Hello,
I have searched everywhere throughout these forums and on the web, and I've read just about every possible scenario of problems with LCD TV's except mine. The closest post that I found was posted by RRR13 about one year ago. Who had a similar issue - read here. So I thought I would get my story out there in hopes that I may be able to help another fellow poor sap with the same exact problem as me.
Here's my initial observations: Black/grey screen when powered on for all inputs and menu screens, but I DO hear audio for all inputs. Vizio logo is orange when off, white when on. Backlight does work like champ.
Observations when I opened it up: I saw no bad capacitors or any visual signs of blown fuses. (FYI-I do not own voltage/wattage testing equipment). I proceeded to plug in power. The T-conn board had a blue LED light that came on along with the backlight when I first turned the TV on. Several seconds after the white backlight came on, the blue LED light faded out to black. I became aware of a very faint hum after about a 30sec. - I believe it's coming from the power board, didn't wanna get my ear too close while the power was on.
My uneducated guess is that the T-Conn board needs to be swapped. I'm trying to think of any other observations. What do you guys think? What else would you like to know?
One other weird thing is that when this all began there were times when the screen did come back to original working perfection when I had the TV unplugged for a while, and then powered it up. The problem is that those moments got fewer and further between as time progressed. I remember the first time I noticed, it was about a week ago. The screen went black and I thought it was the hdmi input. The remote was actually able to change the input and I could then hear the sound from the tv input but the screen was still dark grey. The TV then came back to life and worked without a hitch until about two days ago.
The blackness came again and it was harder to shake that time. I turned the power off, unplugged tv, and held power button down (don't believe this model has a reset but tried anyway) the tv came back on and worked perfect for about 3 hours and repeated the dreadful process. It is now to the point to where the blackness rules, and my movies drool.
Any help is much appreicated! Thanks.
Travis
