Question about Toshiba 42H83 42" Rear Projection HDTV-Ready Television

1 Answer

Double Picture My kids kicked a soccer ball into the side of my TV and now there is a blue shadow.  When I use the touch focus the green and red lines are straight but the blue line is bowed, and then I get a touch focus error.  Is this something I can trouble shoot and fix at home?

I have a double image on my screen. When I push

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

Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.

Blue shadow and lines

This would apear to be a convergence issue ..sometimes you can go into settings and converge it manualy.. if this is to far out of range. a service tech will have to adjust inservice mode. if the convergence cuircits are not failing. if so then there are cuircits that will have to be replaced. is this just a blue shadow?.. is there green or red shadows. if not it may not be a major repair.

Blue ghost

If you have the ability to work on solid state electronics and know how these circuits work, you will need to replace the convergence IC's in this TV set. If you do not, call in a pro to assist you in this repair. Good Luck
