Re: ASUS S301la - strange picture

Ok, a educated myself a little about Edid. I found a tutorial how to read/write screen firmware from linux:

I found the correct bus line for the screen and read the data. Then I compared it to the datasheet:

Suprisingly the data was almost completly identical. The only difference was the header (It was all zeroes, where it's usually mostly FFs).
I've written the binary file as in datasheet and have writen to the eeprom. And then, after reboot...

It's working!...

Re: ASUS S301la - strange picture

The full model number is Vivobook S301LA-DH063H.
I don't see it on Asus page, but it shows i.e. on Amazon and it seems it really uses 1920x1080. And I think it uses EDP, not LVDS translator (as I said original LVDS 720p screen doesn't show a picture).

The screen is AU Optronics B133HTN01.0 (HW 0A FW1). Is there a way to find out is it the part number used originally?
I don't really have a way to program a Edid eeprom (kinda newbie here). I guess I would need a programming board and take out the chip? Is it on the ma...

I turned out it kinda is working, after connecting to external monitor through HDMI port, the picture was there and the system works fine.
I decided to try and get to the bottom what is wrong with it - and I did, partially thanks to the information and boardview I found on this forum - thank you!
There was a short on the lcd power circuit and after...

Hi, I'm Pawel. I'm a 32 and I'm a programmer.
Having some free time at the moment and I've decided to take a look at the laptop I had my hands on with no picture (Asus S301la) and found this forum when looking for schematics.
I only have some basic electronics knowlege and this forum seems very informative and helpful. Thank you all.
