Double Letters-One in Green other Red in bottom corner

When looking at the programing menu, on the screen in the bottom left corner words are double printed one in green one in red. As you go up the screen the colors disappear but it looks like there is a shadow effect on the words. Thing look out of focus.

Your convergence has failed. This is a very common problem on most projection tv sets. You can read about it here on fixya using this link

Magnavox tv model 51mp392h/17 words on the bottom are double one set is red other set is green


Thats caused by failed convergence ICs and the 6.8 ohm resistors. You can get the repair kit called the DPTV305 -DPTV345 & MAG01 chassis convergence repair kit which fits your model. The kit has the components and the CD with repair instructions and its available at the following link top of the page. http://tvrepairworld.com/phillips__magnavox_repair_kits

Upper left corner of tv is double image with pink and green


Press Menu on the remote If you see double green, red or blue letters and a part or all of picture looks double, this means the convergence circuit is the problem. A repair like this could be $150.00 and up.
If you're an electronic savvy, you can replace the two chips (stk392-***) yourself.
In this case the 2 black big convergence (both with same part#) chips need to be replaced and without the model# I can't tell which ones they are but they could be one of the following: STK392-110 or STK392-120.
Sometime the resistors around the ICs go bad and you inspect them and measure the with an ohmmeter.

Best of luck

Samsung HCN4727W Rear Projection TV, green screen, audio works


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,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Did you attempt to repair your computer on your own and then started to have this problem or did this just suddenly happen? Also, can you post a picture of what you are seeing?
