Beratena Agrahara does not sell or fit the panel. SAI Laptop Service does that check in Ganesh Complex, Electronic City, opposite Infosys, above the TVS showroom. Bring the dark laptop before you buy glass.
A black picture is a test, not a shopping list
They look at the panel, a cable, and the board when the image stays black and the fan still turns. A dim or flickering image is inspected the same way. A crack you can see is a different clue. Buying a panel first can mean a part that never belonged in the machine. Batteries, keyboards, drives, heat, and a malware clean remain for other faults.
The test happens on your laptop
You hear whether glass is actually required. The quote comes before paid work, so the wrong panel stays unbought.
Phone 099724 47766 and say the picture is black or dim. The services page, the Beratena Agrahara repair page, and the main hand-in page are the check.
