Re: intermintent picture

Check the horizontal output transistor this could be damage and causing the problem.another thing is pilot light that cause the screen to light up.since this is a projection does not garry a tube.

I have an rca model hd52w67 tv and there is a problem with the picture. the picture has a red and green picture that don't allign by about an inch. I think it is in the picture guns but i cant find a...

Do not align the guns! they are located facing up toward the mirror; they are picture tubes! covered with big glass lenses! heavy!
instead look for a red/green/blue adjustment knob on the set's front; the buttons should say: convergence or, crosshatch push the crosshatch button: once you have three vertical lines crossing three horizontal lines; just merge them using the other R/G/B knobs untill you have one white vertical line and, one horizontal line crossing in the center of the screen.
(you may have to find the controls on the remote using "setup")

Screen is red with lines when channel is changed

If its a kp-51hw40 : go to an unused video input and look at the screen---if it is redish in the background with curved faint trace lines you have one of two things wrong; First: the red "screen" control may be set too high. Second: you may have a problem with the RED picture tube.

To try to adjust the RED screen down you have to remove the entire front grill plate on the front of the TV(some have screws on the back on either side that have to be removed---and then you should be able to pop it out. Behind it there is a masonite inspection plate held in with screws----Once you have that off look for a SMALL SQUARE BLACK PLASTIC BLOCK; it has 6 black adjustable controls---you have to use a flashlight and look carefully---one row left to right will be marked FOCUS--DON'T TOUCH THOSE---THE OTHER ROW left to right will be marked SCREEN; if you look carefully you will see marked by each r (red) g (Green) b (blue)
you want to locate the RED SCREEN CONTROL.

WITH the set still on a blank video input where you can see it clearly turn the RED Screen Control to the left until the lines and red tint go away---do this slowly and make sure you are adjusting the RED screen--not the FOCUS.

IF this has been helpful give me a vote here as I do this for free; yesterday I adjusted one of these in a home that was blue with the faint lines---about 15 minute job for me.

Red/Orange horizontal lines

it could be that the tv convergence circuit is going bad. One shure way of finding out is to go to the tv feature menu(picture,audio etc.) and select the customer convergence setting, you should get a cross hair pattern(cross in middle of screen). that cross should be white and by aligning the red or blue colors they should move left, right, up or down

Picture has gone bad on my 70 in Misubishi

My recommendation is have a svc co. look at it. That model was noted for multiple electrolytic caps being bad and also solder joints. As long as the picture was good prior to your problem then I would say it's worth repairing. I worked on the same model for 3hrs to take care of all the problems and preventive maintenance.

Cannot reset vertical convergance

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,Pioneer2_bing.gif 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
