Black screen with 3 colored lines going across

Vertical scan section circuit fault. Check and replace damaged component/s at its vertical scan output section circuit. If you wish to get some details, check the site linked here. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

Have you checked all the connections at the back of the tv?

The vertical output section circuit has the fault. Contact any experienced service technician. This is not a user repairable fault.

Projection sets have two very common problems.

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. 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 more information and a DIY convergenece repair kit with instructions from the link below.

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

*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

Sounds like a bad video card.A video inverter could cause distorted graphics but usually it turns out to be the graphics card.

Your symptoms sounds like a damaged convergence IC’s.

There are two and sometimes three very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

Most of the time you can just correct the convergence through the television menu. All that needs to be done is line up the blue and red to the green. If the colors do not move then there may be faulty components in the convergence circuit.

You may want to consult a Television Repair Technician, or repair this yourself. If you want to tackle this yourself, let me know, I can give you some direction for the repair

I hope this information allows you to resolve this issue.

You have Convergence Failure Problem...

If the lines are slightly diagonal and in red, blue and green you have a problem in the ABL circuit. if the lines are only one color you may take the front grill cover offf and remove the panel. look fro the black box 2 inches square with 6 little controls on it. 3 are for focue 3 are for screen the middle on of the screen is the green adjustment the other 2 should be labled r and b respectivly. what ever the color of the line turn the control labeled screen and r b or g for that color ever so ligtly counter clock wise.

Sound like you lost Vertical Deflection.  Youshould not have a line across the screen because this could destroy the threeCRT Red, Green, and Blue (Picture tubes) if left on to long. There is a protection circuit built in to protect your CRT’s.    Check on the PCB-SIGNALboard (Tuner located on this board) transistors Q-206 Collector should be around 1 Volt Base and Emitter 0V. If the voltage atthis point is greater then 5 Volts the Vertical output IC-401 (Mounted on heat sink 7 pin inline IC) is bad, Part # LA7845.  Pin Voltages should be PIN 1= 0V, 2= 34V, 3= 32V, 4= 3V, 5= 3V, 6= 33v, 7= -6V.  Data sheet located at http://pdf1.alldatasheet.com/datasheet-pdf/view/40357/SANYO/LA7845.html

sounds like bad capacitors on the FMT board need replacing that is a common fault with the first generation DLPs There are 3 bad capacitors.
