How do you check whether the LCD/OLED panel still works?
Clean sorting before shipment improves estimate quality and reduces differences at intake. The goal is not lab-level testing, but a practical confirmation that the panel still carries real value.
The first test is visual: the image should appear and remain readable.
The panel must stay powered and usable without major blocking failure.
Simple checks before shipment reduce disputes and speed up processing.
Most useful checks
Before packing the parcel, verify the points that actually affect eligibility.
Does the screen turn on?
Is the image visible and sufficiently stable?
Are there fully dead or blocked display zones?
Is the issue related to touch/flex rather than the panel itself?
What can still remain acceptable
A module can keep buyback value even with peripheral issues, as long as the display itself remains technically usable.
Cracked glass.
Surface marks or wear.
Touch issue requiring confirmation.
Why this helps before shipping
If you sort screens by condition before generating the delivery note, you make intake faster, the parcel easier to read and the estimate more reliable.
