Question about Mitsubishi WD-57733 57" HDTV
Both problems can be caused by a failing solder joint in the main power supply; you may not need a bulb yet. <div><br /></div> <div>The supply may be on a separate board, fairly easy to remove. If you or a friend has a <i>quality</i> soldering iron or station, you might unplug the power supply board and visually inspect (with magnification) and look for a solder joint that looks rough or is cracked (it happens), use fresh resin core solder and reflow any suspicious soler points. </div> <div><br /></div> <div>If you are concerned about getting the supply reconnected, take a couple of snapshots of the wiring to and from it before disconnecting.</div> <div>The plugs are normally all different so tough to interchange by accident.</div>
