Troubleshooting In order to keep your TV software up-todate, it is necessary to download the latest software information via the digital broadcasting system or internet and to update the software. Select [Update Now] to start a software update. The illumination LED flashes white while the software is updating. Do not unplug the AC power cord during the software update. If you do, the software update may not finish completely, and it may cause a software malfunction. Software updates can take up to 30 minutes. If you do not wish to update the software automatically, press HOME and select [Help] [System software update] [Automatic software download] [Off]. When you unplug the TV and plug it in again, the TV may not be able to turn on for a while even if you press the power button on the remote control or the TV because it takes time to initialize the system. Wait for about 10 to 20 seconds, then operate it again. When the illumination LED is flashing red, count how many times it flashes (interval time is three seconds). If the illumination LED flashes red, reset the TV by disconnecting the AC power cord from the TV for two minutes, then turn on the TV. If the problem persists, contact Sony Customer Support (information provided on the front cover) with the number of times the illumination LED flashes red (interval time is three seconds). Disconnect the AC power cord, and contact Sony Customer Support. When the illumination LED is not flashing, check the items as follows. You can also refer to [Troubleshooting] in the Help Guide or perform self-diagnosis by selecting [Help] [Self diagnostics]. If the problem persists, contact Sony Customer Support (information provided on the front cover). Troubles and Solutions There is no picture (screen is dark) and no sound.
