Re: Vizio M550NV Shuts down at startup logo flashes then repeats

How sure are we it's the EEPROM. I can get a Main Board for $150, but I'd like to be reasonably sure

Re: Vizio M550NV Shuts down at startup logo flashes then repeats

So is this something I can replace, I'm very mechanically inclined, have experience with replacing capacitors and I can solder. Would I be better off replacing a board? Does everything sound within spec?

I have a M550NV that won't make it past the startup. It was possibly hit by lightening. Logo flashes between Amber and White, then startup logo displays on screen (backlight works), about 1min 30 secs no response from remote or side control knob. I need any help I can get. I have some experience in fixing flat screens. All capacitors look good, no bubbles or leaks. Backlight and Readings on the Power Supply are as follows

18V Standby = 0.00V, On = 18.17V
18V Standby = 0.00V, On = 18.17V

PWM Standby = 0.00V, On = 3.34V
