Question about Samsung HCL4715W 47" Rear Projection Television

New PCB SUB - But blurry and color off.

Just put in a new PCB SUB because of convergence problem. Convegence is fixed, but a little blurry picture and colors are a little off. I was notified to use the Focus controls and adjust the CRT board dials. The focus controls worked great, but when I adjusted the screen controls on the individual CRT board - nothing happened on all three. I turned all three dials all the way to left and Checked all connections, all plugs and wires in place. Any possibility I received a bad PCB SUB board? Also noticed that the focus worked great on the center of the screen, but the corners are blurry, noticed this when in the convergence mode.

How do I adjust the manual convergence? I am in the settings, but my TV is not letting me adjust anything. I chose the "reset to factory" choice, but that didn't fix the red/green shadows


Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Convergence problem


convergence problems occur alot in these sets. First question you always ask is the picture bowed in at top and bottom. or even on sides. go into customer menu and go to setup. do you have convegence option. if you do not go read fl231 problem in tips and tricks. this could be simple and inexpensive. However it can also be one of three cuicit boards. Next quesiton if you got convegence option does the autoconvergence work. if not how far does it get. then if that doesnt work does manual convergence of blue and red work do the cross hair move at all. if the do or only move one way. it might be convegence amp if not then might be convergence power board.

HCL4715W Rear projection blurry


The focus controls on this set are in the front behind the bezel. I'm not sure, but, I think on this age of Samsung, the screws to the front bezel are on the back side of the set. After removing the screws from the back, the front bezel snaps off and the door behind the bezel need to be removed. Watch the wires connected to the bezel, they need to be attached in order to turn on the set. The focus controls are on a black control block (there are three of them, one for each color). Adjust each color for sharpest picture. I use words on the screen for alignment. Each CRT board has a screen control (Adjust each slowly until retrace lines appear on the screen and then back off until they disappear). You may turn off the color and make sure that the picture is black and white. If it is not, then, which ever color is dominant, back it off a bit with that screen control. Facing the set, Red is left, Green is middle and Blue is on the right. Use only one hand inside an operating television. Do not touch the board, just the controls. This concludes television alignment 101. Any questions respond to this post and I'll reply.
