Hi everyone..
I recently got a Sharp Aquos LC20E1-S LCD TV. The problem is it didn't come with a power brick. The unit runs on 13VDC and uses 54W.. I managed to find a picture of the power brick for this TV and it has 3 seperate 13V connections to the board inside. I have checked the board with an ohm meter and they are completely seperated inside. One power wire goes to the audio amp, one to the tuner / lcd control board and one to the backlight inverter. I'm not really sure for the reason of seperating them, but I assume that it is for interference reasons and that the TV should power up if given 13V to all of those points even if from the same source. Anyhow I have tried powering it by tying all of the 13V+ togeather and giving them 13V and I get nothing except for a small noise from the speakers and a light very briefly turns on. Just enough to see it. Does anyone have any expirenence with this TV? I have a friend with the same tv.. Maybe I can borrow their AC adapter and try it on this one. Here is a pic of the same TV and the strange DC jack.
