No inputs showing? which board did you change?

There are a few choices here---set does have a hard reset which I can tell you how to access with remote----It is the Option menu--it will allow to reset set to condition it was in when new in box.

Set will turn off, come back on on channel 3 in Air band---

If this information was helpful and you want to know how to get to the Option menu rate this solution as very helpful as I do this here for free.

Check all the flat cables runs between main board and T'Con for and damage or loose contact at both ends. If all are found OK, check the set with any external input; like CD player or VCR. If you do not get any image on screen with these inputs too, its T'Con board is faulty. If you do get images with external inputs, and not with RF or Cable inputs, the Tuner section circuit and the AGC alignments should be checked. In most cases, a main board replacement might need a firmware update too.
Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.

White screen on television/no picture

White screen on TV means that no digital signal is coming from:
1: inputs or
2: TV signal

Generally the problem comes from the wires on the back of the LCD/LED is disconnected. But can also mean the the digital output board has failed or is damaged. If you cannot get the digital setup menu on the screen you will have to have the board replaced at a shop. One thing you can try is to Plug in TV while holding the power button. Sometimes that will do a factory reset. You did not indicate Brand or Model and cannot provide any more tips.

Sony KDL42V4100 - No picture (and no menu), sound only?

There could be several things that can cause this. Could be a bad CCFL bulb, inverter, power supply problem, main board, or T-con. You will need to have the set diagnosed to track down the problem.

My 2003 Sony Plasma television gets no screen. I was watching television when the image froze. I turned off the television, and turned it back on. I can hear the audio from the cable, but I get no picture....

Check all the video inputs. If non of the inputs of video work you need a new Q board, However if your screen doesn't work at all shows no signs of life and you can't access the menu then you will need a new B board.

Vizio lcd sreen fading out.

Well time will tell if this is a true solution but I experienced the same issue. Originally I was able to get the TV to work by turning it off and back on.

After some research I notice the the Vizio FAQ mentions a similar issue for which the solution is to unplug the unit for 3min.

After calling Vizio, they suggested that under the menu option Setup, Picture, Advanced Video Features, I should try turning off Advanced Adaptive Luma and Backlight Control.

My HP turns on but the monitor says there's no video input and the keyboard and mouse aren't working. It worked fine yesterday but when I went to turn it off for the night the screensaver was frozen and...

Ok that sounds like to me that your computer either froze or crashed. Could you please tell me how long you have had the computer? Also what you should do is every desktop comes with a built in video card but what you need to do is go out and buy a new video card for your computer and see if that solves the issue. Also another thing is that if getting and installing a video card doesn't work then you may just need a new CPU board and those aren't expensive at all.

if it affects all inputs including the MENU or OSD on tv .There is a good possiblity your set need a whole new LCD panel .The panel comes withe digital board that when going bad will display weird images on screen.It is not available on its own .It only comes with new LCD panel.If it affects only certain inputs then you have a (B) board bad on tv .So tv might need service in the furture..
