Question about Samsung HCL4715W 47" Rear Projection Television

1 Answer

Projection tv I have a Samsung HCL4715W rear projection tv. Just recently we turned it on and it seems as though the green tude has shifted a few inches to the right. The focus is fine, it's just that the one tube may have shifted. The auto focusing doesn't work, it doesn't go past the green part.

Re: projection tv

A lot of times when the convergence ICs blow, there are also problems with resistors on the board (talking from Hitachi experience), or the board itself.

If the other problems, like blown resistors, are not repaired, the ICs will blow again right away. If the ICs are your only problem, then replacing them may work

the HCL473W, HCP4752 are basically the same set same features. The HCL models like the HCP are rear projection. Unfortunately Samsung no longer manufactures the rear projection CRT models they are only available in the DLP rear projection with the closest comparable model currently available for a new replacement would be the HL50A65 which is a 50 Inch 1080P suggested retail 1299.00 If I can help you further please let me know. Also new replacement chassis are available for the HCL4715W.
