What does “matrix” mean in this thread?
Here, “matrix” means the laptop’s LCD panel assembly (the screen itself), not the GPU or motherboard. The OP sought a compatible matrix for the Lenovo Y50‑70 after display faults appeared. [Elektroda, Pabloku, post #16687980]
How do I confirm compatibility for my Lenovo Y50‑70 screen?
Open the lid bezel, lift the panel, and read the exact model from the rear sticker. Order the same type and connector. This avoids guesswork between LG LP156WF4 (SP)(L1) and AUO B156HAN01.2. [Elektroda, Przemko21, post #16688000]
Which panel fixed the issue in the thread?
Replacing with AU Optronics B156HAN01.2 resolved pink tint, ghosting, and flicker for the original poster, and issues did not return. [Elektroda, Pabloku, post #16706554]
Are colors and viewing angles better after replacement?
Users reported more vivid colors and better viewing angles after the swap compared with the factory panel. One wrote the replacement looked better overall. [Elektroda, Pabloku, post #16856523]
Could a bad cable cause these symptoms?
Yes. An experienced member advised starting with the display cable before swapping the panel. Quote: “Start with the wire.” This rules out a cheap, common fault. [Elektroda, Przemko21, post #16688632]
What about GPU or motherboard problems?
One risk is a failing BGA GPU/chipset, which can mimic panel faults. If cable and panel swaps don’t help, inspect the motherboard. This edge case was flagged early in the thread. [Elektroda, Przemko21, post #16688632]
How much should I expect to pay for a replacement panel?
A forum member paid about 240 zł for a matte IPS replacement sourced locally in Kraków. Prices vary by region and condition. [Elektroda, arshanter, post #16891209]
Is the fault visible in BIOS or only in Windows?
It showed in BIOS and at the Lenovo boot logo for the OP, indicating a hardware issue rather than a driver problem. [Elektroda, Pabloku, post #16687980]
Did the fix hold up over time?
Yes. After replacement, one poster reported three months of trouble‑free use, suggesting a stable fix when the panel was at fault. [Elektroda, Pabloku, post #16891090]
What symptoms did others see besides a pink screen?
Reports included a greenish tint, ghost images from the previous day at startup, and white horizontal stripes during fast image changes. [Elektroda, arshanter, post #16889658]
Is the factory panel IPS and Full HD on the Y50‑70?
Participants confirmed their original panels were IPS Full HD and shared photos of the label for reference. Always verify yours by sticker. [Elektroda, Pabloku, post #16890525]
Will a replacement panel change how photos look?
One user noticed more vivid colors but also saw image imperfections more clearly, likely due to contrast and sharpness differences. [Elektroda, arshanter, post #16890831]
Quick 3‑step: how do I swap the panel safely?
- Test on HDMI to confirm the iGPU outputs a clean image.
- Remove bezel, read the sticker PN, and check the 30‑pin eDP cable.
- Replace cable if suspect; otherwise install the matching panel.
“Start with the wire.” [Elektroda, Przemko21, post #16688632]
Do I need to move the lid to reproduce the fault?
Not always. One user saw no change when moving the screen, yet the panel was faulty and replacement fixed it. [Elektroda, Pabloku, post #16688006]
Which model would you pick between LG LP156WF4 (SP)(L1) and AUO B156HAN01.2?
The thread documents a successful, durable fix using AUO B156HAN01.2, with improved perceived image quality after install. [Elektroda, Pabloku, post #16706554]
Any statistic from this thread that helps decide?
A concrete data point: one buyer paid 240 zł for a working matte IPS replacement that resolved the fault. [Elektroda, arshanter, post #16891209]
because the motherboard is a bigger problem with laptops. Something this model is faulty, because I have read so many bad opinions about it and the problem with flickering ...
