Stop working went completely dead. no power

The main fuse may be intermittent, causing complete power failure, the other possibility is a defective door switch not operating properly, or loose plug in the power feed, I suggest a technician to take closer look at the system because this could prove tricky to find the culprit.

Completely dead,no LED power light indicator at all?Yes,than u check the power source?Yes,than the tv power supply board is the causes and the problems.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

sounds like the alternator is going out sometimes it works sometimes it doesnt it will blow the battery up if not taken care of

Bill,
I have the same unit. It just happened to me. DId you find a resolution?
I was using it on the oven mode and it just stopped working. It's completely dead.
Thanks
Bob

Your battery went completely dead, it could also be your alternator or youe computer.

My printer stopped working and it turned out to be the power unit.

sucks to hear this but if you had it plugged in when it came back on you fried it

Check the connections at the battery. Be sure they're clean and tight.

Faulty power-supply symptoms:

The front panel display and buttons are completely nonfunctional and appear dead. The unit will do nothing more than display the following messages on the TV screen:

Interface error
(and or)
Interface error! Turn off the power

If a DVD or VHS tape was inserted prior to the error occurring, you won't be able to eject either from that point further. They'll remain stuck inside the unit until you've completed the repair detailed below.
