Question about Philips ProScreen 4600 Impact Multimedia Projector
A green line to the right of the picture and looks like the picture is in 3D
I bumped my screen by accident recently and now have a similar problem (multiple vertical and horizontal thin lines). I was told that the screen is now bad and probably cannot be repaired. The cost of replacement is more than the cost of a new set. Sorry, but that may not be the answer that you are looking for.

Bad news any lines like that mean the communication between the pixels and drivers is broken.
the glue has come loose.
Most will say it cannot be fixed
but there are tricks. it requires the panel to be taken apart.
Only a real tech can fix it.

I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.
The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).

I have this problem on my CPX985w, almost exactly as you describe, I'm going to pull the main board out and check the capacitors, as that seems the likely problem, i'll update with what i find....

You need to replace both convergence ICs they are STK392-120 you will also need about four 6.8 ohm 1 watt resistors. You can get replacement ICs and resistors at the following link and they provide free instalation instructions with pictures. here is the link.
