MSI FX-610 Display behaving strangely

[Darki5000]

Hey there,
recently I've obtained a laptop from a collegue which behaves strangely - to be precise it's its display panel.

- The display flickers in random colors
- When the laptop displays the POST, it looks just fine, for whatever reason. To be specific it looks somewhat fine everywhere until display content hits a specific vertical and/or horizontal line.
You can also watch this mesmerizing mess over here at youtube:

I already tried to error out as much as even possible but now I've run at full speed towards a brick wall.

- The laptop puts out a image over HDMI and VGA just fine:

- The panel itself works just fine when used in another laptop - and vice versa another panel shows the same symptoms on this MSI laptop.
- I ordered a new LVDS cable to be really sure it's not a broken cable, didn't work, problem persists.
- I checked the capacitors next to the LVDS connector and changed them but again no luck.


So, really, what the f is going on here?

Hi, your APU is defective.

Hi, your APU is defective.

That shouldn't be the case here. On the one hand it isn't an APU but a Phenom II x3 P820, on the other, shouldn't the HDMI mirror display the same gibberish if the GPU was defective?

Sorry my mistake about the APU, the problem is not the screen, you changed it, you changed also the cable, the only component you didn't changed is the GPU. The GPU could give you a perfect picture through the VGA and HDMI ports and give you what you observe on the screen of the laptop. The reason is, the picture processed by the GPU doesn't share the same output port, you have a port for the LVDS, one for the CRT, and one for the HDMI. You have three ports because the output signals are not the same.

Thanks a ton!
Just yesterday I've borught it to a colleague who has a reflow oven - and after about an hour the laptop was working again!

I really wouldn't have thought it to be the GPU.
