Hello all,

I moved my TV and there has been a kind of "split inside". Now I have a kind of white screen. I can see a bit my movie.

It is a Sony Bravia 55XF90.



In general, do you know if it can be fixed or it is the LCD ?

Thanks...

Re: Hyundai W240D

I think I have found the source of the problem. For this, I tried to reproduce the same steps from the last time. I ended up finding a strange issue. When I press well with my multimeter pines ON / OFF and GND ([COLOR="black"][COLOR="black"][B]on the backlight inverter PCB[/B][/COLOR][/COLOR]) to measure the voltage (pins exerting a pressure on PCB (on the middle, where there are no screws)), I put the power with a HDMI source, the screen works again! I remove my pines from my multimeter, the screen does not turn off immediately, but after 2-3secs....

Hello,

Thank you for you answer.
I come back to you as I was in vacation.
Coming back from my vacation and removing the grid to take the pictures, my screen started working again!
Unfortunately, this was short lived as from 1am it does not work: black screen.
What is certain is that the blacklight does not start (in the dark you can not see any difference) even if LED (RED -> BLUE) indicates that screen is ON when I start computer.
Between GND and 24V, I get 24,5V.
Between On / Off (Bright) and GND,...

Hi,

I have some troubles with my Hyundai W240D screen.
I do not happen to have an image on the screen (black screen).
When I connect an HDMI device, LED changes from red to blue (this means that screen is ON) but nothing appears on the screen : black screen
However, I managed to get on for one second the screen looking for the source (VGA) and the screen is off screen once.
I am attaching some pictures of the cards, I do not feel I see HS capacity.
I measured the output of the 2 regulators, I have 3.3V and 1.8V.

thank you...
