Got an email back from Icom. Just two brief sentences from them, one saying they no longer have parts for this radio and no longer support it. And the other saying let us know if they can be of any further assistance. Guess this one counts as assistance.

I was hoping they could at least get me in touch with somebody that has quiet a bit of inventory in parts. It?s been such a great radio, might take GalinHdz suggestion, look for a used radio working or not.
A friend of mine that is a bit up on electronics feels like the heat that probably caused the pixels to start burning out.
