I have one of the stated TVs. It powers on fine, but has no viewable picture. Sound is there and if you shine a light on the screen you can see the video content. Thus there is a problem with the back light. I am assuming this could be because of the power to the backlight or because the light itself is the problem.
Below are the readings from the power supply:
Pin Label TV Off TV On Pin Label TV Off TV On
1 On/Off 69 mV 69 mV 9 Dim 3.3 V 3.3 V
2 NC 0 0 10 PS_On 3.3 V 3.3 V
3 Grd (-4.5 mV) (-4.5 mV) 11 Grd (-.8 mV) (-.44 mV)
4 Grd (-4.6 mV) (-4.6 mV) 12 Grd (-.8 mV) (-.844mV)
5 12V 12 V 12 V 13 12V 12 V 12 V
6 12V 12 V 12 V 14 12V 12 V 12 V
7 12V 12 V 12 V 15 12V 12 V 12 V
8 5V 0 0 16 5V 0 0
I don't understand the readings as I would expect different readings with power off (i.e., plugged in, but switch off) vs. power on (switched on). Though from above there is no 5V reading. Does this seem to make sense to anyone?
