I have a Teac ctm805sr tv suffering pincushion

Posted on Feb 5, 2014

Fixing a television (as it was given to me). I am hoping to find at least which area on the schematic is related to the pincushion circuit, as this seems to be the only problem with the tv. The first thing I checked was for dry joints or poor soldering. I fixed a couple, but they have not helped, and because of the way the picture went, I would assume that a part was failing at the time, and has now failed completely.

I do not have schematics of this particular model then I would be in better position to find out pincushion problem in your TV. Let me know your findings. If Q405 is short, picture would be hour glass look and if this transistor is open or not being drive, picture would be over sized.
