The Blue gun on my rear projectin TV is off. It


It's not likely as simple as a new resistor. The convergence circuit contains two (sometimes 3 in older sets) convergence ICs which are a common failure point along with a handful of resistors in the same circuit.
This is going to vary a lot by your location but in my experience a convergence circuit repair would run you anywhere from $150 to $250 depending on the price and availability of parts.This is only a ballpark figure. It may be less in some areas, I don't know.

My Toshiba 50H82 television takes about 30 minutes to clear up and during that process, it shakes.It becomes clear but still has wavy lines at the top of the screen which is about 6 inches.


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

This is a convergence issue, the stk392 ic's have failed on the convergence board, if you want to tackle this issue your self you will need soldering skills and a dvm. This is a common issue with all projection tv's.

Problem with convergence


you dont need new CRTs (tubes) you need either the convergence Board or the convergence power supply board depending on the symptoms. If its only one color that is out of alignment its most likely the convergence board. If all the colors are out of alignment you need the convergence power supply board. you can get whichever one you need at the following link as they have both of those circuit boards and have free shipping. Heres the link,
