If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

check all your cables & connections & connections at I/O ports; possibly I/O PCB

Could be in the set but if using a cable or sat box unplug them and wait a while and plug back---I have seen a reboot of a box cure this issue.

1.This issue sounds as though the TV connection circuit has an issue.
2. You have changed the DVR and the HDMI cables and you still have an issue with the video (pink screen) indicates a video circuit issue ( improper voltage or current) at the video section of the circuit.
3. This will require some troubleshooting by a qualified tech.
4. To make sure, try connecting another properly working LCD TV to the cable box or DVR an check.If you get a picture and sound properly it is the TV.
5. Usually a cable box is QA'd (quality assured) by the company and will not be sent unless tested 1st

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...

This model of SONY TV uses a Samsung display panel, the problem you have is the panel went bad.

SONY was offering an extended warranty to change the panel free, please call SONY to check it out that if they still offer the free replacement.

Either someone got too close to it with a magnet or you have an output problem.

sounds like the lcd control board malfuntioned. call sony and im sure they will have you bring it to a repair shop at no charge

Its your receiver, not your tv! Switch receivers and it will go away!
