Question about Televison & Video

1 Answer

Samsung model HCN4727W rear projection is having convergance problems. When the perfect focus button is pushed, it can not auto complete. When I try to focus the colors manually, it is not able to correct them. I think it be would be a control board causing the problem since it just went out one day. What part and about how much would it cost?

Samsung HCN5529W 55in Rear Projection can't Perfect Focus


hello What you have is a convergence problem. There is 2 modules inside your set that aligns the colors to have the same geometry and superposed . It is a common problem in rear projection tvs ,
You don`t have to worry about your blue tube , i`m sure it is perfectly fine, it just needs to be aligned through the convergence circuit.
Most often the problem is with those convergence modules that are faulty and need to be replaced.
Hope this will help good luck

"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

Samsung model HCN4727W


I had the same problem with mine until I figured out it was from the auto self focus. Normally it should be done with a picture that remains constant or close to it, or else the focus gets screwed up. Go to menu and setup, then turn the self focus off. If you look on the remote and slide the lower portion down you will see a self focus button. My suggestion is to put a DVD in and hit the pause button and then press the self focus button and wait until its finished.

Prefect focus control


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.
