    ik heb hetzelfde probleem heeft u al een oplossing gevonden

    I have the same problem and major red lines over the rest of the screen. i purchased a service manual and opened up the machine. It does not look to me like there are any adjustment of mirror alignment that can be made by me. This just happened out of the blue.

    I basically have your problem, but MUCH more advanced (mine started out like yours).

    The picture below, shows the same screen (or what used to be) as in the photos above.

    My father believes this to be due to capacitors getting old and dying.

    In the OP's case and mine it *might* be the capacitor on the green LCD / sync which is dying.

    My father is an electrical engineer, and so when he has time, will open it up and probe a bit with a volt meter.

    I use this screen daily as a normal TV replacement, and even with this annoying problem (which goes away after 30 mins) feel that the 70" image is much better than my 28" crt ;@)

    Will post back once we have fixed/killed the projector!

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.
Warranty time.

SOURCE: Hitachi 57SWX20B 3D Effect due to green light convergence problem

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).

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.

Obviously, you did not like my last answer but my current answer is the same. YOU NEED TO REPLACE THE LCD ELEMENT OR THE ENTIRE PROJECTOR. There is no other answer, sorry.

Hi Grim159

I've had this once on a Epson Projector and the only way I could this right was by replacing the Mainboard.

Hope this is of help.

Vertical Green Lines

Hi Jon

Check if the lines shows on both PC & Video inputs. If it shows on both you could be in for a new Mainboard.

If it only shows on the one signal and not the other it could only be a loose connector that needs soldering.

HItach cp-s860 problem

I have the same Hitachi CP-S860 and have found the problem is with the convergence on the left and right sides of the picture. The one I am working on has a bad ghosting problem also - you can really see the ghosting when the MENU is on the screen. The center convergence is OK. Following Pics show Circle / Cross pattern - 1st pic the red, green and blue are turned on - 2nd pic shows green and blue on only. I do not have the service manual for this set so I do not know the convergence procedure on this one. I have mostly been repairing NEC, Sanyo, Panasonic and Christie LCD & DLP Projectors.

Discolored image and lines...

I also am having the same problem. at first it only showed up after the projector was on for about 15 minutes. Now I get a purple vertical bar on the right of the screen. I also get vertical green bars spread across the screen.
Does anyone have a diagram of how this machine is assembled?
