The problem maybe that the fuser is over heating.
If this is the problem than it will most likely need replacing.

    thank you for the tip. i have tseted and inspected the fuser unit and it seems that the right (green connector) thermostat is bad.

Probably fried. Sounds like more of a power surge than a paper jam.

Display stopped working

My Alpine CDA-7842 works fine from a functional point of view but the display (readout) had stopped working. All the lights on the display work but the actual readout is blank. At first the readout would intermittently work now it's completely dead. Any assistance would be greatly appreciated.
