TV turns on, Sony logo appears, then screen goes black. Sound continues via optical out.
Many modern TV brands (such as Sony, Samsung, and Panasonic) use the standby LED as a diagnostic tool.

Always consult the specific manufacturer service manual to decode these blink patterns before tearing down the chassis. Advanced Screen Bypassing Techniques
Check for the standby voltage (usually 3.3V or 5V). Force the power supply on by jumping the Power-On (PS-ON) pin to the standby pin using a 1k-ohm resistor. Verify if the secondary rails (12V, 24V) stabilize. Phase 2: T-Con Board Analysis
