The Sony KP-FWS57M90 television showing sound but no picture, followed by shutdown and flashing yellow and red indicator lights, is likely experiencing a failure in one of the deflection circuits. Based on the self-diagnostic system:
These issues can cause the picture to disappear while allowing audio to continue temporarily before the system shuts down to protect itself. The flashing sequence of the STANDBY/TIMER lamp can be used to confirm the specific fault. To stop the flashing, turn off the main power switch or unplug the TV.

The Sony KP-FWS57M90 television showing sound but no picture, followed by shutdown and flashing yellow and red indicator lights, is likely experiencing a failure in one of the deflection circuits. Based on the self-diagnostic system:
- 4 flashes indicate "Vertical deflection stopped"
- 6 flashes indicate "Horizontal deflection stopped"
These issues can cause the picture to disappear while allowing audio to continue temporarily before the system shuts down to protect itself. The flashing sequence of the STANDBY/TIMER lamp can be used to confirm the specific fault. To stop the flashing, turn off the main power switch or unplug the TV.
