Convergence for toshiba 50h82

Just replaced the stk ic's in a toshiba 50h82 and it looks great again, just had to do some minor adjustments in the convergence menu. Was wondering do I need to do that for all of the inputs I use or doing it once will be sufficiant ,also which is better to do the convergence in the regular menu or go into service mode to do it, or is there a difference in the two, as far as adjustments.

Either mode is fine...just save your session when done!

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

Tried to auto adjust the guns, will not come within range


Hi Tod,

If colors do not align correctly, most likely you have a convergence failure. This requires replacement of the 2 STK ICs and possibly some low ohm resistors.

Some Toshiba have a Horizontal oscillator/Drive IC failure that results in a small or shrunk picture (2-3" border on all sides). The 3 colors do not align properly because of the reduced Hor drive signal. The convergence adjust controls will work but not allow good adjustment. Convergence is ok, Hor Drive signal is incorrect.

Many do-it-yourselfers mistake the Hor Drive problem in Toshiba RPTV with convergence failure. Too much adjustment of the convergence controls may cause the saved data to be really messed up and require more difficult alignment in the service mode.

If minor or simple adjustments in the customer convergence adjust menu do not fix your problem, there is a fault. Stop adjusting until fault is repaired

Convergence failure can be accurately identified with the Convergence Gallery on our website. Service in Toronto, Ottawa, Calgary, Edmonton and other Canada cities.

50H82 red wavy convergence (stks didn't fix)


If the tin can module you are referring to is the hyper module, it is common to replace all 11 caps because the factory caps ****. Check for bridged solder connections at STK's search the forum at electromaniacs for 50h81 :)

50h82 red convergence ic replacement


Q783 is a 2SJ512 (FET) with part number 23205037. These are not the easiest to test. If you suspect that it is bad, just replace it. It costs $2.48. I only have a listing for one convergence IC (STK-392-110), but if there are 2, replace the one labeled RVBVGV or just swap the two to see if the convergence shifts from vertical to horizontal.

Keep us posted.
