Green out of alignment on samsung rear projection tv


Hi luke I am in the uk and not familiar with this set is it a three tubed crt television or an lcd projector type .. either way what you are descibing is convergence ( three primary colour guns all pointing at the same spot in a nutshell ) in the case of a crt projection tv three tubes one red one green one blue .. there should be a convergence pattern in the menu to re set the convergence via the remote check the manual . If it isn't adjustable you may have a scan coil fault or a tube ie : green with low emission check the green colour gun transistor and associated circuit for leaky caps resistors that have changed value or transistor leakage .. and don't forget the ever popular dry joints on the scan coil plugs .. hope this helps Vortash

Weird convergence


The convergence IC's are the culprit. Its a common fault still for as long as I can remeber projection tvs. Even the front projection types had convergence problems when the manufacturers switched from discret componets to Integrated circuit. Most sets have two IC's some have three. Its always better to change all the IC's at once, as the problem will occour on the others a time down the road, and more labor involved. A typical convergence repair is around 300 or so. Its not a consumer replaceable part unless you have the experience with soldering and know the issues related to the Hi Voltage and safty involved with the serviceing of these sets. Good Luck
