Try this."To open my ICF-7600D loosen (and remove) the two black screws on the L and R top and the two brass screws (one in each battery compartment). Then, because of a lip on the right lower side, open the backside turning it like a page from left to right.Furthermore, like with laptops a strong thumbnail is an indispensable asset for loosening latches." Once you have it open, you can get the schematic [http://stephan.win31.de/icf-7600ds_schematic.pdf|from here] and a bit more of a service manual [http://www.eserviceinfo.com/download.php?fileid=28488|from here] Hope this helps, good luck.
