I believe I had a brief power surge and screen shows an "8", and is completely frozen. I tried the unplugging reset procedure twice, and the "8" continues to appear. Is the unit fried, or is there ano

A number of scenarios may yield a frozen fire stick. And just what screen is visible during the freeze is sometimes relevant. Other than a reset procedure, you can also consider the scenarios mentioned on the following page:

The standby light on a Sony television indicates when the television is turned on and operating, or turned off and in "standby" mode. However, this light also serves a secondary function: indicating when there is a problem with the television by flashing. When the standby light begins to flash, there are two reset options that can be performed to resolve whatever issue it's indicating -- a power reset and a factory reset

POWER RESET
1. Turn off your TV

2. Unplug the television from the electrical outlet. If you're using a surge protector or power strip, disconnect the television from the strip itself. Only by disconnecting the power cord from the outlet can you ensure no power reaches the TV during the power cycle.

3. Leave the television without power for at least 60 seconds. This gives the television enough time for all components to power down during the power cycle

4. Plug the television back into the electrical outlet. If you're using a surge protector or power strip, plug the television directly into the wall outlet instead. The surge protector may otherwise interfere with the power-up cycle, especially if it is old or damaged.

5. Turn on the television. If the blinking standby light continues, you'll need to move on to the factory reset process.

FACTORY RESET

1. Turn on the television.

2. Press and hold either the "Reset" or up arrow button on the remote control.

3. Press and release the "Power" button on the front of the television, while keeping the "Reset" or up arrow button on the remote depressed.
4. Release the "Reset" or up arrow button.
5. Allow the television to reset after the "Reset" message appears on the screen.
6. Make no adjustments to the television for at least one minute after the reset has completed. This is to allow the television time to finish auto-configuration and initial set up.
7.Turn off the television and unplug the power cord from the electrical outlet.
8. Wait ten seconds, then plug the television back into the electrical outlet and turn on the TV.
9. Follow all on-screen instructions to complete setup. These are the instructions displayed the first time you set up the television, for configuring channels, menu language, time, display properties and more.

Re: tv kdl-55ex620 red light blink 8 times Do a Power Reset. 1. While the TV is off, unplug the power cord of the TV from the electrical outlet. 2. Let the TV remain without power for 60 seconds. 3. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.) 4. Turn on the TV. 5. When the TV powers on and a picture is displayed, reset the TV to factory default settings.

• If the Reset message does not appear and the TV turns off and on, begin again from step 5.

• If the standby light begins blinking eight times, return to step 1.

6. After the Reset message appears, allow the TV to reset. Do not press any buttons on the remote control or on the TV and do not make any other adjustments for 1 minute. 7. Unplug the power cord from the electrical outlet. 8. Allow the TV to remain without power for 10 seconds. 9. Plug the power cord back into the electrical outlet. 10. Turn on the TV.

• The initial setup screen displays if the above procedures were performed correctly.

11. Follow the on-screen instructions to complete the initial set up. 12. Perform a system software (firmware) update.
