Question about Mitsubishi WD-62725 62" Rear Projection HDTV-Ready Television
This is a a very frequent problem that occurs in Mitsubishi rear-projection
widescreen HDTV's, referred to as "The Blinking Green light of Death".
This refers to the green LED on the front panel of the TV that normally
blinks when turned on after a power failure or when unplugged: the
green light is supposed to flash for about 1 minute while both
microprocessors boot up: If it won't stop blinking it means that they
aren't communicating w/each other.
To fix this problem, you basically have replace the four (apparently inadequate) 1000uF/16 volt power supply capacitors in the "DM module" (one of the two onboard microprocessors). These capacitors are apparently undersized, in that they will eventually fail (usually after about 3 years) if and inevitably when there are voltage fluctuations in the circuit above 16 volts. (If you Google: "Mitsubishi + Blinking Green Light of Death", it's amazing how many other Mitsubishi rear-projection TV owners have experienced this problem.) It is recommended to install either 1000uF/25 volt or 1000uF/35 volt capacitors as replacements, so that they will be more than ample to handle any voltage spikes that will occur. If you have no expertise in electronic work, then find someone that does, hopefully a friend and this will be a cheap fix for you (under $10 for the parts). Make sure everything taken off is put back on, many times people forget to reinstall the back cover plate for the DM module, which has critical grounding straps essential to the proper functioning of the DM module. After all of this, the tv should work. Let me know how it turns out.
