Hi Mark,First of all I would like to thank you for consulting Fixya.com regarding on your problem.Your model no. Mitsubishi WD-52525 (
Chassis No. V26) is known for
steady blinking Timer LED fault after pressing the power button key. Once this kind of symptoms is encountered and the unit didn't come on and stuck to this blinking death of life, it means that the
DM board failed to boot up. In normal operation, timer will blink after AC is applied for 80 secs (DM board booting process) maximum before the picture and sound to come on.You've mentioned that you had already reset the unit, unplug and plug back in to the outlet but still the symptoms persist, then this is a clear indication of DM board malfunction. It will not stop from blinking if the faulty parts didn't isoltated.
Good news! because I have a link where you can buy a
