-5V Power Problems

-----------------------------------------------------------------------------

  Problems with large hard disk transfers, discolored Toaster output (pink or
  magenta display of white areas), system crashes, or Emplant diagnostic
  failures. (See Emplant Reference.) Solution: U198 7905 -5V regulator is
  probably bad. Replace with new 7905 1-amp -5V regulator (see Sources).

  To locate U198, look near the bottom expansion slot at the back of the
  machine.

  The easiest way to replace this component may be to clip off the leads
  close to the body of the defective part, then trim the leads on the
  replacement and solder it to the old pins.
