Toshiba big screen Model TZ50V60 Convergence Issue-Chips Replaced


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. 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, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

You are describing a convergence issue. Rear projection CRT sets use THREE separate color 'guns' that need to be aimed properly every so often, sometimes every month, sometimes once every year, but usually when its moved. Convergence operations are typically a user serviceable function and the process can be started from the menu.  If you have tried doing the user convergence and it is still a bit off you will need to get it to a repair technician that can either fix the power supply or mechanically align the guns.  In my many years of TV experience, rear projection CRT's are typically discarded for two main reasons; either the power supply is causing convergence issues or the blue gun is dull or dead. Either way if you cannot perform a convergence yourself you are looking at $200+ in repair and parts. I would suggest finding a local television repair technician, not many left I know, and get a quote.

50H13 Red Convergence Problem


I do wish people like troylove11 would stop giving advice on things they obviously know very little about. The Toshiba projection sets never have loose connections on the convergence IC's, and there are never bad resistors in those sets. There is no separate convergence board and there are no adjustments on any boards. The convergence adjustments are done electronically, through the remote in the service mode. Also, moving or bumping a projection set cannot cause a solder joint to crack loose. Your set has 2 large convergence IC's and one of them has burned out. This is very common in projection sets. Do not attempt to enter the service mode to make adjustments, because you will only be messing up the correct settings and when the new IC is installed, the colors will still be way out of alignment. Replacing a convergence IC is a very simple thing for an experienced tech, and it is well worth getting the set fixed. If your set uses the STK392-010 IC's, it is probably a good idea to go ahead and replace both IC's with the newer, upgraded STK392-150 IC's. If you have not changed the convergence settings, the picture will return to normal once the IC is replaced and very little realignment will be necessary. When I do a housecall for a set like that it takes about an hour and a half and I charge $150, but shops in your area will vary so ask around.

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.

Use a site like servicemanuals.com and get the service literature for your make/model.Do NOT perform factory reset procedure-that is reserved for when certain parts are changed.You will need the access sequence,adjust info and add to memory step for servicer convergence.Keep in mind--you may have defective convergence IC's.If so,you will have difficulty w/alignment.Use OEM or better IC's no generics!! They won't hold up.
