Bought a Hitachi 50ux52b/53k	Can't Post

Just picked up a 50ux52b/53k. plugged in power seems to turn on and the red power led on front comes on. looking in the back i see 7 different led's that come on, but i have no picture and no sound. if anyone can offer some assistance with this issue i would greatly appreciate it.

There are 8 led's in this set with one being red the other 7 tell you if a supply is being pulled down or other wise messed up. take the back off and wath them, If they all come on then one turns off in a few seconds that will narrow the problem down, now if one fails to light then you know where the problem is. Will try sending the LED chart to your E-mail
