43H70 Blue Convergence out of line and will not line back up

You may have pressed a wrong button when in service mode---it allows among other things to turn individual colors off like Blue--to make it easy to adjust red to green first.

Also take a look with set on into the Blue lens to make sure you have a image and it does not look like a blue flood light.

a last note: if you tampered with the lens (they have a wing nut on side that allows them to be turned you may have on the blue turned the lens so far there is no focus---for that lens--Did you?

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.

your convergence ic is defective

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.

Replace both STK392-110 convergence IC's with Toshiba or Sanyo brand........no cheap junk IC's !!!.................T.

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

Hello Renee, 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.
