SOURCE: LG Projection TV has dark picture

Normally the main cause of any DLP having a dark picture is the lamp. I would replace it and it should look like a new set again.

SOURCE: Tv picture quality

You have a defective light engine. We just went through this and we have the same TV that you have. Hitachi knows about the problem but will play dumb when you first call. If you deal directly with their Customer Relations Department 800-654-7013, it will make a lot of difference than regular customer service.

Here's how they handled our situation. We called Hitachi after lots of research online and they gave us the names of some certified dealers in our area. The tech came out and in less than 1 minute said the TV had a defective light engine. We called Hitachi back and low and behold, they are aware of the problem...imagine that. Hitachi called the dealer directly and once the dealer confirmed the problem, they agreed to send a brand new light engine out to the dealer and the tech came out and replaced it. Here's the kicker...Hitachi will pay the for the part ($1500) but they ask you to pay for the install. Our install was $400. This was worth it to us being that we spent $3600 on this set 3 years ago. Once the light engine was replaced, the TV looked BRAND NEW! Please deal with their customer relations department at the number I lised above. If you deal with customer service, they will have you chasing your tail...so to speak! Good Luck! If you're willing to cover the install, the rest should go pretty smoothly..at least it did for us:)

This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

most likely, buy you a lamp and install it yourself, the owners manual tells you how to do this.

the picture getting darker means the lamp has aged and u need to replace it another thing u need ti replace the mirrors in the light tunnel of the light engine they have faded secondly the noise means the colour wheel has aged you need to replace it u will have to replace the whole light engine cos the color wheel comes inbuilt the light engine and u will be ok ontact lg dealer in your area

If your fan motors have alot of bullted up dust in them set will quit playing correctly . Also most of the LGs need resoldering on power supply boards.

I just bought the LG 47LC7DF tv. I would like your opinion on how to set up the tv with the best setting as far as contrast, color and brightness etc


As a rule of thumb, set your picture settings at there bare minimum which is comforttable to watch.

this is so that as the lcd ages, you can increase the settings to compensate - increasing the life of your lcd alot
