If you get white/Grey glowing screen, then you need to check and see if the 12vdc feeding the T-CON board went away. See if it looks like the pictures I have here:

Any solutions to my notebook problems


The first thing to always try is resetting your PC. With a laptop, you must unplug it and remove the battery. While the laptop is unplugged and the battery removed, hold down the power button for a minimum of 30 seconds. This will reset the PC. Plug it back in and see if it works now. Always try to reset the PC first, for many different problems.

YES SIREEE, THE BULDGING CAPACITORS ARE MOST LIKELY YOUR PROBLEM. DO YOU KNOW HOW TO CHANGE THEM OUT??? IF YOU DO, I WOULD SUGGEST REPLACING THEM WITH NICHICON OR PANASONIC CAPACITORS.

Powers on and has sound but the screen is always white. Tried the input button, channel button, and nothing changes. The sound works fine and doesnt make any strange noises, just always a white...


It can be the main board is not sending the 12vdc or the signals to the T-CON board, or bad T-CON board, it will require in-depth troubleshooting and an Oscilloscope to find out which baord is bad.

K800i will not charge


Possible to rectify with Wotan Server to repair the EROM which is checked before firmware is flashed. You will have to buy credits and a data cable. Follow instructions pressing key 2 and 5 together. You may as well update the firmware after this process. Google around you will find this is an issue

My vizio vx32L turns on but only a black screen shows up


I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.

HOW I FIXED MINE:Look through the back vents for a white light to make sure the backlight still works. I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine. I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.

Vertical lines on my 40 inch lcd mitsubishi hdtv 1080


Similar problem with an eleven and a half month old LT-40148. Approx. 1 inch vertical banding line on left side of screen on all inputs. After about two weeks, same problem on the right side of the screen.

Fortunately this occurred two weeks prior to the one year warranty expiring.

Called Mits customer service and they referred me to an authorized service center who I happened to have dealt with before.

They picked up the set. The front panel (LCD screen ) had to be replaced. Set was gone for two weeks as parts were not in stock. There was no charge. I hope this screen last more than a year.
