The fault is with its vertical scan output stage circuit. Contact any service technician. This is not a user reparable fault. [Out of Sync: picture].

Screen is bowed on top and bottom.

Projection sets have two very common problems outlined below.

The first common problem is convergence

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. The TV can also shut down when the convergence starts to fail.

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, RCA and others.

You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

Black screen with a line of the picture running

The vertical sweep generator is dead. The circuit that controls the lines being drawn from top to bottom has malfunctioned or died. This not something you can fix, you will need a professional.

Line in the middle of screen

You have a bad component in the vertical circuit of your set. If you hit it on the back of the cabinet with your hand which will "jar it" and the picture flashes back on then you have loose connection. If nothing happens then the vertical circuit has a bad component most likely the Output IC. (Chip) Stargazer

Picture problem

Usually that symptom is caused by cracked solder joints on the vertical output IC. As the IC starts heating up, the picture starts breaking up at the top with several "dancing" dark lines appearing, the top scrunches down and then when the vertical quits altogether, the screen goes completely black. A good slap on the side of the TV might make it happen faster or clear it up temporarily. If you have experience working on PC boards then you can resolder the pins of the vertical output IC but if you have never soldered parts on PC boards then allow a qualified tech to handle it for you.

i dont know this exact model, but i can advice you based on a slightly diffrent model. i hope the solution will be valid for your model as well: TV is digital controlled and have to be adjusted via service menu except the external focus and screen on back of (flyback) high voltage transformer. This is one you can try: Need plastic allen or plastic small flat blade screwdriver to fit these. Focus is top, bottom is the screen that set the overall brightness. Before adjusting, go in menu: press menu once, select picture quality, I think number 4, press 2 for "preset..", press 2 again to select normal. Back out by pressing zero repeatedly. It may ask you to save new settings, select yes. If screen is adjusted too bright, picture look lousy (washed out) the blacks will light up (becomes grey, or visible lines) this means you have actual fault that prevents you to get decent pix, that when it is time to take it in for repair.
