I think it's time to search the net for a schematic and a service
manual.

The flashing light combination probably represents a special
diagnostic code referenced in the manuals, which will save
you a great deal of time and frustration.

You can probably also get the meaning of the codes from
tech support.

Finally, electronic knowledge without manuals will not
help you that much (I am an ex-electronic tech, now
computer engineer too), because the entire TV is controlled
by software.

There are tons of secret codes and key sequences
(from the remote) which factory repair technicians can
use to diagnose or tweak the machine, including
color balance, video and format parameters, reseting
usage timers, clearing error codes ... etc.

There may also be an USB port for diagnosing the TV
via a computer with custom software.

I am afraid that without a service manual, basic voltage
and continuity checks are the limits of your investigation.

Martin.

replace the lamp on your TV, but only replace it with PHILLIPS brand. Anything other than that, will not last. We just replaced ours with Phillips and the picture is much brighter. It really shows the HD quality of the tv.

solid green - power on

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.

NO PICTURE OR SOUND


Hi
Usually, if the red light is flashing and you get no picture, that means that the lamp life cycle is finished and you'll have to get a replacment lamp. the lamp has about 3000 hours of life (2 to 3 years under nomal use).

You can buy a replacment lamp from here

All you need is a new lamp thats what the 3 lights blinking is indicating. Very easy to do this yourself. Just order a new lamp and let me know when it arrives and I will explain how to change it. Very easy takes about 5 minutes.
