Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. 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; visit the site linked here...

The problem is most likely a failing electrolytic capacitor in the convergence section of the circuitry. It may not be economically repairable. You can (after unplugging the set) take a good look at all the electrolytic capacitors hunting for signs --crud on the ends, bulging, burning, etc.

My KDL-52W4100 just started doing the same thing. It blurs down the right side of the screen, then goes back to normal after it warms up. Does anyone know whats up with this?

At first, check if battery contacts inside the battery compartment for any dust of rust accumulated. Clean them well, and insert fresh batteries and check. Check its infrared emission. You can check it by using a cellphone with camera option. If there is no infrared emission, you have to check its infrared LED at the front of the remote control for damage or loose solder terminals. For this, you have to open the remote control. If you wish to get more details about how to check and clean a remote control, visit this site. It has a post, that describes how to clean a remote control. Good luck.

The first one i ordered from shopjimmy was faulty, didn't realize until after the warranty so i ate the cost of it (honestly i thought that it was good and there was another thing wrong with the tv) so i said wtf and bought one last week from ebay. Bam! it works great!!!
