This is a convergence problem that can be as simple as poor solder connections on the pins of the convergence ICs or defective ICs. If you can solder, you may be able to fix this yourself. If you wish to attempt the repair, update this and I'll provide additional details and instructions.

First locate the convergence ICs. These will be large black ICs attached to a heatsink and marked STKxxx. Try resoldering the pins first. If that fails to resolve the problem, replace the ICs. There may be other parts that need to be replaced as well, but start with the resoldering and/or replacing the ICs and update this with the results.

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.

Green out of alignment on samsung rear projection tv

Hi luke I am in the uk and not familiar with this set is it a three tubed crt television or an lcd projector type .. either way what you are descibing is convergence ( three primary colour guns all pointing at the same spot in a nutshell ) in the case of a crt projection tv three tubes one red one green one blue .. there should be a convergence pattern in the menu to re set the convergence via the remote check the manual . If it isn't adjustable you may have a scan coil fault or a tube ie : green with low emission check the green colour gun transistor and associated circuit for leaky caps resistors that have changed value or transistor leakage .. and don't forget the ever popular dry joints on the scan coil plugs .. hope this helps Vortash

Triple vison/WHAT IS AN ic?

If your colors will not line up on the television screen using the convergence menu, the most likely cause is that the convergence IC’s in the set are damaged and need to be replaced.

IC’s are just many small circuits built into one package, many diodes, transistors, resistors, even regulators and power supply circuits, they can be various shapes and sizes.

There are two and sometimes three very large IC’s that control the convergence in a big screen set. They are fastened to a large heat sink because they generate a good deal of heat. Finding these is not that hard, but there is supporting electronics that will also need to be replaced during the repair. There will be fusible resistors and feedback resistors that may have been damaged at the same time.

If you choose to repair the set yourself, be very careful of the high voltage that can be stored in the capacitors, and CRT’s. This voltage can be as high as 30,000 volts.

Unless you are very handy with a soldering iron and reading color codes on the resistors. I would recommend that you have a local television service center have a look at it and get an estimate for the repair.

I don’t use the cheapest parts when I repair this circuit, because I have seen the cheap IC’s damaged as soon as power is applied. I would also recommend that when the IC’s are replaced, whoever does it, that they use plenty of heat sink compound and remove the old compound first.

I guess you are wondering how much this repair would cost.
Not knowing the labor rate in your area and diagnostic fees, I can only give you a ball park figure. I have done this repair for between $375 and $450

I hope this information allows you to resolve this issue.

Blue CRT issues?

Yes the puddle is related to the Blue CRT coolant leaking. You are most likely going to need a new Blue CRT drive circuit board and quite possibly a new Blue CRT if the CRT got too hot from not haveing a sufficent supply of coolant. You can get replacement CRT drives and CRts at the following link.
