Question about Magnavox 42MF439BF7 42 in. TV
Green power light blinks rapidly. has black screen that only shows the words" digital televison" in bottom right corner. can't change channels or inputs with remote or with controls on tv. it is only 14 months old
I have set with same problem in my shop and after troubleshooting i found that the problem is in jack mo dual A91h5mjc. when you plug set in you hear relay and turn on when you push power switch after few sec high voltage supply shuts down making light blink. what they did is separate high and low voltage supply's half one one board half on other to confuse everyone.

I have the same tv with the same problem. Previously to resolve the issue I have left the system unplugged from the power overnight, however that did not fix my issue this time. Have you discovered a resolution to your problem yet?
