    I'm at the step to replace the convergence IC. The replacement IC was purchased as instructed from your link, and was the one pictured in the instructions, which is part number STK-392-180. The IC that is on my set is part number STK392-110. Once again, my set is a Pioneer SD-643HD5(about 7 years old). Is it ok to use one with a different part number( STK392-180 instead of STK392-110)?
    Thanks!

Just fixed the convergence chip problem.$534.00. Now 720p and 1080 1 signals are showing double images and colors. Also the componentinput #2 is showing double images on any format


many of these sets need the convergence adjusted in the 480 and the 1080 separate-- the set most likely if looks good in 480 needs to be adjusted with the original remote in the 1080 mode.

Whoever charged you 534 got you---if you did it yourself you paid way too much--with 1080 signal--enter convergence mode and try to adjust in customer menu--if 480 is ok---it needs to be adjusted in the hd mode.

Yes a simple cable will do it. Look for a converter designed to display a computer vga on an HDMI jack. I have one, and would expect it to work in reverse. My cable has a male VGA like a computer monitor cable.
