If you can find it inside the set you need to replace R14700. This is the location number written on one of the boards. It is a 27K resistor at 1/2 watt. There was a bulletin by RCA on this problem

SOURCE: dark picture

take the screen off by unscrewing all screws around back of tv. remove panel with a sticker that says " no user serviceable parts inside" remove both screws on each side of screen at bottom with black tabs. there will be 2 screws behind the panel with the sticker on it and unplug the front panel buttons connector. then clean the small mirror with very soft cloth maybe nice cotton t-shirt. be very careful not to scratch the face of the mirror. i would recommend ussing just the cloth but have found isopropyl alcohol to work well if you need to use any liquid.

SOURCE: Picture is very dark

its probably the lamp going bad. dark picture is a pre-cursor to failure. these lamps are supposed to last 2-4 years but for some reason the mitsubishi ones never do. you can replace the lamp yourself, and if it is going bad, you can cool it down, pull it out, and you will see it will look kind of bulged or white in the bulb part. instructions are in your user manual. if it is under a year old, mitsubishi should still cover it. if its just over a year, you can try to call them and complain and maybe they'll back it up. let me know if you need further assistance.

Lg model 47ln5750 screen went black


That model is an LED Backlit unit. The LED driver could be bad or there could be a power supply problem. Sometimes the problem is a cable connection. Is there an picture that you can see in a dark room? If you can see a faint picture, the problem is probably the LED back light.

Monitor dims when we turn lights off in room.


You need to give a more detailed description of the problem.
The LG 47LH90 is an LED backlit TV with 'local dimming' technology. This means that there are lots of white LEDs behind the screen and these can be controlled in groups to allow localised areas of the screen to be dimmed to produce better contrast between light and dark. It is very likely that when the room is dark, this local dimming is more noticeable. The actual individual LEDs cannot be controlled and so the area that is dimmed will generally be greater than the area that is required to be dark 'blooming effect'. In addition, LED backlit displays only maintain their contrast through a tight viewing angle. If you sit too farto the right or left, then light from non-dimmed LEDs will leak through and the screen will look lighter.
In short, there may not be any fault with your TV.

I recently purchased a 47"


Your TV has a light sensor that changes the brightness of the TV based on room brightness.


It's called an "Intelligent Sensor"

You can turn this off in your "Picture" settings.

Congrats on such a nice TV purchase.

If this was helpful, please rank me a 4.

to C_LATKA:
Hi, I recently bought a 47" LCD LG the latest model and I read that you had purchased it previously and I wanted to know how you found the quality of picture on the LCD? At the moment ours is a bit blurry. I hope it was worth buying. Do you think we just need to tune the picture quality?

Projection TV when turned on picture is dark can view slight images until dinning room light is turned on


Try hooking the TV to a different outlet fed by a different breaker. Does the problem go away? If so, the culprit may be a wiring problem in your house that is causing the TV not to get enough power unless the dining room light is on.If in doubt, consult an electrician to make sure both the dining room light and TV outlet circuits are working properly.
