Red clouds on Screen

[Richi_el]

Hello,

i have a device (like a Laptop) wich allways makes "red clouds" on screen.
(see on pic 1)

The device is working normally(all fuinctions) but the clouds in back are allways present. The clouds are moving (see on pic2)

I have tried the graphic card on another device(same) and its still the same.

So iam sure that is not the LCD.
I also tried to reflow the GPU and the Graphic RAM and changed the Grapihc Ram controller TPS51116 but allways still the same.

Have anyone some experience with this fault.

Thanks for supports

Re: Red clouds on Screen

Looks like your LCD cable or LCD itself is bad. Reseat the cable and try new screen
