Hi folks,
Good Prius friend Hobbit has diagnosed a quality problem in the 2004 model Prius, multi-function display. The primary failure symptom is described here:

The "F" series multi-function display has a set of too small pads that can easily result in a failed or failing solder joint. This was fixed in the "G" series MFD:

If you are faced with a non-warranty, MFD replacement, I would recommend taking two hardcopies of Hobbit's web pages to negotiate a better deal. You'll probably need to pay some labor charges but the replacement part should be an exchange. As is true in any negotiation, be patient, stick to the facts and data, be polite and insistent. If necessary, ask to speak with the next level of support. Take notes, be polite and patient.
GOOD LUCK!
