I purchased a Samsung DLP HLR5678WX in April of ‘06. About a year later the TV failed to operate and the indicator lights on the front of the tv indicated that the lamp was bad. Luckily I had purchased the extended warranty and only had to wait 5 weeks for my new lamp to arrive, yes I said 5 weeks. I replaced the lamp and the the TV worked great for 2 weeks and then blinking lights on the front of the TV indicating, yet again, a bad lamp. Only waited 3 weeks this time for a new lamp, I complained a little about the first wait. Replaced the lamp for the third time and it worked great for a couple of more weeks and then indicator lights again! I then went in and took a look around and removed the bulb and re-inserted it and the TV worked! It continued to work for a couple of days, indicator lights again. Removed the lamp re-inserted the lamp tightened the screw, the set works. This worked for a couple of months but the last time I tried this it didn’t work. I then called Samsung and arranged for a certified tech to come and check out my set, after all you shouldn’t have to get out a screwdriver everytime you want to watch tv right? The tech showed up and said that he thought it was the ballast so he replaced the ballast and the tv worked great for 3 days but then the same problem.

I am now begining to think that I have 2 spare bulbs and an extra ballast (yes I saved them) and that the problem lies somewhere else. Possibly the switch for the lamp cover? All connectors on the back seem to be in place. Is there a way to test the switch to see if that’s the problem? Any other ideas? Thanks in advance.

I have the exact same problem with a HLR-6178. After replacing what I thought was a bad bulb, the new one worked for a couple months but now I have to remove and re-insert the bulb to get the set to work. It will work fine until the set is turned off, then it will not come back on until you remove and re-insert the lamp again. Very frustrating and no extended warranty. If anyone has a clue as to what the cause or solution is to this problem, I’d love to hear about it.

That sure is a strange problem. The color wheel theory may be valid, but he’d have to have some funky picture or screeching noise, or any kind of winding noise if the color wheel was bad.

I’ve not heard that the plastic expands because the TV gets really hot, but anything is possible I suppose. The easy fix for that is to tape that door sensor shut. This is good practice just to check if the lamp is coming on while the back cover is open.

Samsung DLP 52″ is doing the same thing that joe’s and ray’s was doing. Picture freezes and then goes black. Does not allow you to turn tv off or switch to another source while it is turned black or frozen. I unplug it for a while and then it works fine for a while. ( A day or two at the most). Have a pc hooked up to it and it works fine, even while it is freezing up on component or hdmi (have satellite on comp. 2 and ps3 on hdmi comp.) I find that very odd. Please someone help me figure out what’s going on.

My screen freezes on my Sammy HLN5065WX/XAA. The color is good and there is no noise. I replaced the color wheel an year earlier and had no issues since then. I’ve want to check the bulb life but I don’t have a service manual in how to get access to the service menu. I’ve seen comments on other blogs on how to do so but my remote has n o INFO button. The remote model is BP59-00016. 1) What may be the cause of the freeze screen issue?; 2) How do I get acces to the service menu to reset or check bulb hours?

There is a solution to the Samsung DLP "white dot" problem, although Samsung denies one exists, I have found HUNDREDS of customers with the same problem.
Refer to this site, is has product codes to buy a new DLP chip and install instructions.

I urge everyone to write Samsung customer serivce and complain. There is talk on the net about a class action suit against them for this (though sadly I am Canadian and can not join).

I hope this helps everyone, I'm posting this link where ever I can.
