I'm sorry to hear that you're having this issue with your DLP TV.
Unfortunately, many of the service techs have one advantage over me - they can look inside your unit, and I'm unable to. I'm not sure if the noise is caused by a board, the color wheel or any number of variables.
When the light goes out, have you tried re-seating the lamp? If you pull it out and push it back in (after undoing the housing and the screw that connects the lamp to the engine), sometimes that helps reset the lamp and gets the unit working again. I can't explain a bout of bad lamps, although I would tend to agree that you're going through them at a relatively quick pace.
I'm not sure who the distributor is, but just like anything else, there can be cheap parts, and good parts, and then authorized parts. I have no idea which would be which. I do know that www.samsungparts.com sells the lamps that are authorized - I'm not sure if that helps or not, but that's one option.
Do you have any service ticket numbers from your service transactions? If so, please post them here. I'll see if I can have someone review the case. While I can't make any promises (since it did last the warranty period), I'll see if there's something that can be done - no harm in asking, anyway. Those service numbers would allow someone to access your records with Samsung.
Well, I am posting here because it seems these forums are moderated by people that know what their talking about, and frequented by others that seem to have similar problems...Please help!
The story so far:
I bought my Samsung HL56A650 DLP HDTV December of '08. This was a MAJOR purchase for me. I work 2 jobs full time and other odd jobs. My wife had the good heart to allow us to finance this mammoth knowing how much I would appreciate it.
The first sign of trouble...
January of '10 the tv makes a weird noise, I hear some kind of pop, it cycles on and off and makes some more God awful noises and then I get 3 blinking lights. I call Samsung and they tell me it sounds like the light bulb died. I thought it was terribly short-lived, but being one month out of warranty, I am S.O.L. and I call the distributor for a new bulb. The new bulb arrived and I allowed 48 hours out of the box and sitting before powering it up because I did not know what temperatures it had been exposed to and did not want to heat it up and have a problem with condensation or anything. Voila, it worked again! Not too happy, but what are you going to do, but hope this one lasts longer.
And then 4 months later...
The problem strikes again! I first call the distributor to tell them they must have sent me a bad bulb and they inform me that they only cover the bulb for 3 months. If I popped the bulb in the second that it arrived and played my tv from then until now, it should still be working!!! They direct me to Samsung saying it must be something else. So, I call Samsung and they assign me a technician to come out and repair, (still at my cost). The technician comes in, claims that the housing that the distributor sent me is not a samsung housing, changes the bulb, and hands me a bill. Now I am out the cost of 2 bulbs + labor and NO ONE is willing to admit they are wrong and reimburse me anything. Samsung claims it must have been a bad bulb. Distributor claims it is something else causing the problem.
60 days later...
Oh yes, didn't get very far on this bulb! Same problem. I cal Samsung, and now they say they'll renew my warranty and send a tech out at their cost. I tell them at this point we can agree it is not just a bulb right? And they claim they'll definitely send a tech out with more than just a bulb. I am unable to be home when the tech comes. He comes in, changes the bulb, and leaves. I am fuming! This time, the girl from Samsung says if it breaks again they'll give me a new tv, so I just let it drop after a few nasty phone calls.
And then it breaks again...
Guess what? The tv doesn't work AGAIN! Samsung says they can see that I was offered a new tv, but that girl was not allowed to offer such things and has since been let go. I say at least give me a different repair company, and there is none other in my area. At this point I have been to a bunch of forums and have read about countless similar problems. Samsung again extends my warranty. With this new-found knowledge I ask that the tech comes with a new ballast, color wheel, and power supply to which I have to wait an UNBELIEVABLE amount of time for him to procure and then set up an appointment. He comes, changes the bulb and tries to leave. I tell him no way is he leaving and that this is more than just a light bulb. I call Samsung and dance around their cs lines waiting for a representative. The guy finally ducks out, and I speak to someone there who tells me that if the tv is working, they can't send someone out til it breaks again.
And then again...
Yep, still burning through bulbs, though this one lasted longer than 60 days. I missed one other repair there, but I don't care to go back and figure out where. I am on bulb #6 at this point, with the same repair company coming. I am out about $500 on repairs from my own pocket plus days I had to take off from work to be there for the repairman. I am at my wit's end, but with so much time and money invested, I have no choice but to continue this dance. No one will take ownership. The distibutor claims there are no problems with the bulbs. Samsung will not replace the tv and accept that this is some kind of lemon. The repair company will do nothing more than swap the bulb and tell me they have "visually inspected" the rest of the components. Because the tv works with a new bulb, that must have been the problem.
So, I look to you all for advice. My tv exhibits the following problems:
It makes a low humming sound intermittenly
It obviously burns through bulbs like a teenager changes their underwear
When the bulb does die, I have a cycling of on and off and some whirring noise.
Any and all reasonable suggestions would be very much appreciated!
