    I get a separation of color at the bottom of the screen,along with a "wavy" banding in the same area. Using the auto-sync feature produces the same error as the original poster. When I try to manually adjust the sync (using the numbered grid it displays) the blue "cross" won't move back in sync.

Red Lines through picture when screen is dark, back ground has a red tint. On my 48 "Sony Rear Projection" TV

You can try adjusting the Red color output. (Very touchy adjustment)

If you take off the front cover/speaker cover, there should be a access panel. Behind that, there should be a small square black box with 6 screws on it. This is the focus block. (At least this is where most of them are located)

It sounds more like you may need less red in the mix. There is a screw for each color. R, G, and B. Do not mess with the focus screws, just the ones labeled 'SCREEN.'

Go to an unused input where the screen should be dark. Barely turn the red down in a dark room so that the red spot is at the same level as the Blue and Green.

Use an insulated screwdriver and DO NOT TOUCH the focus block and ESPECIALLY NOT the back of it.
Very HIGH VOLTAGE. I found that out the hard way.

Do not turn any of these up too high or damage may occur and the TV may detect a short and shut off.

I have found that if the three colors are adjusted in a dark room to where the 3 color spots (R/G/B) are just barely visible on the screen at equal levels, there is a pretty good color balance.

I hope this helps! Just be careful.

46 toshiba plasma has red tint in back ground

If you can see the red tint with every input source and also in the On-Screen Menu, then this indicates that the Green phosphor is burning off of the screen faster than the Red and Blue. This is typical of plasma screens. Even if you dont watch a lot of golf or football, green is the most dominent color and burns out of the phosphur pits(pixels) faster than the Red and Blue. Take away green, you are left with Reddish looking screen and Pink whites. This is not repairable.
If the Menu looks nice and white, check your source cables.
Good luck

Toshiba problem!

Your Convergence IC's need replaced. I recommend calling a service company if you want to invest in the repair. Most shops charge anywhere between $250-350.

LP70+ projects a dark rose/pink tint upon the screen

The pink tint produced by my LP70+ projector was not a lamp issue but a connectivity issue. I swapped the old cable with a good known cable and the tint went away.

Pink tint when shhoting in bright sunlight

Sane problem with C713, the view screen is dark and gives focus warning, then the pics come out with a pink tint. I believe it is the sensor or shutter problem. Can't get any solutions either.
