 |
|
I've got convergence problems with my Samsung model hcl4715w. Using the remote, I can get to the manual adjustment. The only color out of alignment is RED. I can move the RED vertically, but not horizontally. Does that mean that I will need a new Convergence Module?
I've read other posts that talk about a 'service mode'. Can I get to service mode and make adjustments without leaving my recliner or does it require special equipment or tools?
Thanks for any help and suggestions. |

| Replace your convergence IC's. Should be STK392-040's. Or replace the sub deflection board. # AA95-01846D. |

| minnie is right but just change 2 convergence ics(stk394-040) and check all 3.9 ohm resistors.it will be fine after that. |

The 3.9 ohm resistors are the bias resistors. In any rear projection they are critical. If you change the ic's you should check the surrounding resistors. |
