Well, I've searched and can't find any info so I'm going to ask. The last two days we've had some really bad storms and tonight I fired up the projector and have no input on port 5. I do still have port 3 but would really not rather drop down that far. Any ideas on what might have gotten smoked? I retubed this projector less than a year ago so I would rather not give up on it just yet. I know it's only a 500 but it's been my baby for quite some time and I'm not ready to put it to sleep quite yet. I've been feeding it with a hacked oppo and ota hd receiver through a Crescendo rgb converter. From what I can tell, it appears that the problem is in port 5 and not any other equipment. Any help is appreciated.

If port3 works, then it must be R761748 switcher board.

Same board is used also in 800, so there are plenty of those around.
