Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

Hope this will help out in solving the problem......

You will get a white screen when you unplug the t-con from the main board. Doing so removes power to the LCD panel. Verify that all of your voltages from the power supply are correct. If they are, I'd look at the t-con board. It sounds like there is a problem with the t-con that is pulling down the main board.

My lcd monitor produces only white screen...what should i do???


If you olny getting white glowing screen, it can be the connector to the T-CON board on the LCD panel came off or it has blown fuse on the T-CON board, or the logic board is not sending the 5 or12vdc to the T-CON board.

The screen is white.power is on, simply no picture, white screen


Hi:
This could be cause by one to two areas of the unit, first the T-CON board may be bad and second the main system board has failed. The t-con is used to produce the picture on the screen it gets its data from the digital board or system control board. The screen is white because the inverter board is working to light up the lamps.

Screen turned white, only sound to hear


It tuns white because he T-CON board is not working due to blown fuse on the board or it is no getting the voltage from the main board, you can check for voltage at the T-CON fuse, you need to find out if the T-CON board is part of the LCD panel assembly or it is its own assembly, if it is part of the panel, thne it will not be worth fixing since the new screen will be needed.

Cl772b sylvania (model 780) go to white screen after 10 sec power on. No visual signal of damage.


You get white screen glow when the T-CON board on the LCD panel does not receive the +5dvc feeding it or it has blown fuse on the T-CON board, see picture of the T-CON board and the fuse here:

Look at the logic board to see if the ribbon cable may have come off the LCD panel or the logic board, also look to see if you can see any bad caps (leaking/bulging top).

Samsung syncmaster 731bf screen stays white!


It sounds like the T-CON board (part of the LCD panel) is not getting the +5vdc from the logic bd. Check the ribbon cable between the panel and the logic bd. first, then check to see if it has blown fuse on the T-CON bd.

Hello my n71s has been lit white screen and no menu buttons work I can turn off. I tested on other computers and with various resolutions even in safe mode help


When you have white glow and no pictures, then more likely the the LCD T-CON board (part of LCD panel assembly) is not getting 5vdc feeding it, it can be blown fuse on the T-CON board or the logic board is not feeding the 5vdc to the T-CON board.
You need to check the power supply and the logic board first for bad caps (leaking/bulging top).

I am getting a white screen (no picture) on a polaroid LCD


People any lcd tv with a white screen cause by the T-con board if you have some experiences you can check with a multimeter the (smd) fuse on the T-con board it is right in de middel on top in the back of the tv. you might have to move some of the boards to get to it. if the fuse is broken replace it with another smd fuse otherwise relace the t-con.
