Cracked glass, vertical or horizontal lines, a black display with a working external monitor, or heavy flicker usually mean the panel needs replacing. The safest match is the panel part number on the back of the old screen, because a single laptop model can ship with several different panels.
Five things must match: size (e.g. 14"/15.6"), resolution (HD 1366×768 vs FHD 1920×1080), connector pin count (commonly 30-pin or 40-pin), connector position, and mounting/bracket style. Guessing the pin count or buying by laptop model alone is the most common cause of a wrong screen order.
LapKart lists displays with these specs and a 6-month replacement warranty where applicable, with COD at checkout and Tamil Nadu delivery from Rs 50 (free over Rs 2,000).
Remove the bezel and read the sticker on the back of the panel (codes like N156BGA-EA2 or B140XTN). That part number, plus size, resolution, pin count and connector position, is the safest way to match a replacement.
The pin count is the number of contacts on the screen’s video connector. 30-pin is common on standard HD/FHD panels; 40-pin appears on touch and some higher-refresh or special panels. They are not interchangeable — count the pins on your old screen’s connector.
Connect an external monitor: if the external picture is clean, the fault is in the laptop panel or its display cable. Lines that change when you flex the lid hint at a cable; fixed lines usually mean the panel needs replacing.
Sometimes, if the connector, size and mounting match and the laptop board supports the resolution. It is not guaranteed, so confirm the panel part number and connector before upgrading.
Yes, a replacement warranty (commonly 6 months) shown on each product page, with DOA support and a return process for verified defects.
