Hello!

Re: Vizio e420i-a0 main board problems??

I know this is really old but I am desperate, your story about you TV is the most realtable situation I have read on line about the problems I have. My TV did pretty much the same thing as yours minus the screeching noise which I very well could have looked over. It's been about 8 months TV not working or since the last time a power cycle I tried worked. Ever since then I can't even get it to boot with a power cycle no matter how I've tried it. I just replaced the power supply board in hopes the problem would be redeemed and I could enjoy...
