Re: color problem green and pink

I had a very similar problem - the picture would get garbled, the black colour would turn into dark or bright blue tones, and i would get wiggly/jaggy outlines on the picture wherever contrasting coulours' edges met. After 2 service calls (replaced video boards both times), i gave up and popped the back cover on the TV. I wiggled a cable that connects the video board (it is on the top left quarter of the TV if you are looking straight at the front of it), and noticed that the picture improved right away.

I found that there is a bad solder on the cable connector, and simply keep the cover off now, as the connection will get flaky once in a while (especially in warmer temperatures).

My sceptre lcd tv is displaying really bright pink and green colors

I had a similar problem with blacks showing up as green. Turning up the brightness a bit fixed it for me. Not a permanent fix, but something to try if you want to make it last a bit longer until you can get a new one or fix it.

Contrast really dark but seems to improve after the tv has been on several hours

You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

Hi,Would you pls check the connection that you have made between TV and DVD player..?
2xRCA (white+Red) will go to Audio IN sockets of TV in addition to 1xRCA Yellow video cable goes to "Video IN socket of TV..

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Samsung tv settings

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.
