Question about Samsung Televison & Video

4 Answers

The picture on my Samsung model #HLR4667WAX/XAA TV has been freezing up, then the screen would go black, now I can't get a picture and the lamp light keeps blinking on and off. Also, the TV will not allow me to change sources or adjust the volumn when this happens. As of today, the picture will not come on at all. Could this be a lamp problem or not?

    I appreciate your help, and suggestions, so thanks for the response. Not sure if it's worth having someone to look at it, and the cost involved on service calls, and or replacement parts, or if it's better to just replace the TV. It has been trouble free for the last 5 years, but since the cost of TV's have gone down, just not sure if it's worth fixing. Any suggestions on that? Again, I appreciate your time and suggestions.

  • alarosa001 Sep 17, 2010

    Thank you for your time, I really appreciate your help. I may look to see if I can get a repair man to come and look at it, that way I can decide if it's worth fixing or not. I also appreciate your suggestions on televisions should I decide to go that route and replace the television.



    Again, thanks for your help.

    Ginko, again I appreciate your response. Sorry for the late response this time, but I left for work after our previous contact, and just got home. I will contact Samsung and see about getting a repair man out to at least give me an estimate of what they think it will cost to fix, versus just buying a new TV. So thank you so much for your help. Don't want to take up any more of your time, and you definitely have been a help of helping me to decide what to do next. Have a great evening, and a good weekend.



    P.S. I do have another question, if you can help with another Samsung 42" that I bought 2 weeks after I bought the one that we're currently talking about. If you can't help, I understand, since I paid for help with the other one, but if you can, I do have a problem with my other Samsung as well. About 2 weeks ago some white spots starting showing up in the top right hand corner of the TV, and each day about a dozen new white spots show up. Now I have about 1/4 of the screen with these tiny white dots, and I have no idea what is causing this. Any suggestions, or should I be looking for possibly 2 new TV's?

    Thank you for the reply. So you think that I can just change the lamp and that will fix my problem? My concerns were the fact that the screen would freeze up, and that none of the TV controls would work. In my mind I did possibly think that if it is indeed the lamp, that the picture would simply just go out and not cause any freeze up of the picture. But then again, you are the expert, not me. If you think the lamp will fix the problem, then I will try that first. Thanks again for your help, and I'll be waiting for your reply.

    Thank you for the assistance, but I keep getting different feedback from different people, you are the 3rd one to write back. While I greatly appreciate everyone's information, I'm still kind of at a loss of whether the TV's are worth trying to fix or not. I've been told that the first problem could be either the lamps, or the ballast that is going out, and that it could range from approximately $150 for the lamps, up to maybe $500 or more for a ballast, it there aren't any other problems.



    The second TV I was told is not worth trying to fix since that will cost upwards of $800, so I may just write that one off. Do I try to change the bulb on the one that is freezing up, and hope that corrects the problem, or could that be a ballast which may not be worth replacing. Just trying to decide which way to go, so if you have any further suggestions, I would be interested in hearing them.



    Thank you!

Hi,

To begin with, lets remember the thumb rule - if the cost of the repair is more than half the amount of the actual product, it is better to go for the new one.Average life of these products are between 7 - 9 years. So, if you have already used it for 5 years - more often it would work for 2 - 3 years more. Spending $500 is absolutely not worth it in long run.

Now, Regarding lamp - there is no way to detect that. Once you spend around $150, then you would know the actual result. The other thing to be taken into consideration - Do you have electronic repair experience. Replacing lamp on Samsung models are a big pain. It is not as easy as it seems to be.It could be a faulty Lamp, bad capacitors on either ballast or power supply. Measure ballast input voltage 240 - 300 volts.If you have not replace the bulb in 5 years, then most probably it is lamp. Then it would be worth replacing lamp.There are certain places where you could buy the part and if that would not solve the problem, you could ship or return it .Obviously, you need to pay shipping or pay back charges.

Regarding the other TV, i would appreciate if you post another question.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Hi.

