    wouldnt it be easier to replace the convergence board all together?

    Yeah, I have a 47" Samsung...it seems like the same problem. Green bending lines across the top, and some on the bottom. Makes it hard to see the top...Is this something I can fix myself? Or do I need to take it in?

    Thanks. brett@kiss1053.com

Elissa, unless you have some basic electronics experience probably not, what your describing is one of the most common projection tv problems there is, but it will require replacing a few components on a circuit board. You will need to solder and possibly check resistance values of a few resistors. I will say there is no need for a samsung servicer, any tv repair place will know how to repair this problem. Probably will cost around 300 if you have somebody to your home. I don't think your looking for the Technical details but if so replace the 2 large STK amplifiers probably (STK392-040) and test all resistors and fuses in input/output ckts, replace accordingly.

    I'm not sure on that model if the convergence amps are mounted on a small bd above the others then yes, if they are on the big deflection/HV bd below, it will be expensive and possibly difficult to find. But the short answer is yes, replacing a bd is always easier but a luxury TV Techs have learned to largely live without.

Where does the power cord hook up on the circuit board on my samsung hcn5527w?


The power cord normally goes through the Main switch and into the power supply section which is the SMPS. You will find the main fuse and the AC filters before it feeds to the rectifier section.

Samsung hcn5527w convergance factory reset


Sorry, I just saw this post.
I hope this helps.

Yes there is one more step. You should call the technician out and have them set up the Magic Focus adjustments. I have serviced these televisions for years and I have made this mistake and had to return to fix it. You should not have to pay for a rework. The technician should have done the complete job the first time.

I hope this helps
and good luck.

HCN5527W - Shot down burned i


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).

Michael,
the problem you are having is caused by bad convergance amplifiers along with open pico fuses internal to the set. these amps range from $45.00 to $65.00 each and both amps need to be replaced. this is a common problem with rear projection sets. these amps work very hard and are kept cool on large heat sinks. so with that a tech is needed to repair. techs may charge $150.00 to $350.00 for the labor. so shop around. as for the adjustments you made let the tech know because you may have set the settings far out of the range for the set and will cause shut down before it can be reset. the tech will know what to do. to find a factory athorized repair shop call samsung the number is in your manual or on line.
