With all menu settings appearing with their normal values, my X2 projected image ''oscillates'' between showing correct colours and a heavy green overcast with no blues or whites. The green light is steady (not blinking) and my total lamp hours are just 168. Have I got premature lamp failure?

Installation>Wall Screen>Keystone

The automatic keystone adjustment may not be carried out correctly

because of the ambient temperature and the installation

conditions of the projector and the screen. In such cases, correct

the keystone manually.

• When the projector is projecting images where acceleration is

present, such as in a vehicle and aircraft, the automatic keystone

adjustment may not function correctly. In such a case, set AUTO

KEYSTONE in the INSTALLATION menu to OFF and correct the

keystone manually.

• You can correct the vertical keystones. However, their adjustment
ranges are limited in such correction.

When the keystone adjustment is carried out, the adjustment

value is indicated. Note that this value doesn't mean a projection

angle.

• The allowable range of the adjustment value in the keystone

adjustment varies depending on the installation conditions.

• When the keystone adjustment takes effect, the resolution

decreases. In addition, stripes may appear or straight lines may

bend in images with complicated patterns. They are not due to

product malfunctions.

• Noise may appear on the screen during the keystone adjustment

because of the type of the video signal being projected and the

setting values of the keystone adjustment. In such cases, set the

keystone adjustment values in the range where the image is displayed

without noise.

• When the keystone adjustment is carried out, the image may not
be displayed correctly because of the type of input signal.

convergence prob.

Please do us a favor and rate this solution after reading.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

picture not clear can not adjust on menu what can I do

you have a convergence problem and nedd to replace the convergence ic's i think the part # for the generic replacement is stk392-110-there are 2 of them. you also need to replace( check 1st with an ohmeter) the 4 fuses associated with the power supply going to the convergence ic's-they are solder in fuses and you have to know the value to put in the correct ones. unless you are a technician, i would suggest call for service ont this, but feel free to give the tech this info.

Hello, With most rear projections there is usually an alignment to do with the set up with your TV. This is so the red, blue and green projectors align together to give the correct colouring. This sounds to me what may be causing the outlining of the blue. This can also make it seem off colour. Look in the set up menu of the tv and see if you can find this alignment feature. Usually a cross will appear and you move a blue, red, and green cross with the arrows on your remote to align over the original white one. If this does not work, it may also mean that one of your projectors, that is the red, blue or green one may be failing causing the off colouring. Hopefully this alignment may fix it for you.

first try another computer cable. if same results, press the "auto image" button on the projector. if that doesn't work, press menu, select settings, then factory reset, and "yes". if you still have the same problem, the eca (main board) is bad.

GOOD DAY ND GOOD LUCK;

TRY THIS, IT WILL CORRECT CONCERN:

50V500 ONLY
GHOST: May be described as "Out of Convergence" but ghost is still attached to main image.
CONDITION:
A "ghost image" appearing to the left or right of images in the picture. Can be varying shades of a primary color (red, green, or blue) as well as gray. Can easily be seen in the 4 x 3 mode, at the edges of the picture.
CORRECTION:

To correct the problem, please do as follows:

1. Access I2C Menu. (See page 57 of the Service Manual).
   

1. To enter the I2C Service Menu, with power off, (on the front control panel) press and hold the INPUT button. Then press the POWER button for two seconds. The following Service Menu will appear.
   

Figure 1

1. BEFORE CONTINUING: CONFIRM THAT THE R, G and B DRIVE ARE SET AT 40.
   

• Be sure to press SELECT after each change to SAVE the new Data.
  

1. Using the Remote Control joy stick, scroll down to next page (see Figure 2) until LCD ADJUST is highlighted.
   

Figure 2

1. Move the joy stick to the right to cursor right once. The next page will appear with the word GHOST highlighted.
   
2. Cursor right again, and a white screen will appear with a BLACK SQUARE in the center, as in Figure 3. You will see LCD ADJUST, followed by “SHP” and a number (value).
   

Figure 3

1. If the unit is out of adjustment, you will see a gray ghost on either side of the black square. Move the joystick to the right or to the left until the ghost disappears. The number values will change up or down.
   • If the ghost adjustment is off with a lower value, there will be a ghost to the left of the square.
     
   • If the ghost adjustment is off with a higher value, there will be a ghost to the right of the square.
     
2. Once you get the square to look good without ghosts, press "SELECT" to save any data values that have been changed.
   
3. Press the "EXIT" button three times to return to normal picture.
   
4. Adjustment is completed
   
5. I HOPE THIS WAS HELPFUL, big IRISH.
   

This sounds like your convergence correction amplifiers have malfunctioned. These Integrated Circuits often burn out after a few years (STK392-110) they can be replaced with a higher version (STK392-150) However it is important to have the biasing circuitry checked to make sure nothing has burnt out as a result of the ICs malfunctioning. If you have a background in electronics you can repair this problem with very little effort, however if you do not have a background in electronics, I would suggest that you have your TV serviced by a qualified TV technician.

 

I hope this helps,

 

Thank you,
