Hi everyone, i have this Toshiba A200 with dedicated graphics card ATI RADEON HD 2600 and 512mb. The display is distorted and i want to know whether it is from the GPU itself or from the memory chips.Thanks in advance.

If you gently flex the board does the pattern change

reflow would do for some time, if you want to do the job done you have to reball them, or buy new ones.

So? What happened?

Because the VRAM can be stuck to the heatsink by the thermal paste, the VRAM can be pulled from the PCB.
