How do I adjust the color contrast on a 1998 GE 19GT320?


one of three things here--if was normal before moved you may have a bad solder connection on the circuit board at the end of the picture tube--happens with age as connections can come loose.

The set MAY have adjustable controls on that board for drives and screens(red, green, and blue) that can be adjusted.

The set may only also have those in a hidden menu.

Considering age of set and cost for a replacement it might be better to replace it if none of above options are something you can try.

The color on my tv is turning green. It's not totally green but it's becoming green. No matter how I adjust the colors it remains the same with too much green. You can't see the true colors...


It is very common for the color of the lamp to change as it nears the end of it's life. Depending on the bulb itself you may see yellow, green, or blue shifts (I have even seen red/orange). This is due to the diminishing output of the bulb and while you can make some adjustment you will eventually hit the point of failure. The bulb could in fact last several more weeks or even months depending on your use and environment. It is probably a good time to start searching for a replacement now so you can replace it as soon as it dies or just replace it now if the color is too bad to be worthwhile.

I have a magnavox big screen tv that was giving to me. i do not have the manuals with it. when i turn it on. the color is in three demension I cannot get it adjusted where they colors are all together.


hi,
first of all check the tint setting on your TV picture menu.
if not get the correct color then, your telivision is a dlp TV that means it have a color wheel in side. if the synchronization of color wheel is not correct this problem can occur. there is a sensor for counting the rpm of color wheel. also have a black mark on the color wheels rotating portion. the sensor scene this black mark for making count. if there is any dust in that portion it will make difficult to the sensor making the counts. you have to remove the color wheel to clean the same.
ok

Picture green with color off mo.av-56p575 jvc


That is a common symptom in projection TVs that use tubes or "color guns" As the set ages the emission in the picture tubes (there are three) begins to slowly fade.

This is unfortunately a normal thing for those older projection sets. A set of tubes will last anywhere from 20,000 to 40,000 hours of operation then they are simply worn out. They can be replaced but I don't recommend it due to the age and technology version of your set. The newer type big screens use a different principle. They either are LCD or Plasma these days. The advantage of the LCD (Liquid Crystal Display) is they are very low in power consumption. The disadvantage is that you can never get a true black, only close. On the other hand the Plasma TVs are more consumptive of power but will give a very sharp image with true black levels. The choice is up to you but I suggest you replace your older television.

My Sony KP-57WS500 TV has curved horizontal white lines. You only see them when there is something dark on the screen. Any ideas?


You have 3 CRTs inside of your TV that create image. Blue, Green and Red. Looks like one of them need adjustment due aging.
Remove front grille. Than remove center "shielding" piece held by 4-5 screws. Behind this cover you will find little black plastic box that have 6 rotating buttons on it. Take you time to study them. There is three columns and two rows. Columns represent color, rows - "Focus" or "Screen". You need to locate "Screen" row of three rotating buttons. They will be marked "B', "G", and "R" for colors accordingly. Turn on TV let it warm up and try to figure out witch color is dominating others on your screen. Then carefully turn rotating adjuster counterclockwise using Philips screwdriver. Try to muscle-remember original position of screwdriver so you can turn it back to it.
Eventually you will find the right one, you will see lines dissapear when you reduce voltage and reappear when you turn rotating shaft back. Sometimes more than one have to be adjusted.
Try to have all three color to be present and visible but with no over saturating and no horizontal lines.
Put cover and grill back - and that's should do it!
Regards.
Russ.

Color of the picture is faded/green


Hello Jdillon917,

I understand what you are saying, however the devil is in the details in reference to your problem. Let me explain, DLP Televisions use what is called "Color Wheel Technology". A wheel made up of primary and secondary colors spin at a synchronized rate with the Luminance Video signal and this along with the changing of the mirrors of the DLP processor creates the color that you see on the screen (This is a high level description, but it covers what is happening). Now what you are experiencing can happen if the sync between the signal to the color wheel and the DLP processor is off center, if the color wheel is out of alignment, or if the signal to the DLP is drifting. The bulb "light" is working but something happened to interfere with the sync between the color wheel and the DLP processor. I would suggest getting this looked at by a DLP qualified TV technician, because of the nature of this problem. In addition I would request that you have the technician do a certified alignment after the problem is taken care of.

I hope this helps,

Thank you,

White colors schemes seem off white color or brownish color and blue has green tint or baby blue color. .


Check the coolant in all three crt's as chances are it is contaminated (should be crystal clear). If brown (beer color), replace coolant in all three crt's and perform convergence adjust. Picture should be like new!!!

Good Luck!!!
