No this is what we call a "convergence" problem, it is due to burned out component(s) on the main pcb board. You either will need to get it repaired or replace it, replacing it will most likely be the best option.

The blinking green light is a self-test diagnostic code. Please tell me how many times it blinks in between each pause so that I can tell you what the problem is.

You may have failing T-CON board, or worst case will be the LCD pnael itself. You need to have it looked at which will not be cheap!

Use different input cables and check using at list two different input devices (eg. a DVD and a receiver box or a playstation, and the internal tuner).

If the problem depends on the device connected or on the cable, then it is either cable, external device, or the terminal connection circuit in the TV, which in this model is integrated with the TV.

Before testing try doing a power reset by disconnecting TV power cord for five minutes.

If the lower part of the display has a red tint or if it is darker, and problem is none of the above, then the TV is defective.

If the lower part of the screen is reddish, and light is normal, then it is probably the main board. Try going to display settings and change from progressive scan to interlaced (eg from 1080p to 1080i, or to 740i). That may bypass the problem in case the fault is related to progressive scan logic circuits in PC board.
If the lower part of display is darker, then it is a back-light problem. In that case parts to be tested are inverter, psu, pc board and display.

Call Sony right away. They have been having lots of issues with this model. If you are nice (and pleasantly) persistant you may be able to get a replacement at a reduced price. Definately talk to them about repair as well however many report their out-of-warranty (same model as yours) tv was not worth repairing. Many issues on the web for this model. In several of their models over the past 6-7 years there have been many class-action lawsuits. My in-laws got a brand new Sony 52" TV at 1/2 price because of all of the lawsuits over models before yours. They are likely in the mood to work with you right now.
