it depends on what your using it for, adjust colour tones to what you think looks natural, contrast between 80-90, keep sharpness below 30. just have a play around till you find what best suits the source material.

Place the tv on its screen flat on a soft surface,
you need to remove all the screws, not just the stand one marked.
Lift the back panel and then you will be able to slide down the stand, when you have removed the back cover you will also see where how your wall mount will fit to the chassis.
Place all the screws back on the back lid.

Make sure that the closed captioning is turned off. For text and for audio i would suggest check in menu in the audio section for possibly SAP (second audio program) or something similar to this to disable that feature. Let me know how it goes. Jay

Usually it is in the owners manual, but if not, try removing the screws on the back bottom of the base. Just lay that LCD on a flat surface like a bed and then you should be able to see how to remove the base. usually 4 screws. I haven't seen this exact model though. Good luck. Jay

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.

you will need to replace the leaky capacitors in the power supply circuit. You can locate the faulty capacitors with a visual check. Those that are bulging need to be replaced.

Most likely the power supply capacitors. you can identify them by their bulging tops.
