I suspect that you have a backlight issue. The backlight is not getting sufficient voltage usually due to a malfunction of the 12V line on the power supply board of the tv or a faulty backlight inverter board. This issue cannot be narrowed down any further without testing it. So if you are handy at fixing electronics stuff and know how to use a multimeter then let me know and I will guide you.

    If you remove the back cover of the tv you will see a board into which the power cord plugs in. That is the power supply. If you can get me the part number off it I can find you a replacement

I replaced both backlight boards but still having problem with LCD TV...it is too dark and color distortion.


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Dark picture means you have low brightness on the screen. Please increase the brightness. Also try increasing the back light intensity.

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


Hi:
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.
