As the power button press the light will come on very clear I
can see the full screem with Olevia on the screen for just 1 second,
and then light goes off. Set has no functions, no volume, no sound.
I inject input from DVD player and from the salelite to the RF connector
and the video/audio inputs. there are no sound, no picture.
I attack my meter to the 24V line and monitor the voltage while the light
come on and goes of, at that point the voltage is not change, little change
goes higher to 25V on the right power supply board compare to the left one.
I try to unplug the LVDS cable from the T CON to the main board and there
is nothing change. I also tried to unplug the 24V line to the 2 invertors and all
slave invertors one by one, and still doing same. when I unplug the main inverter
and turn on I still see a small flash and goes of right away.
All the 22V . 4V, 5V, and 12V are stays no change as the light goes of.
