Question about Televison & Video
Do a reset to this TV, and then check. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.
If a rest too do do not help, the main digital board is faulty, and should be replaced.

I'm not sure how common it is, but I had this problem just recently with my Vizio. The tech came out and replaced the digital converter board and it fixed the pink and green pixels. He replaced the mother board first, but that wasn't it, so he put my old one back in and replaced the digital converter board and that fixed it. I'm not sure if "digital converter board" is the official name for the part he swapped out, but that's what he called it. Hope that helps.

SOURCE: 32" niko lcd-green pixelation
This is probably model OTP-311W. Problem is caused by overheating. Air flow is restricted by plastic grill over fan in back of unit at middle top. To fix, remove four screws retaining grill and fan. Take off grill, leaving fan in place. Replace screws without grill. I had same problem. Since removing grill, have now run unit for over 72 hours without pixelation problem.
