Re: Vizio E470VL Dead

I know, I should just buy a new PS and main board, but then again I don't even know if the screen or backlight is any good either. I still cant figure out why the fuse never blew when the surge hit, unless the surge came from the PS3 HDMI cable when the surge hit.

Re: Vizio E470VL Dead

Sorry no pics yet, But the board looks just like this one.

No burn/cracks anywhere on the board but it does have that faint electrical smell. I havent tested anything else yet due to alot

Re: Vizio E470VL Dead

Thank you, I'll get pics up as soon as I can. I just tested the PS_ON pin and got 0V.

Re: Vizio E470VL Dead

Ok, I just did a quick test on the power board. I tested the main big 450V cap and got 178V then I put the ground clip of the digital multimemter on the chassy of the TV and tested:

5V Pin 1 - 5.17V
5V Pin 2 - 5.17V
5V Pin 3 - 5.18V

12V Pin 1 - 0V
12V Pin 2 - 0V
12V Pin 3 - 0V

Is there something wrong with the power board?

New member here. We had a thunder storm a few weeks ago and lightning struck really close to my house, I heard a loud "POP" and in the end my PS3 and my Vizio E470VL got damaged. The TV does nothing, no amber lights no anything.

I turned it in on my house insurance and I got a whopping $376 for both the TV and PS3....argh! The TV repair man quoted $350 to replace a board but on the estimate it did not say power or motherboard so I dont know which one got damaged or if both did. I told him not to fix it for that price.

I want to test the power supply board...
