Re: main factory color settings

You haven't supplied enough information to adequately address your problem. Color drives are not adjustable by the consumer and it would be risky for an inexperienced individual to attempt it. I may be able to provide more advice if you can supply a better description of your problem.

The color is off on the television set. Is this something that I can fix myself?

most of them have the on screen settings, and if this is not working correctly there will be on some but not all a few plastic dials on the main board inside the case that is the factory adjustment, and if your does not have these inside it, then it will be the either the projector lamp or a bad circuit board.

see if there is a "default" option, if not set everything back to the middle, if the colors are still off you sure its not the convergence?
most big screens allow you to change "color temperature" it's like a default adjustment for 3 different brightness levels.... ie...COOL, WARM picture will show obvious changes in brightness

Setting color and focus inside case

The only way to do that is by eye. To Adjust the screen controls the best thing to do is turn them all down then slowly adjust one up until you get retrace lines (arched lines across the tv) then turn it down until the lines re not visible then go about 1/4 turn more, repeat this for the 2 remaining colors, after that its just done to eye for the best color. if you are still having trouble getting the color right you can go in the menu to the video settings and turn the color all the way down then you will have a black and white picture and you can adjust for a perfect black and white picture then turn the color back up in the menu.
As for the focus controls its best done by covering 2 of the tubes so you only have one color on the screen then adjusting to the best looking focus for that color. then repeat this for the other 2 tubes.
If you need more help or clarification please let me know

Hi, I have just purchased the Samsung LE37A559 tv. I have been trying to get the best colour settings brightness colour contrast tint backlight etc. Is there a optimum setting for all of these ? I am...

The problem is that everyone has a different "taste" when it comes to these settings. I like to turn the color all the way down to start with. You should (if the set is factory adjusted correctly) have a black and white picture. If it's not B&W, then there's something inside the set that needs adjusted and you should get a service call. Then I adjust brightness and contrast to get the best B&W picture. Then I turn the color up until I'm happy with the color level, then I adust tint.

Hope that helps

G2 alignments?

Hello YankeeTwidgt,

Here we go you will need a schematic diagram (You may already have one but I thought I would mention it ), an oscilloscope, a TV signal generator (NTSC color bar, RGB purity screens, and pattern screen), and a voltmeter (I would prefer you have a VTVM, but a digital meter with high impedance (>=10M) will be ok).

First turn all of the color and tint controls completely down (This includes the main color and tint and the pre-amp color controls if you have access to them).

Then turn the RGB pots fully counterclockwise.

Once this is done connect the signal generator set to channel 3, and set to the specifications on the schematic, use the color bars, what you should see at this point are bars of various shades of gray.

Then turn the generator to the purity setting and set the pattern to red.

Once this is done your screen should be dark or dark red, gradually adjust the R pot until the screen is pure red and the voltages, and signals match what is seen in the schematic (mark this point on the pot and the return the pot to fully counterclockwise).

Do the same for the Blue and Green Controls (Blue first and then Green).

Once all of the pots are marked and turned to counterclockwise, set the pattern to gray purity, and turn the pots back up to their marked positions, the screen should be gray. switch to color bars and the screen should have the proper colors.

This is a course adjustment, and you will have to do a fine adjustment using the schematic, and the test tools, but this will put you way into the ball park.

The reason these pots are not talked about in gray scale adjustments is because they usually don't have to be touched. That's why it is important to get them back to specification using the voltmeter and oscilloscope to set the signals up properly.

I wish you success,

Main color

The Matrix?? Color converters. Ok Lets assume you mean the screen controls that adjust each color of the Picture tubes?? No you can not. Oh maybe your taking about the convergence? Its only necassary to adjust the lines on the GRID or CROSSHATCH if they are drifting and out of alighnment. You certainly can, if your tweeking the controls all the time, wear them out but that would take alot of tweeking. If your set needs tweeking all the time then there is a problem in the convergence and should be addressed asap or the problem will get worse. ou should never go into a set as theres high voltage even when the set is unplugged for a while and will hurt you bad. Always seek a pro in case you need any internal alighments or tweeking. Good Luck

Projection t.v.

When you say Main color setting, Do you mean your trying to make the colors look better as there are no main color settings but there are main screen controls and this would give the set its B & W settings so then the colors look better. And theres main focus control that would sharpen up the picture. Ok first thing your gonna need to do is Get a service manual so we can find where all the adjustments are. You should ba able to find a service manual if you look in your user manual for a service station for hitachi. Now if your a tech or experienced with tv repair we can go over this but I need to know exactly you are trying to do first Thanks
