The picture has lost focus and lost green


hard to say for sure, but the front opens up when you remove the bottom or edges. inside you need to inspect the CRT boards for any fluid leaks. there are focus adjustments on a black controller with 3 knobs on it. I would say take a look at the middle tube (green tube) if its dark and the circuit are dry. Try cleaning the CRT pins with the TV off, simply pull the cba/socket down and push it back up.
so lets see no green tube lite , cleaned pins no fluid, next tap it to see if it flashes bright, no OK now on the grn CRT circuit board slowly TV ON turn up the control you see and see if the green gets brighter. The CRTs are fluid filled and the fuild can get cloudy causing it to get dark and blury too. to check the fluid you would need to pull the screen off (a real pain)
these steps will help you isolate the isue and decide what to do next, hope this helps

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.

I need help!


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.

Samsung projection tv


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.
