Picture appears concave and doubled


Most likely scenario is that the auto convergence option has disappeared which will cause the set to have an arced picture with double images. You can get the RCA repair kit called ITC222 & ITC222A convergence option missing repair kit from www.tvrepairworld.com which has the replacement parts and the CD with instructions.

The picture projects the image with concave lines on the edges. I'll explain further: somehow the picture is distorted in a way that bends the four edges of the picture in a curved-concave manner so that...


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

Tv picture looks warped


I am Vortash this is a problem we call pincushion where the picture appears bowed or concave . It is a fault associated with convergence problems also green or red lines around people and objects if this is the case on your set try your manual and look up the proceadure for the auto convergence , if you do not have a manual try downloading one from http://www.safemanuals.com for free most likely but there are a few of the more later models they charge for hope this helps regards Vortash

Picture on projection screen is concave in the middle


This set does not use IC's for convergence. Most other brands do use IC's.They use individual transistors in this one and honestly I don't remember ever seeing these go bad. Normally it is the power supply that runs the convergence transistors or more commonly known as the convergence board. It gets pretty technical with this type of problem. Have a repair shop check it out for you and avoid the headache. Thanks

Colors split on my ony rear projection tv


If by a color split, it looks like a 3-D picture, the problem is in the convergence circuit. Since it recovers on its own, it suggests to me that there is a poor solder connection at the convergence ICs. If you can solder, this should be a simple repair. Locate the convergence ICs (large black ICs attached to a heat sink that should be marked STKxxx). Resolder the pins on both ICs. If that does not resolve the problem, let me know.

PICTURE


By the picture that you have supplied with the question you have a rear projection tv. The problem you are describing sounds like you have had the convergence module in your tv fail. Depending on the age and make of the tv, the repair costs ( if out of warranty ) can be prohibitive. The convergence module on rear projection tv's not only is in charge of bringing the 3 different color images together into a watchable picture but also handles the east west correction ( concave / convex aspect to the picture or lack there of ).

Picture has 3 images, all different colors (red-blue-green) screen looks concave in the middle top & bottom


This is what is known as convergence..(very common)... first question DO you have the "CONVERGENcE" option in your setup menu?.... if you dont there may be a special fuse issue... if not then more than likely it is what is known as convergence power supply issue. you have complete loss of convergence?
