Question about Mitsubishi WS-73909 73" Rear Projection Television
After unplugging our TV to move it out of it's spot for cleaning the floor, we pluggged it back in, and all that happens if the green light blinking. i tried the "reset" button, and that did not work - no matter how long i held it in, as well as holding the power button - nothing will make the TV come on. what might the issue be?
ONLY 1 or 2 things can cause this problem----First thing to do is
remove front speaker grill--it pulls out and secured with plastic
pegs--behind it you will find an inspection plate---Notice the one or
two pairs of wires coming from the front keyboard
of the set---remove the inspection plate and follow the wires to the
right--you can unplug both plugs(most have two and they are marked with
letters and different sizes so you cannot get them wrong)
The idea here is to remove the front keyboard with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---these sets have a Receiver(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up.
If disconnecting the keyboard allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and or replace it.
If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---you can call them and get a quote for repairing the receiver.
