i need your help to figure out how to repair my Y580,
first of a video of my problem: gif of broken display
It happens with the start of the laptop and sometimes gets better for a few seconds.
The angle of the display doesnt seem to have an influence on the problem.
Do I have to replace the whole display or could it be a smaller malfunctioning part?
And where can i find a serial number for a proper replacement part?
Thanks in advance!

Hi oreyap ,
Welcome to the Community Forums.
The sample picture may no longer be available and was not able to view .
Anyways, would you see the same display issue on the BIOS screen and / or external monitor ?
Isolating this may help us find the point of failure.
You can use this parts lookup page to find specific part number for your device list and likewise compare it from the FRU list indicated from the hardware manual (LCD FRU page 84) available from the support site.
If issue happens in the BIOS and do not appear on an external screen then most likely an LCD / LCD cable that is affected so that you can initially try to reseat the LCD cable first before deciding on LCD replacement .
You can re upload an image / video of the issue for better description.
Update us how it goes.

Hi oreyap ,
The way it flickers and show the bars most likely be either LCD , LCD cable /board .
Graphics chip and drivers are most likely ok . Try reseating the cables first .
Did you manage to get the part number ?
Do you have the machine number from the parts look up page? Just keep the serial number confidential.
Hardware manual would show gude to reseat LCD components too.
Update us .

Thanks for your answer,
reseating the cable didnt change anything.
The parts look up page doesnt give me any results, on the back of my laptop I have the following but nothing seemed to work (I tried the number after S/N with and without the CB but I didnt get any result):
Lenovo Ideapad Y580
Model Name: 2099
S/N: CB... P/N: ...
MO: CB... FactoryID: ...
On the back of the display it says that it is a LP156WF1 so I guess that this would be a proper replacement display:
Now I have 2 questions:
Could I first buy a cable somewhere and try to rule out that the cable is the issue?
Could i also buy a cheaper replacement display with a 1366x768 resolution, how much compatibility can i expect?

Hi oreyap ,
Specially if there was no noted physical accidents on the LCD , it's worth a try to have the LCD cable ruled out.
You may send me a private message for the SN to check specific part number and likewise , LCD cable may also have a sticker label with the part number too .
About the panel , aside from having a lower resolution from the original LP156WF1 with Full HD , using dual channel cable 6 bit as compared to 1366x768 resolution with single channel . Theoretically downgrade would work as on this discussion . For me, better to check for return options just in case it would not work or ideally get the same LCD using the part number to be on the safe side.
Update us how it would work best for you.
