The picture is dark i changed the settings to make it normal looking but it has gotten worse now it is dark and red tinted please help me find out the problem
First you can up the screen voltage, by finding the HV transformer. It has Screen and Focus control on it this it the Transformer that is in back of set and has an anode lead going to Picture tube. Come up on the screen control slowly and if the picture brightens with vertical lines then it's too high, The red problem is a small transistor that maybe located on the CRT board. It's probably shorted. There are about 3, each going to the different colors Red, Blue, Green.

lg70 nice tv excellent processor just to bad there is no intensity control on color management oh well still better than what the three s are pushing block out the hype lg will be number 1 in a few years haters are starting to come around and well leds coming,
p.s. i dont work for lg just tired of losers bashing stuff because they dont own it. im isf certified those settings are right on the money straighter than a ruler
use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

Most TVs of that caliber have a life expectancy of about ten years.. In 2009 we'll be passing into the HD era and that Tv won't work without a little help from an HD converter.
What you're describing sounds like some transistor problems on the crt board and possibly voltage regulation. Not too expensive for a reputable shop, but my best advice would be to get an estimate first.
If you need help finding a reputable shop contact NESDA, (National Electronic Service Dealer's Assn.) they should be able to direct you to a member's shop in your area. Its like going to the AMA to find a doctor.
If the cost is more than half the cost of buying new - get a new one...
Good Luck
