If this is a projection tv then the bulbs may be out in the back, double check the mirror alignment in the back that reflects the image on the screen. if neither of these is the issue you will need to take it in for service. There is most likely something wrong with the board. Did this just happen or was there a power surge? I have had my home owners insurance replace my tv for a brown out we had. when working with any item that uses electricty, please be sure to take precautions aginst electric shock, TV's and Microwaves hold a lot of current even when not plugged in.

SOURCE: no picture

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

I have a Mitsubishi WD-62525. In general the picture is great from all sources (cable, component, and hdmi). However, there occasionally are very thin, horizontal lines that flicker across the screen....


I have seen this problem before. It is usually caused by a malfunctioning color wheel. Replacing it should resolve the problem. Let me know if you wish to fix it yourself so that I can find you a replacement.

I have some distored blue color across the screen


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
