Re: Perfect Focus

Perfect "FOCUS" is a misnomer.Convergence is the real issue.Enter servicer mode--perform accurate convergence alignment procedure--activate perfect focus as last step to 100% alignment.If you have a High-Definition source,check procedure for that.

"Perfect Focus" problem on Samsung HCN4727W

You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

Blue blurry on perfect focus

Did you try the manual lense focus in the back? There is a wing nut on it and it's pretty easy to change. You just need someone to look at the TV and tell you when it looks good. Additionally for the Blue tube, it's on the far left. You take off the bottom panel in the back to get to this area. Good Luck.

On the remote you have a door. Open it and you'll find the button focus on the right side the second from up to down. If not is in the menu, go in setup, convergence, auto, ok.

perfect focus functions are based on service mode setup...or factory settings. if the alignment of these setting are loss then the unit wont perfect focus. does the unit have a complete loss of convergence. a complete loss of convergence indicate possible failure of convergence amps.

White tint/haze

Check any/ all pico fuses in power supply. PVAT! Look for evidence of CRT coolant leak. Since Perfect Focus is a function of convergence,you might consider replacing convergence IC's,then perform alignment in servicer mode,then finish w/Perfect Focus.
