43H70 Blue Convergence out of line and will not line back up
When trying to get the convergence to line up, the blue will not line up to allow the white cross to focus red, green and blue. This causes the screen when viewing to have a blue outline behind the normal picture. Help would be appreciated.

Re: 43H70 Blue Convergence out of line and will not line...
If the blue colors will not line up, and the blue appears to sag inward from one or more sides, then you can bet that one of your convergence IC's has either cracked loose or burned out. The IC should be resoldered or replaced and the convergence realigned by someone experienced with projection TV convergence circuits.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.
This tv the convergence board are dead.Any colors R,G,B mis alignment,don't matches any colors lines.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts are dead,must be replaced to solved convergence problems.The Shop will cost u $300-350 for parts and labors.
Hello, its very possible there are other color alignments thats out of ajustements and certain color lines will affect each range of alignment and
you will need a tech to come out and check the control unit on your set.
Hi Mark, tough call without putting a scope to the circuit, either the convergence IC`s are going bad, signal from DCU is going bad (digital convergence unit), or possibly bad solder somewhere in the convergence circuit, I`m afraid your going to need a tv tech for that problem, BMW Rider

You have a convergence problem, but you are adjusting the wrong system. You need to adjust the convergence rings first ok You need a dot and crosshatch generator to properly set convergence for this set. Connect the generator set the TV to channel 3 and turn on the generator set it to dots adjusting the convergence try to get the center dot RGB all together and then adjust for the outer edges using the convergence board. the use the crosshatch to adjust convergence along the lines of the crosshatch pattern. Remember use the rings first and the the convergence board adjustments.
