DVD POWER] to turn the unit on.
1. Press [STOP, TUNE MODE] on the main unit and [>10] on the remote control at the same time for about 3 seconds until the message "Initialized" disappears from the television screen.
2. Turn the unit off and on again.
While the unit is off, press and hold [VOLUME +], [OPEN/CLOSE] and [POWER] on the main unit at the same time for more than 5 seconds.
While the main unit is on, press [POWER] on the main unit for more than 4 sec. (All the indicators will blink twice when the main unit is reset.)
Another possibility is to unplug the power cord......wait 30 minutes and plug it back in, possibly repeating the steps above. (Method 1 should reset the unit but maybe trying each of them may be necessary until it is reset.
The message appears to be one that displays when the unit is in a setup mode.
Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. https://homenol.blogspot.com/ https://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.

How many times does it blink. It should be blinking a repeating code if its in protective shutdown mode. A continuos blinking with no pauses means.
