If parts of your screen obey your commandes while other parts do not, or if the whole thing is frozen, replace your conv ICs. On other brands I would suspect cold solder joinnts, but I have not found this on the Pioneers.

They usually use the STK 392-110, but double check on your model. The easiest to get upgrade/replacement, which is much stronger thatn the 110, is the 392-180. I have been having great success with them. Get them at Union Electronics, near Chicago. I believe Melissa is my contact person, but anyone there can help you.

Be generous with the heat sink compound you use - don't starve it, they need that heat transfer from the ICs to the heat sink to be complete and 100%. Clean off all dried out compound from the heatsinks before you put any new stuff on them. A small paint scraper is ideal.

You may have to tighten up your convergence afterwards.

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
