Re[5]: Convergence problems on AV-48WP30
Eric Posted Nov 14, 2006, in response to:Barry
You didn't post an e-mail address so I can't send you anything, but read the following.
Check/replace IC804 and IC805 on the Convergence PWB. It is wise to upgrade to two STK392-150. They will run a lot cooler than the STK392-110's presently installed. Be sure to replace them both. Also, check the 6 one watt yoke return resistors. If you don't have an ohmmeter at least check for dark colored bands on the resistor's body. These resistors have been known to open or increase in value.
Remember that the convergence pwb is removed from the front of the set. Also, the ribbon cable that runs from the convergence pwb to the convergence osd pwb is removed from the convergence osd pwb NOT the convergence pwb. It is soldered onto the convergence pwb and trying to forcefully remove it will cause you much grief.
Also, do not operate your TV with the rear cover removed. There is a bulletin from JVC about this.
Good Luck,
Eric

My green is all messed up as well. Just happened - right after the earthquake so I thought that something shook loose, but... I, like all the others, would greatly appreciate all the info (manuals, instructions, etc.) on repairing the convergence problem on our AV-48WP30. This is actually the only problem we have had with our set since we bought it many years ago (2000/2001??).

Sorry I forgot the email address. Thanks for the help. Do you have schematics for this TV?
Thanks again.
