First up for discussion is the wittily titled “tapping” technique which involves, well, tapping.  Now, this doesn’t mean the tapping you may’ve already tried; in that you carefully walk up to your beautifully engineered flat screen and whack the hell out of it with your fist.  No.  With the correct technique, you apply a little more finesse.

Leaving the TV switched on, take an eraser or, better still, a pencil with a well rounded eraser at the end, (making sure it isn’t too worn with the metal seat exposed).  Then, delicately, tap the marked area of the screen repeatedly three of four times.  If the problem is not too severe, the pixel should pretty much right itself.

A steady hand will be required for this – to maintain control.  Using the penciled eraser, affords a faster grip, which could help the more unsteady, (or heavy) handed amongst you.  I know this from personal experience.  You will soon know if you are being too hard with your tapping, as the screen beneath where you strike will immediately whiten, and recover to full color slowly.

A variation upon this theme is the “pressure” technique.  Conversely to the tapping technique, this LCD TV repair method requires the unit to be entirely disconnected from any source of power supply.  In addition to the eraser, you will need a very modestly sized dampened cloth.  Ensure to use something that is lint free and clean, to avoid leaving detritus, which could later scratch the screen.

You simply take the cloth, and place it gently over the damaged area.  Rest your eraser gently on the cloth, and begin to incrementally apply slowly increasing pressure.  Do not apply too much pressure, too quickly or for too long.  A steady, well controlled hand is definitely needed for this.  If you have a responsible teenager available, use it!

Reconnect the TV, and as if by magic, your LCD TV repair should have the pixel back doing its job.
