Question about Gateway PLSM50TV 50 in. Plasma Television
The edges of the "boxes" around "info" are not straight. I can adjust each individual convergence location(0-9) but they seem to change again later. Also, the text on the screen, especially near the edges, shows the misaligned convergence. Have electronics experience, was hoping I could just swap our convergence ICs. 55H70 model.
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV 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, Zenith, and others. You can get a convergenece repair kit from the link below.
Common Symptoms include....
55 INCH TOSHIBA, CONVERGENCE WON'T STAY SET, WON'T - 2_bing.gif"h_mi">Screen looks 3D
Here is a quick test....
Using your original remote go-to the settings menu then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move RED and BLUE in all directions - up, down, left, and right.
55 INCH TOSHIBA, CONVERGENCE WON'T STAY SET, WON'T - 2_bing.gif't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.
Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution
You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com
