SOURCE: telivision dont want to power up.

You are experiencing the Mitsubishi Green Blinking Light of Death which is fixable.

All you need to do is replace the four 1000uF/16 volt power supply capacitors in the "DM module" (one of the two onboard microprocessors) which are inadequate for this tv. 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. It is then 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 are good with soldering and know how to work with electronics then this will be an easy fix otherwise I suggest getting someone to replace the capacitors that knows how to deal with them without getting an electrical shock. You can get the capacitors at any electronics store such as Radio Shack.

Good luck and please let me know if you have any further questions.

thanks

If you are using a powerstrip may not be supplying enough power to run the LG HDTV and your HD receiver. If you are using a powerstrip make sure the receiver is plugged directly into the wall. Otherwise this may be a grounding issue please reply if this doesn't work and we can look into some other possibilities.

TV suddenly shut off, blinking red light in power button


The TV's power supply capacitors probably went bad.

Check with a mobile tv repair co. to see if it is worth fixing.
