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.

Hello,

I'm a 100% certain your LCD panel is bad, I've run across a lot of Sony/Samsung's with the same problem. It can be fixed but involves taking the TV apart. I have 5 flat screens in my home, 3 of them had the same problem yours had, I patched them and they are working fine! A replacement panel will cost more than a new TV set so that's not an option. If you do no wish to fix, I would suggest putting it on Craigslist as a parts unit, someone will buy it. If I have been a help to you please sign my guest book

An out-of-focus picture is usually caused by poor regulation of the Hi-Voltage circuits. In these older Sonys' it can mean poor solder joints in the horizontal output stages. Check all solder joints on the flyback transformer and filter capacitors on the secondary low voltage side. A less common problem would be a short in the picture tube or arcing in the focus block. Any of these problems will require the services of a competent service technician. This old of a set should not be considered for repair, but replaced with a newer flat screen.
