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

RCA P61927

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

Yes, it could be from the convergence amp having a loose connection. Big Screen tv's have problems with loose connection especially when moved or bumped. If you can take back off and find convergence amps then safely tap on ic's and see if it changes picture then it's maybe just aloose conn. If no change then you need to check resistors inline to red. At the most replace IC's these are the large STK's by a heatsink. Hope this helps!

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.

Perfect Focus 2

Use a site like 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.
