Question about Samsung HCL4715W 47" Rear Projection Television

1 Answer

Samsung HCL4715W I attached a crosshatch pattern generator to TV. The convergence is not to bad in the middle of screen but toward the bottom the red line looks like 60Hz signal is affecting the signal. It just goes crazy.

It is very possible that there are some parts in the power supply that are failing. This can be from voltage regulation, filtering, or noise problems.

Your Green CRT is getting Mold in the glycol. This will get worse. You need to drain the glycol out of the crt and clean, then apply new glycol to the crt. You should do the blue one also, because it will go next. The Red can can be left alone.

there is an adjustment called convergence.the convergence setup generates a crosshatch.you need to adjust the red deflection.this is a common thing when the t.v gets moved.the crosshatch or convergence button is mostly on the front control panel.consult the manual for where it is.

Convergence problems


In these projection sets, usually the convergence board has failures. These can be some of the IC's and or a number of the capacitors in most cases.

You will have to call the authorized service rep, or a service center that is familiar with your set and has availability of parts for it.

Considering the age of your set, the risk of investing in to an oder set, it may be a better option to consider a new one at this point.

Samsung HCL4715W 47 in. Rear projectio


IF YOU HAVE DOUBLE IMAGES YOU CAN GO IN THE MENU AND TRY TO ADJUST THE CONVERGENCE, OR US THE AUTO JUST. ON SOME SETS IT IS ON THE FRONT. IF IT DOESN'T CORRECT THE PROBLEM THEN IT IS CONVERGENCE. I REPAIR 2-3 A WEEK. WE DO IT IN THE HOUSE, NO NEED TO TAKE THE SET OUT. MAKE SURE THEY REPLACE BOTH CHIP'S AND THAT THEY USE ORIGINAL PARTS, THE GENERICS DON'T HOLD UP. THEY USUALLY LAST 3-5 YEARS DEPENDING ON THE USAGE OF THE SET.

Red convergence problem


Yes I think the IC's on the convergence board are bad. This board is no longer available from Samsung but is available for repair or a swap from http://www.ptscorp.com. Find the telephone number and call them. or you could replace the two ic's on the board. Good Luck
