Sony with crazy colors out of whack (convergence)

Hi,
I saw this thread and think my Sony has the same problem--crazy convergence. Was it difficult to fix yourself? Cheaper? Worth the savings? Or do you recommend calling a tech (which I'm guessing will be a couple hundred bucks at least). Any insights/tips would be greatly appreciated, as would some schematics that were mentioned.
Thanks in advance!
Jen

This is a very common failure on Projection sets. Its called a convergence problem.

You may have one or more of the following symptoms.

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • No Audio / No Video - Makes Chirping Sounds

The color is messed up. the color is all different colors like red,green and blue.


Your convergence is out of whack.

This can be caused by a failed convergence IC - or can be adjusted using the Convergence settings in the main menu.

Hi. My Sony Videoscope XBR's Convergence Allignment


I happen to share this same problem. The alignment of the gridlines on the standard convergence panel are completely abnormal, and if I attempt to auto-adjust the TV, it flashes different colors on the sides of the screen , and then turns off the convergence settings.

Replaced ic's. set powers now. now the convergence is whacked.


Sorry buddy , you already know the answer, see the other person that has the same problem , all info with schematic is there, make shure that you replace the resistor and check the vcc to the two ic's, for +/- about 25 vdc. If not there look for burt resistors or fuses.

These set's I just love them, the board can be replace there places were they rebuild them for you. But they charge to mutch. The origenal board was $185.00 not for rebuild board they or $360.00.
Once you think you have solve the problem go the page 46 and try adjusting the convergence, if you need more help email me

Possible convergence problem


You could replace it yourself. I had it done recently and the local repair shop charge $400 to do it (including cost of the chip).

Hi! Guy,
I don't think your problem was caused by lightning. It sound like defective convergence ICs. This must be checked and verified by a qualified service tech.
