Question about Samsung HC-P4752W 47" Rear Projection HDTV-Ready Television

1 Answer

Line at top of screen

I have a samsung HC P4752w Today when I turned on my tv there was a pink and green line up at the top of screen curving down. There was also a little bit of double vision. Towards the bottom and middle of screen the picture is almost normal with just some double vision. Could you please tell me what might be the problem and how I would go about correcting this. My email is ososweet2bme@yahoo.com
Thankyou for any help you might be able to offer.

There are problems in the vertical blanking or scanning circuits. This is not something you can fix yourself at home. It involves troubleshooting the deflection amplifiers and scan generator areas to locate the defective components.

You will have to give the set out for service. I would suggest to get an estimate before proceeding. This type of repair can be costly for the labor to find the fault. If it is only generic type parts involved, the parts themselves will not be too expensive.

I need the outer screen for my Samsung HC-P4752W. Mine has a red line that seems burnt into it. Where can I get one?


It sounds like the RED CRT is cracked which will cause a red line. You can verify by looking into the lens of the Red CRT with a flasnlight if you see a line the CRT needs replacement. If no line then chances are the Convergence IC may have a problem.

Not sure of the part number most use STK392-110 or 120s . You will need to look at the ics in your set they will have the IC numbers stamped on them they will have STKxxx-xxx whatever that number is thats the sanyo part number for those ICs

HC-P4752W Blue Convergence??


You can replace the whole board, or opt to replace just the 2 IC's and a resistor or 2 that has probably failed. Lift the chassis & inspect the pins of the 2 IC convergence chips for hair line cracks around them. Inspect the small resistors out in front of the IC's for discoloring or burnt look compared to other similar resistors. The convergence board will cost much more than having the above repaced. Chips about fifeteen a piece, resisters .50 cents each plus shipping. Convergence board $100 plus.
