My 60 inch Sony flat screen has a green color to everything. I have replaced the lamp.

Unfortunately most expensive part in your TV - optics block - is gone bad. Sony issued recall that is already expired for most of the models. I would still recommend you to contact Sony and figure out if you still covered under recall. If not - repair might cost somewhere in $800+ range.
Sorry for bringing bad news.
Maybe it's a time for new TV.

Tv gone green/blue and sometimes red in top right corner

If you have a Sony rear projection LCD TV then you have a failing optics block. LCD TV's are not affected by external magnets like CRT TV's were. The optics block issue will only get worse and needs to be repaired by a technician.

My CRT TV has false colours.

The set needs degaussed this is common issue, most tv's have a degaussing coil in them, but they are very weak and will not correct extreme issues. It is possible the internal degaussing coil has stopped functioning. If this is one of these sony 40" crt's this is a big problem. and any metal near by will cause gausing of these tubes. Have a tech come out and degause your tube. A technician will have a very powerful loop coil that will clear the problem with one or two passes. But if it returns, check for perminant magnets near the set like large speakers or any other thing, this can also be caused by a child;s toy with a magnet it it if the child has rubbed it across the screen. This is not a destating issue and can be corrected easly.

Green screen projection

This is the exact same issue as I described for an Epson user. So I'll repeat it here.

I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the green color has gone out. The image is made up of red, green and blue images layered upon the screen. If the green panel has gone out then there is nothing filtering out the green light in the image. This causes a nice green hue to the whole screen.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

1 Answer

Bright green flash and red arching lines

You need to check the bulb in the back of the set as it could be on the way out . just check to see if the bar in the bulb has gone black as it is a good sign the bulb is on it's way out . the bulbs only last 2-3 years or 4000 hours . If thats ok you most probaly have dry joints on the tuner , they just need resoldering
