Autoconvergence Troubleshoot (ERROR display)
When autoconvergence feature is executed and the procedure doesn't complete accordingly by
displaying an error number on screen, check the possible causes in the following order:
1. Make sure convergence and electrical adjustments are properly
set.
2. Check all chassis connections.
3. Check that Autoconvergence patterns are centered and displayed
correctly.
4. Check that K-board is properly connected.
5. Check that optical sensors (screen frame) are properly connected
and working. Check the following error table for possible optical
sensor malfunction or bad connection. In case of malfunction,
replace optical sensor (CD-board).
