R4755w, yellow tint - Samsung HC-R4755W 47" HDTV

If the yellow tint is uniformly over the whole screen then try changing the video colour tint, hue, phase and other chroma related settings in the menu.

replaced vga cable

you can adjust in color mode. please balance the tint, color,brightness, contrast, & sharpness.

Yes, It could be either your video board or your dmd board, go to the service menu and if the yellow tint is still there, it's your dmd board, if not it will be your video board

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Try this. Worked for me immediately, including with PhotoShop

1. Go to Color Management (in Vista, just click the Windows Orb / Start Search & type in Color Management)
2. On Devices, select your display (repeat if you have multiple ones... at least I did). e.g., Syncmaster ....
   
3. Check the box: Use my settings for this device
4. Select any and all profiles you have and Remove them.

Check to see if that fixed it. You may need to restart. I didn't have to.
