When you plug in TV, 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 one minute, then operate it again.
When you turn on by pressing the power button
on the remote control or the TV, it takes some
time to turn on the illumination LED and for the
remote control to be functional.
When the illumination LED is flashing in red,
count how many times it flashes (interval
time is three seconds).
If the illumination LED flashes red, reset the TV
by disconnecting the mains lead for two
minutes, then turn on the TV.
If the problem persists, contact your dealer or
Sony service centre with the number of times
the illumination LED flashes red (interval time is
three seconds). Disconnect the mains lead, and
inform your dealer or Sony service centre.
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
