Perfect Focus 2

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. This is great advice, but, how do I perform all of these steps on my remote? I have a Samsung HCN5527W. Thanks again for your help.

Re: Perfect Focus 2

Use a site like and get the service literature for your make/model.Do NOT perform factory reset procedure-that is reserved for when certain parts are changed.You will need the access sequence,adjust info and add to memory step for servicer convergence.Keep in mind--you may have defective convergence IC's.If so,you will have difficulty w/alignment.Use OEM or better IC's no generics!! They won't hold up.

Green & Blue Ghosting Convergance problem

Odds are real good that the cooling fluid in the green and blue picture tube assemblies has become contaminated. You can tell by looking down into the lenses with a flash light. Funny thing is the red never gets contaminated because whatever organism is causing the problem can't survive in red light. BTW this may still not solve all of your convergence problems but when the colors are so badly diffused the convergence sensors for flash focus can't lock onto the beam landing.

"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

Convergence Problem

Perfect focus in these sets are dependant on factory or service mode calabration. once the unit is calabrated then those setings are stored to be the basis for perfect focus. The fact that you can manual converge the set is a good thing. probaly nothing phycially wrong with your set. However. what is needed is to get a qualified tech to look at your set and to calabrate the convergence.

alignment (in servicer mode) must be accurate within certain

parameters for the Touch Focus function to complete w/o error.

Adjustments should be done in "Full" mode,both HD & regular

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.
