Panasonic PT-LC56E projector

Its the most common poblem with the ax 100-200 projector.Many a times only the ballast requires to be replaced.yet on may occasions both mainboard and ballast requires replacement. its best to confirm with a good known working ax200 and replace first the lamp, ballast and the mainboard.panasonic ax 200 lamps also have failed premature as per my experience.

I have the manual on my computer. It is 32 pages in length. Send me an email: [email protected] Please put Panasonic PT-LC56E as the subject and I will send you the manual. Lawrence Brown

try moving the screen right hand side away or towards the projector to correct the trapezoidal look on the right hand end

After changing the lamp you should be able to turn on the projector and it should run for approx. 10 minutes, allowing enough time to reset the lamp counter. Hit "Menu", select "Option 2", hit enter, which will bring up "Lamp Runtime", press and hold enter button approx. 3 seconds. The selection will change to "Time Reset (Power Off)". Turn off the power and it will reset.

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

You can see some more examples and find a fix here http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

you need to replace or have professional convergence amplifiiers. If know how to desolder and solder you could repair yourself or in home professional tv repairperson will cost you $275-$400. The convergence adjustments via remote are half the battle the IC's loose clarity over time.

your color calibration may be off. see if you can set the red green and blue settings all to "0" and see if that works. may want to refer to your manual and see how you can do that and also see if there is a auto calibration

you need to replace both your convergence ICs they are both STK392-110 you can get replacments at the following link with free instructions with pictures.

I did solve the 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.
