Question about Sony KP-48V45 48" Rear Projection Television

1 Answer

Color is weird.

Color is missing. Plenty of blue at all times. Green is good when I adjust hue toward green. But red seems like it is missing. When I adjust to red I get orange. In normal settings picture has orange tint to it and bland.

Tv screen is high in green color what settings do I need to be on


If your TV has a color temperature setting; it is probably on medium. Try it on warm. This will decrease the amount of green and increase the red.

Otherwise you will need access to the tint/hue controls; adjusting it more toward red will help.

Sony 60" HDTV Plasma WEGA....Picture Problem


My guess is that you're not missing the color it just appears muted... That problem is a common one in both the 50 and 60 inch models. And if you change video mode with nothing hooked up you'll see a faint color where none should be...
That's simply dust in the optical block on one of either the red, blue or green lcd panel. Wipe it down with a non-linting cloth and a "light" amount of windex and you're back in business...
But check it out by switchin through the video modes with nothing hooked up.. The faint color you see if the lcd panel that's having the most problem and the one that's muting your green.

My screen has little dots appearing sometimes red sometimes blues behind the picture i just replaced the lamp bulb as i thought it would cure the problem


the projection tube needs to be adjust for color alignment, each tube (red, green, blue) must be aligned so you there would be no color smear appear on screen. if it is aligned try to set up the color balance, hue etc.

There's a green hue over everything


One of your other color tubes( blue or red ), is blown. The green saturation you are seeing is beacuse you are missing a color to complete the picture. Rear projection t.v.'s are pretty cheap to fix with this problem. Just contact a t.v. repairman.

Sony, tv comes on color fine, then turns red


I had the same problem with my TV, but the hue was blue. I was told that not only did I have to replace the picture tube that wasn't staying on, but I would have to replace them all because they would not mix properly. After much investigation, I found that there is an adjustment for a variable power supply to each tube that can brighten and lighten each tube. I adjusted the RED pot and my picture color issue was resolved! To access this adjustment you must remove the front panel on the TV. At the bottom corners there are two small screw covers that you must remove. Then un-screw the screws under the covers. Then pull the front panel off of the TV, (it hooks under the top near the screen so it will swing out from the bottom). Now remove the wooden panel in the center, (four screws). The pot adjustments are at the bottom of the TV. They are marked for Red, Blue, and Green. They are extremely sensitive, don't turn them much! If you over adjust you will get red, green, or blue lines on your screen. Adjust back down to remove these, (this is also the remedy for removing these lines that can appear over time). Good Luck and God Bless!

Blurry screen KP61hs10


Yes, Convergence settings should be tried first before any color adjustment or any fluid changes are done. Remember that there are 3 colors to notice. Red, Green, Blue. The Green is the only one that you can not move with an adjustment The Red and Blue is ligned up on green. Some cases it does matter how linear the Green color is across the board, just how close you get the blue and red on top of green is what matters.

Color problem


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.

Adjusting the color convergence


You are going to have to have the convergence IC's replaced, the only way to correct this I'm afraid. Good Luck
