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.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

ok your tv does not come with the very best sound, you have to get a receiver 7.1 or you can use the optical wire , that's if the system you are using has that option.

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

I would venture a guess that the HDMI cable itself is damaged. Try using a different cable.
