Question about Samsung HCN5527W 55" Rear Projection Television

1 Answer

I need help!

Hello, I just found this site and hopefully I will get some help. In October of 2003 I received a Samsung HCN5527W 55" Rear Projection TV from my Grandfather, he bought it at Sears after reading several glowing reviews on the set. I'm disabled and confined to the home much of the time so unfortunately I probably watch more TV than the average American. It has performed very well over the years until about a month ago. Pretty much what I have read in others topics from owners of this same set, red bowed lines across the screen and "Perfect Focus" cancels itself after a few seconds. I think I may have made a mistake by trying to adjust it manually and it is much worse now.

So my questions are,
Can anyone refer me to an honest and qualified tech, or advise me how to find one please? I live in St. Joseph, MO. 64501
Did I do more harm trying to adjust it manually?
Is it harmful to keep using it with the red lines until I get it fixed?
It cost almost $2,000 in 2003, should I just get a new TV and if so what is the most reliable type or brand?
The only place open today said it was $150 just for them to come to my apartment! Very tough for a disabled man with only Social Security as income.

Thank you everyone for any help you may have.
God bless you and Happy New Year!

Sincerely,
Michael Curley

    Bob, thank you very much for your response to my questions.

    Bob,

    Thank you for the advice, I truly appreciate it. I just had a tech come out and check the set, when we spoke on the phone he said the same thing you did that the STK Amps might be bad so I felt good about getting it fixed for an affordable price.

    The good feeling was gone an hour later when he cane and tested the set and told me that the STK Amps appear to be fine but instead my "RED CRT YOKE" or "Digital Convergence Board" were bad. The repair would cost $600!!!! He charged me $70 for the service call but will deduct it from the repair if I have it done.



    Should I invest $600 in this $2000 TV bought in October of 03? Or should I just go find a new TV in the $600 range?



    What is the most reliable type of TV? The conventional old school type? The Flat Panels? Projection?

    How about the brand? Which has the least problems?



    Thanks again,

    Michael C.

    Bob,



    Does the "RED CRT YOKE" or "Digital Convergence Board" diagnosis sound logical or is it possible that I'm being taken advantage of?

    I'm just not sure it's smart to spend $600 to repair this 5 year old TV when I can buy a new 52" RCA for $750 at Wal-Mart. But if I do buy a new TV I doubt it would be a projection type after this experience.



    Are the Flat Panel LCD TV's reliable? What type of TV do you use at your home?



    Thanks again,

    Michael C.

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.

    You might have a hard time finding a 55" television for $600.00 but to answer your question about different tvs and there reliablity is very hard. All electronics will have some problems of some kind. but each one may have common problems to the style set. for instance projection tvs have convergance issues not to mention they have CRTs that dim over time or Horizontal output transistors that fail.

    other types of projection sets such as DLP,LCD, and LCOS have lamp failure (normal, since when have you seen a light bulb last for more that 10yrs.) or light engine failure (not as common but does happen).

    panels both plasma and LCD have problems also (nothing is prefect). in all cases buy the extended warranty you may never need it but should you, you will be glad you did (board level repair, costly).

    as for best brands look at consumer reports they have researched that stuff for you.

    which one is right for you? ask your self these questions.

    how do i use my tv?

    movies.... choose a tv with the highest contrast ratio.10K:1 or higher go with plasma, DLP or CRT. LCD will disappiont you with movies that have dark sceenes.

    sports..... brighter sets will do LCD,DLP,or any style will do in this case

    news and standard tv ..... choose any set.

    what size?

    what price?

    go from there for choosing your set

    The red yolk is possible but is not real likely to be the problem. In the years I've been doing this yolks are directly connected to the stk amps and would blow them if short. an open yolk would be uneffcted by the amps. digital conv moduals do go they have several op amps to control the stk amps.

    as for the RCA, stay as far away from any Thompson consumer product (RCA, GE, and Proscan). consumer reports has them at the bottom of the list and is in my experance not worth the trouble.

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.

In what way is the color off? Does it appear like a 3D movie? If so, the convergence circuit has a problem. This could be as simple as a bad solder joint on the convergence ICs or defective ICs. If you can solder, you can fix this yourself. Figure on $40-$60 for parts plus the local labor rate if you need a service center, just the parts cost if you fix it yourself.

Update this if you need further repair details.

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.

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.
