Sony KF-50WE610 - red tint problem

The TV powers up just fine, looking great, but after a while all images appear with a red tint over them. You can still see red, blue, green, yellow, etc but with a reddish even magenta hue over. Ocassionally instead of a red tint we get a blue tint over the screen, no reds can be seen when this happens. No image distortion or sound problems, just problems with the color. We've had this TV since summer 2004, please help.

I have the same exact problem. We found a temporary solution is to give the TV a "love tap" on the on the back beneath where it says "SONY." My guess is something is loose in the back. Make sure you don't hit the TV too hard and try different spots if one isn't working.

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Our Sony Grand Wega suddenly has a green-yellow tint.


IF IT IS HOOKED UP WITH COMPONENT CABLES (GREEN, RED, AND BLUE) FOR PICTURE AND RED AND WHITE FOR AUDIO, MOST LIKELY THE RED ONE IS NOT SEATED PROPERLY, CHECK BOTH ENDS THE ONE CONNECTED TO THE TV AND THE ONE CONNECTED TO WHATEVER THE SOURCE IS ( SATELLITE BOX, CABLE BOX ETC.

Projection has yellow tint


From your description, it sounds like a problem with the blue color. Green LCD=purple onscreen, Red=cyan(baby blue) onscreen, Blue LCD=yellow onscreen. It could be a lot of dust on the blue lcd panel, or worse, might be a burned polarizer filter behind the lcd panel due to excessive heat. If you can focus on the yellow and its tons of yellow specs, its dust. A burned filter however, must be replaced. A technician trained in projectors will have to do it. The filter material is glued to a thin glass panel and is replaced as a single filter. It's a very involved repair.

Green tinted people


The only time I have had issues like this was because of the Component Cables not being in the right position (the Red and Blue connections switched), or a bad Component Cable where the Blue Connection is not receiving a signal. Swap out the cable to be sure and double check that it is properly installed. Green to Green, Red to Red , Blue to Blue.
Hope this helps,

Blue hue accross bottom of screen - Sony KF-50WE610


You can try doing this, turn on the Tv and select the service menu, if that tint also shows on the menu, it's most probable to be your DMD board, but if it doesn't it might be the video board..
