TV Picture problems

I have a older Panasonic TV, the screen sometimes has a bright line donw the bottom across the screen. And then the actual picture wobbles and ends up moving up the TV screen. So after a while the picture is a third of its normal size and its very annoying.

TV is older and has had a great picture through the years. It has now developed blue vertical lines all the way across the screen every 3/4".


Those are retrace lines from too bright a picture. If you can't get them to go away with the brightness control then a repair is necessary

There is green light in the picture when the TV is on


Sometimes there is interference with another device like a refrigerator that can cause that. they say you can take a magnet & wave it on the green & move it across & off of the screen to try & remove it.

Wavy lines appear across the screen


Projection TV sets have two very common problems listed below.

Problem #1) 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

No picture or just one line across screen on hitachi ultravision rearproj.


Could be a loose connection on the printed circuit board in the Vertical deflection circuit.
You would have to have a qualified technician to repair this problem.
A intermittent connection in the circuit described can cause a horizonal line across the screen.
You have to be careful and not leave the TV on for a period of time with a bright line, as it can actually burn a line on the CRT screens, which is permanent.

PT-47WX, Blue streaks across the screen?


It is not a bulb. It is a picture tube. If there are thin blue lines across the entire screen, not just the edges, and the picture itself looks too blue, it means that the blue picture tube is being driven too hard. This could be because the blue screen voltage is too high, the boost voltage on the blue picture tube is too low, or the video output is leaky or shorted. If the picture has what looks like blue arcs and double images on one or more sides of the picture, it means that one of your convergence IC's has burned out and needs to be replaced. These are things that should be tested and serviced by a qualified tech, so allow an experienced tech to handle it for you.
