    Assuming that you replaced Tr4 while there still was another defect part, then there is a good (100%) change that Tr4 is gone again.

  • Issue 2 Failed 48k to 128k upgradeI have been trying to upgrade my Issue 2 with the help of Velesoft, using this schematic; [IMG]http://i764.photobucket.com/albums/xx284/arioch1973/4…

    Can you completely disable the expansion and run it as a 16K machine? If not, then your expansion is not what's failing. Does your computer makes the "buzzzz" noise when you turn it on? If not, TR4 may be broken.
