Re: Vizio VO420E Black Screen, HELP!

[FONT="Trebuchet MS"]I haven't been able to check the CCFL's yet, I'm currently at work. I will check them in the morning. It sounds like thats what it is considering I changed the board and it's still doing the same thing. Will I be able to tell immediatly which ones are burnt out or is there a certain way to check them? If it does end up being the CCFL's, where would one go about getting replacements as I haven't been able to find them through the minimal research I've done on them tonight.[/FONT]Re: Vizio VO420E Black Screen, HELP!

Re: Vizio VO420E Black Screen, HELP!

[FONT="Trebuchet MS"]I found this picture while searching on here earlier. This looks identical to my old Power Supply, it had burn marks in the same spot, so I replaced the Power Supply but the new one is doing the same thing, but it isn't burnt up. This is a picture I stole from another thread on here, but as I said, the Power Supply I removed from my TV Friday looks identical to this one, burn marks and all. This poster said he had the same problem as I am having, so he just replaced the caps for the CCFL and his worked perfectly,...

[FONT="Trebuchet MS"]Thanks guys. Where exactly are the lamps located? And how could I check to see if they've gone bad? I called the only local repair place we have around here after putting the new board in, they gave me a flat rate of $ 328 to fix the TV so I'm really hoping to get this thing fixed myself, otherwise I'd be better off just purchasing a new TV.[/FONT]Re: Vizio VO420E Black Screen, HELP!

[FONT="Trebuchet MS"]Sorry if the picture isn't great, had to use my phone. The board on the left is the one I replaced Friday to no avail.[/FONT]Re: Vizio VO420E Black Screen, HELP!

Re: Vizio VO420E Black Screen, HELP!

[FONT="Trebuchet MS"]Just wanted to give an update. I just took the cover back off and tried again, it did the same thing as noted in my original post. I did notice that after turning the power on, I heard a click from the Power Supply, followed by a bright blue LED that only stayed on for 3-4 seconds before going off.[/FONT]Re: Vizio VO420E Black Screen, HELP!

[FONT="Trebuchet MS"]While watching my Vizio VO420E last week, the screen went black on me. I still have Audio, and the Vizio logo goes from Amber to White when turned on, but the screen is pitch black. I was originally told it was the Power Supply over the phone by Vizio. I purchased a new Power Supply (Model # 0500-0412-0750) and put it in yesterday. When I turned the TV back on, I had a picture for about 5 seconds before the screen went black again, so I'm assuming the Power Supply was not the problem. I have done some research and a few people have told me it is the Backlight Inverter,...
