I replaced a damaged power supply board in an old starview box that hadn't been workin for more than a year. The box turns on fine and is displaying the channel data along the bottom of the screen with no picture or audio but then the msg. NO SIGNAL appears. My signal is fine as my current Starview 2 works fine. the firmware currently on it is v2.57. I would really appreciate any tips as i'd laike to get this box going so that a mate can get some use out of it before all the channels get moved upto N3.
