Try a few things to fix a dead row in an LCD.
Like all flat-screen televisions, liquid crystal displays (or LCD) can suffer a malfunction pertaining to pixel loss. LCDs can have "stuck" pixels, which can affect an entire row. There are a few remedies to attempt prior to contacting a repairman, involving pressure, contrast and heat. Note that if the pixels are black, they are most likely dead, requiring board replacement.
Instructions
Rubbing Out the Problem
1. Use a lint-free cloth to rub the stuck pixels.
Take a clean corner of the lint-free cloth. Using a careful yet firm motion (with the display off), rub the screen in the location of the dead pixels.
2. Displaying bright primaries on LCDs can resurrect pixels.
Download a copy of software that displays a blank image on-screen or find a test DVD (AVIA or Video Essentials) that has test images. Maximize contrast on the display. Play a pattern of solid primaries overnight. Repeat this process if required.
3. Applying small amounts of heat might solve dead pixel issues.
Acquire hair dryer or low-temp heat gun. With the display off, gently apply your heat source to the screen, using a passing motion. Do not bring heat source closer than 10 inches from the screen, and keep it moving constantly. Apply heat for roughly 30 seconds. Wait for it to cool for 10 minutes. Turn on the display. Repeat this process if required.
