The tv set is 4 years old and this problem started 20 days ago.there is also a thin red line on the upper part of the tv.
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

You will most likely need to replace the panel. You will have to contact Sony and they will send a Factory Trained Technician to your home to replace it. Since you are not on Factory Warranty this repair will cost you. You may find it cheaper just to replace the television.

Both sound like bad LCD panels. The following must be answered to confirm this:
Do the lines appear on all inputs/all signal sources?
Can they be seen in the OSD/menu?
If yes to both questions, it is likely that the LCD panel is bad

LCD correct?
There are 2 types of lines they may be showing, both requiring the replacement of the LCD Panel.
1. Delamination Lines- they are usually multiple vertical lines that do NOT flow from the top to bottom of the screen. Looks look water dripped down or something similar
2. Single/Multiple Vertical lines - This is normally 1 or maybe a few solid vertical lines that travel from Top to bottom. I belive in some cases they may only travel to the screen center.
In both cases, this will always show when the TV is ON. Even if there is no signal being input to the TV. There are other possibilities but these can be the most common. Both require a new panel.

I have a sony KDF-E60A20 projection tv. The picture would go out for about 30 seconds and come back on. It would continue to cycle this way. The green power light would stay on and not flash. The sound would go off when the picture went out and come back on when the picture came back on. I tried taking the bottom cover off the back exposing the fan and blowed it out with a vacuum cleaner, also taking out the bulb and blowing it out. That didn't help. So I ordered a new bulb from Advancedlamps.com and that's what it was. I have now had it on and off for two days and no problems. Cost of lamp was $107.00 including shipping. Good Luck!
