Any way to fix dead video card without dissasembly?
My Huawei P20 Pro has been working perfectly for about 14 months now. But suddenly It black screened. (Unresponsive screen after 10 second cleaning in sink (IP67))
I think that now about 36 hours later I have figured out that it’s the video card that is being weird. It’s been working to and from since that post. Most of the time it’s black and unresponsive though. When it works it’s usually just for a few seconds and it’s blinking green in some places on the screen. Sometimes it works perfectly though for a few seconds. No screen issues at all. But then after a few seconds, it stops responding to touch and automatically turns off due to “inactivity”. And by that time I cannot click the power button to get it to start again. (But it’s on in the background, vibrating and making sounds etc.)
So my final question is: Is there any way to rescue dead video cards in phones just like you can do with dead PC and Laptop grapics cards (heating them) without dissasembling the phone?
