My Vip622 was down this morning, no power outage,

Being a newer fridge I would look at the control board being faulty. They do not Handel porters surges very well and you may have blown a relay or resistor on the board. I would install a surge protector on anything you own with electronics in the future.

Have you checked the fuses in the plug and on the fuseboard in your house?

Flashing is either an error code or the set trying to boot up--some of the Mitsubishi sets if power removed will blink for a minute and then stop--then the set can be turned on.

a model number?

1) You performed correct troubleshoot steps down the line.
Last thing would be to install defect timer on another light circuit in house, and see if problem is the timer or wire going to coach lights.

2) EJ351C has 1 year limited warranty.
Buy new EJ351c and install single pole light switch until timer replacement is available.
Timer has easy 2-wire installation. Turn off power. Connect new timer just like old one was connected. Either timer black wire connects to either wire in switch box.

If you temps go up your gonna have to check the control board on the back of the unit.

You can try a new AC adapter.If that does not work,it will need to be repaired by a Nintendo authorized center.(I used to work at one).If you do by a new one PLEASE buy Nintendo brand.The "off" brands usually end up in some kind of problem down the road.
Good luck and agme on!

Can you enter BIOS?

it may be the power supply box

I'm sorry there isn't. Answering machines like this have very little ROM memory. After a powersurge and outage like last night, it wiped the whole memory chip. You can try there support page. It's actually pretty good. http://telephones.att.com/telephones_ui/support/index.cfm

Hope is last to dye. Be calm and contact the technician with best references or Authorized Sony Service. If you need more info please advice
