My house took a direct lightening strike on 7/31. My Hitachi 53FDX01B digital projection set will turn on but no audio or video. The power LED on the front stays on when set is on (no flashing). The power supply board fuse is good and all of the LEDs on the power board (D903,D912,D927,D931,D949) are lit when the set is powered on. DP29 and DP37 on main board are not lit and there is no high voltage. No visual indications of any burned components or arcing. If the power supplies are OK, where do I need to look next? I no longer have access to an oscilloscope but I do have a Digital Multimeter and a soldering setup since I repair medical equipment. Thanks in advance for any help!!