    Re:"Thank you for the assistance, but I keep getting different feedback from different people"

    Yep, and among different people you gave me a bad feedback, in this way I end up following your problem with ten comment, and you risk to pass the solution to someone that is just guessing "it is worth" or "it is not worth" to score the $2 miserable reward.

    Well, sorry about that , I guess next time I should dedicate less attention to the single problem.

    All the best.

Hi,
Your first TV that got freeze has problem with system control chip that is mounted on DMD board, now DMD board comes along with light engine that would cost you approx $300 plus labor so now you have an idea that repair could cost you $500 to $600

Your second tv got problem with DMD Chip that generates image in light engine and it would also cost you approx $300 plus labor.
Hope these info will help you to decide about repair both tvs.
Thanks.

This is certainly the problem of the lamp. Replacement of lamps will solve the problem.

Hi.

If problem was the lamp, then the TV would have simply gone to stand by , with the lamp indicator on. The TV staying on with lamp indicator,

Picture freezing, sudden and random loss of picture with TV not going into protect standby may be caused by a defective ballast (the board supplying power to lamp), but also main PSU and main Pcb controller may cause the same problem.

Since the condition is not reflecting any common fault, the TV must be tested to find out the problem. Replacing the lamp may fix the problem, but since the TV is not displaying standard replace-lamp conditions, there is no assurance that replacing lamp will fix the problem.

If lamp does not fix it, next part in line is ballast, but again, more parts may need testing.

Before buying parts I suggest calling Samsung at the number listed on the owners manual and asking a quote on repair.(see contact us - SAMSUNG )
Alternatively replace lamp, but some of the conditions described are not normal behaviour when lamp is simply over.

    Hi.

    Re:"Not sure if it's worth having someone to look at it, and the cost involved on service calls, and or parts, or if it's better to just replace the TV. It has been trouble
    free for the last 5 years, but since the cost of TV's have gone down,
    just not sure if it's worth fixing."

    the point is that the lamp is about $150. Replacing the lamp may fix the problem. Since lamp light is on, lamp is likely involved. However, since this is not standard behaviour, you may find out that after replacing the lamp you need to invert money in some other part (often the ballast, for example).

    The TV is in any case worth repairing. A new samsung DLP (rear projection) will cost over $1200. Cheaper DLP from other brands will not have same quality. The decision if you want to replace lamp first, accepting that there may be the chance that you have to fix something else later, or if you want to call the technician straight away. If the TV is several years old, then if lamp has not been replaced I suggest going for the lamp. This TVs have 6000 hours use, that goes in 3/4 family use years.

    If you have money to put into a new TV, and you rreally want to upgrade the TV I suggest passing to the flat panel technology. They give better quality, use less energy, and are less prone to failure.At the moment the top choices are probably between Samsung LED TVs, LG high frequency technology, and Sony. I suggest also buying extended 3 or 5 years warranty on next TV.

    Hi Tony.

    About the repair, unless you have your own repairman, try calling Samsung. They will put you in touch with an authorized repairman. They may also be able to tell you if there is an issue that we are not aware of with this particular model (eg. firmware), and if for that reason the lamp replacement warning is causing erratic behaviour. About the lamp, if you have not replace it yet, you are probably getting to the 6000 hours, then the lamp replacement is in any case do. If you want to save some money you can replace lamp first, and see if that works. Just be prepared in case there is some additional fault, in that case you will need to spend about $200/$300 extra or little more to test ballast and PSU and replace any part if faulty. If lamp sorts problem out you do not need any further repair being carried on this TV.

    Ave a good day.

    Hi.

    On rear projection TV random white spots in a delimited area are symptom of defective light engine. If problem is the light engine, then the TV is not worth repair. Light engine is a very expensive spare, usually at least $800.

    I see that I got bad feedback and that the question passed to different experts, well sorry, I was offline.

    I hope lamp will fix the first TV, if the second one has got light points randomly distributed, then it is the light engine. If instead you have an halo, then problem is color wheel, if you have a shadow, problem is mirror in light tunnel.

    Good luck.
