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.

How do I know which part to replace in my LCD TV...is it the backlight or t-con or main board?


Back - light problem. 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.

My Vizio TV has dark spot top left corner


Hi Brandon,
I am afraid that the dark spot in the screen is not repairable. Manage as long as you can or go for a new tv.

I hooked up my cable box up to my sceptre tv and it had sounds but the picture is black and white I even went and bought the blue and green cords but still only black and white


With the blue/green/red cords (Component) you need to get a very good bright light on the connectors so you get the plugged into the correct COMPONENT connectors on the TV. Note, there are white and red AUDIO plugs right near the COMPONENT input so you need to be VERY careful. If you get it wrong, the colors on screen are often off and even black&white.

How is your cable box connected to the TV? Screw on "COAXIAL", Yellow, Red, White "RCA", single flat connector "HDMI" or 5 colored plugs 2 X Red, 1 X White, 1 X Blue, 1 X Green "COMPONENT"

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.

I am hearing a loud hum from the back of my tv. It seems to be louder when there is more white on the tv. When there darker colors on the tv it becomes less loud. Is this a bad thing or is just a function...


Very bad - that hum comes from the power source that is close to death and it's no longer capable of handling the extra power required by a brightly lit screen with ease. Stop the tv open it's back cover and look on the power source for aged components - especially failing capacitor.

Green tint to bright spots on screen


Try to observe the problem when there is a white screen or predominantly white screen. If the screen is green or yellow where it should be white, its most likely a problem with one or more of the small LCD panels in the TV's light engine.

Its an expensive problem to fix. The light engine most likely will have to be replaced. Check with Panasonic customer relations for possible assistance.
