Blue Horizontal Aligning Adjustment on TP55D81


Can anyone tell me what the problem is here. When in test mode I cannot get the Blue Horizontal to Align. Is this a Blue Tube Problem, a Blue Gun Problem or what?

Thanks in advance

    thanks, that is what I was figuring, I think I am going to give it a try, I feel confident about it. I have found the brand chips. I really don't have much to lose, just would like to give it a try.



    Thanks for your input.

The output IC in the blue convergence section is bad or there is a loose connection in that area .If it is the IC's they are STK392-020. Make sure they are if your going to do this yourself. You would need to check the resistors and fuses that might protect this section . If you take it to a shop avg. price would be 250.00 to $300.00 . More maybe if they come to your house . Do not use gerenic's as they do not hold up as long. Good luck

Green hue from my Mitsubishi xl30u projector. Believe blue filter is shot. I have extra projector for parts. Can anyone tell me (pictures would help) what part to swap to fix this?


If you are skilled at aligning the LCD panels, go for it.
The Blue panel, nearest the light source, has been damaged by heat from an old bulb and needs replacing.

Which service manual setting controls horizontal size?


You're discussing about the factory mode adjustments. The horizontal width adjustments will not be there. You have to adjust it by replacing certain capacitors at the horizontal output stage.

SC 329: Laser Beam Pitch Adjustment Error
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

The LD unit home position sensor does not detect an on condition while changing the LD unit position for correcting the LD position or changing the DPI.


Instructions from the Service Manual below...

.

5.4.3 LASER BEAM PITCH ADJUSTMENT
There are two laser beam pitch adjustment procedures: one for 400 dpi, and one
for 600 dpi. These adjustments use the following SP modes.
· SP2-109-1: Laser Beam Pitch Adjustment - 400 dpi
· SP2-109-2: Laser Beam Pitch Adjustment - 600 dpi
· SP2-109-3: Laser Beam Pitch Initial Setting - 400 dpi
· SP2-109-4: Laser Beam Pitch Initial Setting - 600 dpi
· SP2-902-2, no.12: IPU Test Pattern - Cross Stitch - 400 dpi
· SP2-902-2, no.13: IPU Test Pattern - Cross Stitch - 600 dpi

1. Perform SP2-109-8 (Beam Pitch Data Reset).

2. Input the value for 400 dpi that is printed on the LD unit into SP2-109-1.
Use the value printed after "P" on the new LD unit as shown below.
NOTE: Do not use values printed after a "V".

(These value numbers are on a sticker inside the machine with a UPC code on it. The numbers are just under the UPC barcode. And example number looks like this: "15980300151P: 120, 172", so the example 400 dpi value here is "120".)

3. Press the "Enter" key.

4. Perform SP2-109-3.

5. Print the 400-dpi test pattern onto A3 (11"x17") paper using SP2-902-2 no.12
(cross stitch). (See Service Tables - Test Pattern Printing - Section 4.2.3, pasted below.)

6. Write the value of SP2-109-1 on the test pattern which was input at step 2.

7. Change the value of SP2-109-1 and print another test pattern, repeating steps
2 to 5. Print about 5 patterns with different values for SP2-109-1 (e.g. "48", "96",
"192", "240").

8. Check this test pattern. If the laser beam pitch is not correct, the image looks
like a black vertical stripe pattern.
NOTE: If the laser beam pitch is correct, the vertical stripe is not so noticeable.
If the value is not correct, the vertical stripe pattern is darker.

9. Adjust the laser beam pitch position until the thin lines are of uniform thickness
(no striping effect should appear on the printout), doing steps 2, 3, and 4. (In
step 2, input a value which is estimated to be correct, then do steps 3 and 4,
then if necessary go back to step 2 and try another value.)

10. After adjusting the laser beam pitch for 400 dpi, adjust the laser beam pitch for
600 dpi, using the same procedure as for 400 dpi (use the SP modes for 600
dpi).

.

4.2.3 TEST PATTERN PRINTING (SP2-902)
NOTE: Do not operate the machine until the test pattern is printed out completely.
Otherwise, an SC may occur.

1. Access the SP mode which contains the test pattern you need.

2. Press exit, then touch the "Copy Mode" key on the operation panel to access
the copy mode display.

3. Select the paper size.

4. Press the "Start" key to print the test pattern.

5. After checking the test pattern, exit copy mode by touching the "SP Mode" key.
Reset the test pattern to 0.

6. Exit the SP mode.

These adjusments listed in the manual require removal of a service panel and mechanical adjustment of the laser mounts, so it should be done by a qualified technician.

However, these test procedures can indicate whether or not this is the problem with your printer.

A "Gray Scale" adjustment may solve you problem. If one of the picture tubes is set too high it will cause these RETRACE lines. Then too a weak picture tube might cause this. If the horizontal lines are one color: red, green,or blue then whichever color that is shown would tell you which tube is set too high. Your set has 3 screen controls that control the brightness of each tube. One may need to be turned down a little. Stargazer
