No display, "No Signal" on TV, or a fuzzy/green screen. The Fix: The HDMI Retimer IC (located near the HDMI port) fails, or the solder pads under the HDMI port get ripped off. BoardView Utility: The BoardView file shows you the exact pinout of the Retimer IC (U29 on most revisions). You can identify the 19-pin HDMI connector, trace the differential pairs to the Retimer, and then trace the secondary pairs to the Southbridge (U1). If a pad is ripped, BoardView tells you which via to jumper wire to.
