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

1 Answer

Samsung HC-P4752W Ghosting, seeing yellow, bowed lower left

When I turned the TV, it looked blurred, or 'ghosting', with yellow onto the left. Any kind of words that are on the screen are in 3d. Is this a indication that the CI's are burnt out. If so when I take the subboard out how do I remove the Old CI's? I know I must solder but any advice would be greatly appreciated.

    I got into the service mode of the Samsung and all I see is lines. How do I go about understanding how to adjust the lines using the remote. Will I need to dl the 15.99 Service Manual to know the buttons? Thanks so much Shuttle!

What might be happening is that your convergence is out of adjustment. Before removing the Convergence ICs try to adjust your convergence either from the onscreen adjustment (see your owners manual) or by using a signal generator (if you have one). I am against this "lets start swapping parts out" craze that has become the norm because you never fix the cause of your problem just the symptoms. I would suggest trying to adjust the convergence first. Thank you, Shuttle83,

    The adjustments differ from remote to remote and from system to system. So, I would suggest getting the service manual and go about things the right way. If the problem can be fixed with a $15.99 manual vs 2 $16.00 IC chips I would say you have come out on top of things. The pattern you see is called a crosshatch about 9 - 10 lines running horizontally and vertically these are used to adjust convergence in the center ot your screen and the upper right and left quadrants and the lower right and left quadrants. I can tell you that the most important adjustment is the center adjustment, the the upper and lower quads as close as possible and you will be ok. I say buy the manual so at least you will have it just in case you ever need it.

    Thank you,

I have a Samsung HC-P4752W and see yellow and bllue halos.

Have you tried to use the convergence function on the TV? If that has not fixed this issue then you have bad convergence IC chips. These chips are microprocessors that align the blue and red tubes with the green (which is stationary). This converges the three tubes to create the image that you see. Failure of these chips (usually from heat over time) is a common problem with projection  TVs. The chips are not very expensive; from $35-60 for the pair. Replacing them involves some tedious desoldering of the old ones and soldering in the new ones. If you have some experience with electronics and soldering it is not hard. Shops will charge $300 and up for this repair. If you want to do it your self post a comment bnack here and I can assist you further.

Samsung HC-P4752W 47" projection TV distortion & yellow?

I think you have a fault on the chroma board and on the picture frame board. If you can trace it yourself try these two locations otherwise call out a competant technician. hope this helps.

Samsung HC-P4752W 47 in. Rear Projection bigscreen TV

You dont have to remove the aluminum heat sink. The ICs are attached with screws and then just unsolder the ICs from the circuit board and then replace the new ics into the pin hole locations after applying heat sink compound onto the back then screww the new ICs to the heat sinks then solder the pins. Very easy repair.

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

You will need to replace or have the main convergence amp board replaced or have the main amp ICs replaced. i you have no electronic experience with printed circuit boards, play it safe and call in a pro to assist you with this repair. Good Luck

Sudden discoloration, ghosting, bowed horizontal lines in top and bottom of picture

The convergence ICs probably have a cracked solder joint on the foil side of the circuit board. Re-flowing the the solder would help. I will always replace the convergence ICs when doing this job. The labor remains the same and you will have to pay a few extra bucks for the parts. To fix this yourself, you will need to be able to identify the two convergence ICs, have a basic knowledge of electronics and be able to use a soldering iron. You will also have to do an alignment through the service menu.
