Our converange board tested bad. Replaced the new one, and turned TV on smelled something burning. Now cannot get the blue to move and the colors are out of wack. Just wondering why our TV was bought in the middle of 2003-warranty is up and paid $1.999.00.
Thank you Carol Strempler 262-878-4530 email@example.com

Re: Samsung TV model HCN5527W
The actual Convergence amp ICs not located on the convergence board are probaly what killed the origional convergence module, and likewise has killed the new board. You will need to change the convergence ICs first then replace the convergence module.
I would recommend getting the service manual . I can post a link if you would like.

The model indicated does not have a "bulb" as it uses 3 picture tubes.
Examine the picture with color set at zero---stand back and look= if the screen has a mostly yellow (all or part of the screen) you have bad Glycol in the blue picture tube(if need explanation ask) and a look in the lens of the Blue tube will confirm this.
If able with back off and a small mirror look in each lens--red picture, green picture and blue picture.
If the Blue looks like a floodlight with little or no image--bad glycol in that tube.
You have failed convergence IC's, Have the convergence IC's replaced on the convergence board, Replace them both they are the Large Black IC's mounted on large heatsinks usually mounted on a seperate board above the bottom main boards, The Part # for the IC's are STK-392-040
OMG! Dude, your screen is just plain fried. You don't need a new screen though, You just need a new bulb for it. See, behind the screen is a light bulb (unless your T.V. is plasma screen), sometimes two or three, and that burning smell was the bulb blowing (like when you need to replace a light bulb in a lamp or something). I don't know where you can find a new bulb, but once you replace it everything should be fine.
Your convergence ICs are defective and quite possibly the burning smell was likely some of the convergence Resistors burning. Its actually not that exspensive of a repair. you can get a brand new Sub deflection board for your set for 232.00 at the following link and that will fix your set and you just put the new board in. The site will also provide you with free on line tech support to assist you with installing the new board. you need the P54 Sub deflection board. Its available at the following link. http://servicemanuals.vstore.ca/
more than likely the flyback transformer has failed and also the horizontal output transistor as well. it is hard to say without looking at the set if you are not a tech then you will need one. these sets are very complicated and the novice going into them risk severe shock or death (30,000 volts).
The STK392-040 Is Convergence correction circuit! but the question is... what is the result when he replace the said parts? ok lets see... the probs. of your TV is a small parts like capacitor maybe this capacitor has change of value thats why the convergence is not in align...
Your TV set just blew out whats called the convergence IC's. These, both (2 IC's) will need to be replaced, and since you smelled something burning, there are most likely bad resistors as well on this board. You will need also a service manual for sure to do touch-up convergence alighnments. If you do not have any electronic serviceing experieng or any knoledge on repairing printed circuit boards, Play it safe and call in a pro to assist you with this repair. Safety is Number one on the list! Good Luck
