Blue shadow above writing and pictures on screen

I have a panasonic, 49" hdtv 1080i, widescreen, ( off hand can't remeber model #, it's about 5 years old.
When the tv is on it is almost as if the blue convergence is out of sync, and when watching the tv there is a blue image of whats being displayed on the tv but about 4 inches higher on the screen, I have tried to use the remote convergence but it only moves the blue cross up not down.
Also when I use the manual convergence button in the front of the tv, I can fade it max it, but not correct it's position on the tv. To add when I max the blue coloring with the manual buttons in the fron of the tv to max the blue the screen looks as if it is bowed inwards. any help would be great, i was quoted by a few techs they said the buld is gone, which it can't be because it lights up the warning message does not come on and I can alter the blue color. This is a rear projection screen hdtv I am experiencing the same problem on my 61' Panasonic rear-projection HDTV monitor. Model number is PT61HX41

Convergence panasonic HDTV 1080i bbe hi definition


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,Pioneer 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

You can see some more examples and find a fix herebb0cf99.pnghttp://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

I have a Panasonic HDTV 1080i, We started to experience a yellow and blue arc at the bottom of the screen about a month ago. Last night the picture went black. Only the sound is left. What happened?


The convergence IC's are definitely bad. This is a big repair involving taking out the main board and soldering in two new IC's. They are not plug-in components and you would need a professional to do this job.

1. Do I need any additional equipment to watch HDTV broadcasts on my HDTV-compatible TV?
In order to view over-the-air (OTA) HDTV broadcasts, you need to be within the reception area of a TV station broadcasting HDTV signals. Some TVs may require a set-top HDTV tuner and an external antenna to receive the broadcasts. Your cable or satellite provider may also offer HDTV channels as a part of their service, eliminating the need for a separate tuner. Please contact your local service provider to find out what kind of HDTV services they may offer.

2. What is CableCARD and how does it work?
HDTVs with CableCARD slots can accept a small card from your cable provider that allows you to receive standard definition and high definition digital broadcasts without a bulky set-top cable box. Please call your cable company to find out if they offer this service in your area.

HDMI, which stands for "High-Definition Multimedia Interface", is the consumer electronic industry's first connection capable of transmitting uncompressed digital audio/video signals. Components featuring HDMI can transmit both digital audio and video over one convenient cable, replacing the tangled mess that resides behind many home theater components. HDMI also offers improved quality over traditional analog connections thanks to all-digital transmission. Digital sources like DVDs and HDTV programming can now be transferred digitally from source to display without analog conversions that can degrade the original signal.

Unlike the HDMI interface, DVI only handles digital video. Through the use of an adapter, a DVI device can be connected to an HDMI device, but only video content can be transmitted. The audio signal would have to be transmitted through other methods such as analog RCA outputs or an optical digital output.

4. What's the difference between 720p and 1080i HDTV broadcasts? Does my CRT projection HDTV support both?
HDTV signals can be broadcast in either 720p and 1080i. It's up to the broadcaster which signal format to use, and both have their benefits. Our CRT projection HDTVs display 1080i signals in their native format. For 720p broadcasts, you can use the settings on your HDTV set-top tuner, cable box, or satellite tuner to convert a 720p signal into a 1080i signal that your TV can display.

btn_top_gold.gif spacer.gif line_gold.gif spacer.gif spacer.gif5. Why do I still see black bars on my widescreen TV when viewing certain widescreen DVDs and HDTV broadcasts?
Your widescreen TV has an aspect ratio of 16:9 (1.78:1), which is the aspect ratio of HDTV. However, movies are filmed at several different aspect ratios, including 2.35:1. Also referred to as "scope", 2.35:1 is a very panoramic aspect ratio that provides a wide field of view in the theater. Scope is much wider than your widescreen TV, so it still requires the use of letterboxing ("black bars") to fit the entire image on screen. Some TVs and DVD players have a zoom function that allows you to blow up the image so it fills the screen, but the sides of the image must be cropped in order to do so.

6. What will 4:3 broadcasts and DVDs look like on a widescreen TV?
There are multiple settings for adjusting the appearance of 4:3 material on Panasonic widescreen TVs. It can be viewed with black bars on the sides, preserving the way it was originally intended to be viewed. Some viewers find the black bars distracting, so they might prefer one of the stretch modes that lets you fill the entire TV screen with the image. One such mode is the JUST (justify) mode, which stretches only the outer portion of the picture while leaving the center untouched.
