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. http://electronicshelponline.blogspot.com/ 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. .

SOURCE: sony bravia kdl 32l4000 - color bars running vertically on screen

In most cases is the screen is covered with vertical lines all the way accross the screen then the T-Con module is at fault. The t-con board is replaceable without having to replace the entire LCD panel which would usually make it cheaper than replacing the TV. The part number I come up with is 1-857-213-11. Please take a moment to rate my answer. Thanks...

it sounds like your back light might be going out. You might be able to fix this by installing a new backlight inverter board.

Looking at a negative screen


Sony Bravia KDL-40V4100 models have a problem with the screen going blank, faded or washed out ( negative ghosting) . It is caused by a bad chip on the T-con board. A replacement chip is available from shopjimmy.com (Sony 55.40T02.C08 T-Con Board Component Repair Kit) for $14.95- If your not an excellent solderer, send your board to them for a repair $69.95.

Could be the power board or main board defective, but I suggest you do firmware update first. Go to http://esupport.sony.com/US/perl/swu-list.pl?mdl=KDL42V4100&LOC=3#div_pos_30 download the software.

Sony bravia KDL-40V4100 audio and picture cycling on and off


I'd say about the blinking to a black screen would be your cable provider. As for the stripes that means that your board panels can be going bad, you can try updating the firmware of the TV to help but if that doesn't work you're getting very close to full failure on the TV.
