I have an older Panasonic Rear Projection HDTV and I just replaced the amp IC's - now the color is off, I can't get a vivid picture. It seems as if there is a greenish tint that I just can't get rid of - - - any thoughts on what this might be?

Re: Green Color Tint
I had a similar problem with my tv. Sometimes it depends where the tv is located, have you moved it? Magnesium in the earth caused my tv to have greanish tints in all four corners of my tv. Try moving your tv forward, backwards, or side to side. Let me know if this works.

My rear projection was doing the same thing. I have a mitsubishi and went into the video/audio set up. When I clicked on video it brought up brightness, tint, color, etc... Not sure if yours is set up the same.
I have an old Toshiba TV and was going to replace it with a new plasma because it has suddenly (the week of July 19, 2010) lost color. It has only green and blue tint. Changing the "tint" on the menu didn't help. The color comes and goes relative to nothing that I can measure, such as how long it is turned on, etc. Reading other complaints from owners of Plasmas, I am thinking it is cable related. I have Charter Cable. Playing a DVD, I have to readjust the tint back to normal. Hope this info gives clues.
First of all, that is not an LCD tv. It is DLP, which is a common mistake because the picture is very similar. DLP tv's use a high-power lamp that reflects light off of thousands of tiny mirrors into a spinning color wheel which gives the reflections color. Each little mirror is one pixel, which can be any color depending on the hole that it goes through on the color wheel. The color wheel may be spinning slower than normal, which could make all of the light go through the green filter on the color wheel, and give your screen a green tint. Have a trusted mechanic take your tv apart and dust the inside. If that doesn't fix it, you may need a new color wheel or bearings for it (that help it spin). You should not pay more than $200 for a bearing replacement on this tv.
Try balancing the tubes out, turn your color all the way down and the brightness in the middle, then find the focus block, it will be a block with 6 controls one row will say screen the other will say focus near the picture tubes, adjust the screen controls(one control for each color) until the picture has a good black and white look to it, then turn your color up and it should look fine. This is how i balance out the picture. But there is another method that allot of techs use, the other method is to adjust the brightness up until you see what is called retrace lines it is a jagged line going down the screen, once you see these lines back the adjustment down just until they disappear. Do this for all three colors. This method works but on an older set can throw the white balance off because of tube wear.

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!!!
Yes,try cleaning your mirror inside of tv they do get real dirty, also clean dirt off of tube lenses there are 3 of them red,green,blue. these are your picture tubes. Thank You for using FixYa and Have a nice Day.
