Weird "maze" lines on projected image

An area of the projected image shows weird "maze like" lines, in the green to blue color range.. all lines are 90 degrees to each other, very pattern-like, not random squigles.. i really don't know how else to describe this..
the lines appear brighter depending on the actual image color in the problem area.. the lines do not change position between the wide and normal settings, so i don't think it's a signal transmission issue from the video source..

SOURCE: Long time to power up video

My Sony KP-53XBR200 will not display any video (even from the tuner) except the internal display until it sees a video input on one of the video jacks on the back after a power hit.

I solved this by putting a video cable from Monitor out to Video 4 in (unused for other video). Voilla! Instant video on. This may not be your issue, but it fixed my set!

SOURCE: Picture shows only about a 2-3" blue,green,or red vertical line down the middle

If your seeing vertical line across the screen you need to check the components in the vertical stage as well as the vertical IC could be bad, or the yoke could open.
Also check if any voltage reaching the vertical stage.

Good luck.

Hi 80camaro

You could check in the Service Menu if your RGB is the same percentage and at the same run rate.

The run rate is normally 45-60 and the percentage on 50.

I would however recommend that you take it to a NEC agent to get it serviced.

If this doesn't fix it , then you will be looking at a new Mainboard.

Thanks for using Fixya and good luck.

Can you connect a computer (vga) signal to this projector? I'd like to know what your "white" computer screen does on the projector....example, Excel spreadsheet....

I am leaning towards these problems, a bad video card...or worse delamination of one of your LCD panels and possible polarizer burn in the optical engine.

Best Regards,
Steve

The tv image is showing in three colors....Almost ghost like but in three colors. I checked my connections and tried my blue ray player and the image is still messed up....I did press the magic focus...


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.
You can get a repair kit with parts and instructions from www.TvRepairKits.com

Image is green color............what is wrong with the tv?


It means that the blue and/or red picture tube (bulb) is not working properly. It could be the tube(s) or the circuits that drive the tube. My money is on the circuits.

The picture is showing a double image and is distored.


The problem you are refering to is more than likely a convergence problem. The convergence circuit in your tv is controlled by an IC (integrated circuit) stk392-110 and it makes the 3 colors (red, blue, green) line up/converge together to create a clear picture. You'll know when this part needs to be replaced because the picture you see is 3d looking and possibly bowed on the top or bottom or on the sides in any or all 3 colors.

Tripe image, blue, red and green color on image, not focus


This is a very common failure on Projection TV sets.
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.

Check that the 3 output plugs are in the right sockets (Red, Blue, Green) There is usually a felt pen colored mark on a white tape on the plug in wires. The Board sockets are marked Red, Green, Blue.
