Hey, Got this tv for free. Works fine, great picture except that if you unplug it and turn it back on, it goes to test pattern. (red, green, blue gray, black full screen). Menu, inputs and channel info show as they should, so I dont suspect tcon. If I do a factory reset, the tv performs as it should. Only if I disconnect the power does it go back into test mode. Is the eprom corrupt or can I remedy this in service mode? Any ideas are appreciated.

Re: Vizio D55UN-E1 test pattern
You could try and freeze the EEPROM using freezer spray or a can of duster air (and inverting the can) and then power on and see if it starts up as normal.Willing to help but I'm no expert. -

Found a main board on Ebay ($25). I dont know what caused the problem, but so far so good. No more test pattern on start up.Comment
