Go to the Mitsubishi website, download the upgrade, save it on a flash drive, plug it into your TV, follow directions provided on the website. If you have done this previously, check on website to see if there are any other upgrades, if not, repeat the previous one. This has worked for us. Good luck! Also where you bought the TV may be able to assist you. Mitsubishi will send you the upgrade on a flash drive for a charge.

Does it come and go? I would try reseting the ribbon cables between the LCD panel and the T-CON board first.
The Flexible Printed Circuit BoardS (FPCB) are ultrasonic welded to the LCD TFT panel, they are not SOLDERED on! The connections do get bad due to very delicate nature of how the LCD panels are made. You can also try squeezing the around the top area of the screen where the lines are to see if the lines go away.

If you remove the back and check the power supply you will find a couple of bulged caps that need replace. (eletroliytic), or just replace the power supply module and that will fix your problem.

Hello. I was in a live session with you earlier and it seems like you accidentally closed the window. Does the tv tv click on momentarily before it shuts off and starts blinking?
SOURCE: No sound at all on
Just fixed this on my TV today! (after 2 months of the sound intermittently failing to turn on and failing completely yesterday) Go to Mitsubishi-tv.com. Go to support. Enter your model number. You will be directed to the documentation for your model which will include a zip file for a firmware update and a PDF file with instructions for installing the update. This fixed my sound.
