    Can this board be component level repaired?

    I have the same problem. Somehow fixed it about a year ago, having it again. Have turned it off, then on again. I don't even see a spot on my remote for setting a timer.

    Certainly as long as you have a good quality digital ohms meter and a ESR meter which will test capacitors in circuit and then you would need a service manual so you could test the various low voltage and operating power supplies. Once you found the correct circuit that isnt up to specs then you would need to trouble shoot that circuit. But you will definately need those three items to trouble shoot that Circuit board as all the misc. power supplies are on that one board.

Samsung three colors on screen, out of focus #hcl4715w


It is a convergence problem. The IC's (integrated circuits) or STK chips or the "guns". You have a red,and blue, IC's that provide all the colors. When the colors are out of convergence, you get ghosting or what looks like 3D pictures. I haven't been able to locate the part numbers for the IC's or STK chips but have located a convergence board. No luck determining if IC's are included (a phone call first to verify) but if they are, would make life much easier for you to install. Part # is BP95-00415H http://jr.partsearch.com/Part/Samsung/Samsung/BP9500415H/New.aspx?ModelMfgName=Samsung&ModelBrandName=Samsung&ModelNumber=HCL4715W

Typically, IC's cost around $10 or less. here is a link to a guy who provides pretty good instructions on replacing the IC's along with pictures.

Flashing red lines on Samsung hcl4715w rear projection


The convergence board wont correct the problem. You need to replace the two Convergence ICs on the sub board STK392-040 and you will be back to normal. See my response above. That site will help you get it back to normal.

Samsung HCL4715W will not power on


At five years old, I doubt it will be worth replacing the power supply , a picture tube or two and possible the signal board. Cut your loses and get a new set.
