Double check all the voltages on the boards and compare. you might have a bad resistor or cap on the board causing this.

If everything above looks fine then your problem sounds like there is contaminated coolant inside the picture tubes and will have to be replaced in all three tubes. Not really a hard job to do as I will post a complete how to do this job. The best way to tell is to turn on the TV set and look down inside each lens. You will see things floating around inside the tube or see a haze on the picture tubes surface. See below for the instructions. Good LuckChanging Projection TV Coolant
1. Tip the TV set so the expansion chambers are pointed up. The expansion chamber is a small white/clear plastic bulb-like thing That is attached to one side of each of the CRT's up near the top lens. In some TVs, the expansion chambers are already pointed up - In this case you don't have to tip the TV
2. Cover the circuit boards below the CRT's with several paper towels to prevent accidentally spilling any coolant onto the boards. The coolant is corrosive and will destroy the circuit boards. Don't skimp on the paper towels here - they are cheap!!!
3. Remove the four screws that hold on the focusing lens assembly and remove the focusing lens assembly.
4. Note the position of the expansion chamber then remove the expansion chamber. It will need to be reinstalled in basically the same position so remember the position or take a picture if you need to. There is a small o-ring on the neck of the expansion chamber where it threads onto the CRT housing - Don't loose it!
5. Use the baster and tube to **** the fluid out from the hole where the expansion chamber was removed. This hole is fairly small...maybe 5/16" or so.
6. Once most of the fluid is out, remove the four screws that hold on the lens cover plate.
7. Remove the lens cover plate, the lens & the large o-ring. (be gentle with the o-rings!!!)
8. Clean the CRT chamber & lens with denatured alcohol. Use 100% cotton balls so you don't scratch anything.
9. Clean the CRT chamber and lens with distilled water. Again, use 100% cotton balls so you don't scratch anything. This will rinse out the alcohol residue. You need to use distilled water for this so there is no mineral residue.
10. Gently clean the large o-ring with distilled water (don't use the alcohol because it might eat the o-ring) Dry off the o-ring and lightly coat it with 100% pure silicone (not siliconized acrylic caulking or acrylic latex caulking - ONLY USE 100% SILICONE). Use your fingers to rub a thin layer of silicone all over the surface of the o-ring. Then place the o-ring in the groove in the CRT housing.

    11. Place the lens in its position on the o-ring. 12. Place the lens cover plate over the lens and install the four screws.
    13. Clean your baster and tubing with denatured alcohol then rinse with distilled water.
    14.
    Use the baster and tube to **** clean fluid from the bottle and install
    it into the CRT through the expansion chamber hole. Go really slow when
    it is almost full to minimize overflow. Wipe up any overflow
    immediately. There will be a small air pocket in the CRT when you are
    done - you will not be able to fill the chamber 100% - This is O.K.
    Just be sure to fill it as far as possible so the fluid is just up to
    the edge of the expansion chamber hole.

    15.
    Install the expansion chamber. Be sure to install it in the same
    position as it was before you removed it. Also be sure that the small
    o-ring is on the neck of the chamber before you thread it on. The
    chamber is just plastic so don't over-tighten it or you might damage
    it. Screw it on as tight as you can go by hand and then give it about
    1/8 of a turn with pliers. (you might have to use needle-nose pliers to
    get a good grip on it.)

    16. Place the focusing lens assembly into position and install the four screws.
    17.
    Turn on the TV and check for leaks over the next 20 minutes. Remember,
    you have not yet removed all the paper towels from inside the TV.
    Remove these once you know there are no leaks. Other things that should
    be done after replacing the fluid include...

    1. Clean the mirror
    2. Clean the top lenses of the focusing assemblies
    3. Focus the CRT's
    4. Adjust the convergence
    Here is a list of things you will need:
    1. Turkey baster
    2. Vinyl tube
    3. Cooling Fluid
    4. 100% cotton balls
    5. Paper towels
    6. Denatured alcohol
    7. Distilled water
    8. Pliers
    9. Screw driver

    To change convergence


    Step 1:

    Look through your manual. Your manual will always give you the most
    specific directions for your particular model. Look for an "adjusting
    convergence" or "set manual convergence" section.



    Step 2:

    Enter the menu on your TV. Use the remote control and bring up the menu.




    Step 3:

    Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."




    Step 4:

    Select a color. You will have red, green and blue to choose from. Do each one, starting with red.




    Step 5:

    Press "Enter." A crosshair pattern will appear on your screen.




    Step 6:

    Adjust vertically. If there is a horizontal red line visible, press the
    up or down arrow keys (or channel up or down) to adjust the convergence
    until the line is superimposed on the horizontal-center line of the
    white crosshair.



    Step 7:

    Adjust horizontally. If there is a vertical red line visible, press
    left or right (or volume up or down) to adjust horizontally. Do this
    until the line is superimposed on the vertical line of the white
    crosshair.



    Step 8:

    Save settings. It is important to save your settings when you are done, instead of simply exiting the menu.




    Step 9:

    Repeat these steps for all colors.

    even if you press every button on the remote, nothing happens when trying to fix convergence?

    Also, can you please not write in capital letters, it makes it look like you are yelling at us.

    Thank you

  • Benjamin Patri
    Benjamin Patri Apr 18, 2008

    sorry, it's harder to read all CAPS, anyway have you checked for contaminated coolant like I first suggested?

  • Benjamin Patri
    Benjamin Patri Apr 18, 2008

    ok sounds good, I don't want you to do something that you don't feel comfortable doing.

    If you need help finding someone to fix it let me know and I can help if you provide information on where you are located.

    I'm sorry that I can't do more but this website is designed merely to give advice so thank you for using Fixya and please don't forget to rate this solution

    Here is a list of good places in your area that you can try, make sure you ask about the cost of servicing the tv before they come and once they look at it so that you aren't throwing money away. good luck and please let me know if you need any more help.

Ok, if it was the spiltter it would be dead, or picture would be doing something differant.
at this point i would check for solder cracks on all convergance ic's as they are big and mounted on heat syncs. also checking vertical ic for cracks and all yoke plugs and connectors. also i don't see a model number so i can't go much more on it, besides, askin you if you try to converge it, do the red and blue move? if not then you def got a prob with convergance ic's. solder them first if doesbt fix, check resisters and fuses incuding all solder in pico fuses. and replace the ic's

    if it does not move in the cross hatch, then you need to replave all convergance ic's and check resisters connecting to them with a meter making sure they match the color code. also check your power supply for fuses and pico fuses(solder in fuses).

    these fuses may also be next to the conv ic's.

    this is your problem.

    ok, then you need to contact your local service tech, this site has a list of them. try and find an autherized service center.

Try to check the connection at the back of TV if they are properly plug in, make sure cables are tightly connected. Loose cabling is one reason to produce those shadows and outline. Try to give TV a little dodge but be careful not to knock it off from its place. Hope that helps.

    If that doesn't fix it chances are you will have to change the lamp for it since you had the TV for quite a while, recommendations are after 3-5yrs to get a better quality output. a typical lamp may cost $200.

  • Edgar Allan Pagayona
    Edgar Allan Pagayona Apr 16, 2008

    Interesting.. unplugging the splitter from the back of the tv are you still getting the shadows/ghosts? If yes, try taking the bulb out and put it back.

    If the splitter has always been there, I doubt it is the cause. It is more likely the TV.

Sounds like your convergence IC chips have failed. You can buy the parts from various suppliers or you can just get a complete repair kit from www.TvRepairKits.com

Picture shadow on rear projection Sony big screen TV


You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.
