bmarino18,

Initially I would have told you to replace the convergence ICs but after reading your post carefully I think you could have a problem with the convergence box. The lines can only be bent/curved for two reasons. One - the yokes are bad causing an undue strain on the power supply and not being able to correct the problem. Two - the convergence box/board is bad and is not holding the settings causing the curve you see. I cannot tell you which problem you have. You wil have to determine this. I do have a tip at http://www.fixya.com/support/r4273935-replace_digital_convergence_box which may be helpful.

Thanks for using FixYa and for the great rating.

Convergence setup for toshiba 42in projection


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 TV2_bing.gif may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Toshiba 57HX81: Green works but Blue and Red seem to be out.


Do you still have reds? Is the image still clear though discolored? If so you ought to replace the blue bulb which has most likely failed. The part no for the 57HX81 model blue CRT bulb is TOSHIBA     23008753.

Red spot in the middle of the screen


You most likely have a burn in on the surface of one of the picture tubes. What you need to do to confirm this, would be to take off the front screen, and with the set turned on, look directly into each one of the lenses, and see if you see a mark on the green or the blue tube. if this is the case, and I am pretty sure it is, the picture tube will need to be replaced, but this set is not a young thing, as the green faint lines is most likely a bad capacitor in the screen drive circuit. If the picture tube is indeed burned on the surface, most likely be better off buying a new TV set. Good Luck
