Samsung DLP Problems
Wednesday, March 5th, 2008 @ 11:43 am
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 read that several Samsungs have an issue where if the bulb gets too hot, the plastic on the back of the TV actually expands and causes the rear lamp door to be loose which may trigger the safety switch that turns off the TV if it detects the lamp door is open. That may be why when you remove the bulb and replace it and re-tighten the screw on the door your TV works.

Sounds like it could be the color wheel…the ballast will not start the lamp if the colorwheel has failed. You could be jaring a stuck color wheel enough to free it up when you are messing with the lamp.

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.

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.

I have a Samsung 50″ DLP HDTV - Purchased from Ultimate Electronics 10/2003 - What a pile of crap this TV is. Within a few months the color wheel started whining, then 3 flashing lights on the front panel. Could only be reset by unpluging. Warranty tech said the color engine and “main frame” had to be replaced. 3 weeks down time.
failure #2 9/2004 same problem as above. Tech didn’t even bother to come out, said it sounds like the same problem as the first time, ordered the same parts. Only took two months to get it repaired WooHoo!
failure #3 9/2006 - intermittent probelm: without warning the picture would “bounce” or “jump” then the TV would fail. 3 flashing lights again. Now Warrantec was handling the warranty. TV picked up 9/11/06, returned 12/6/06 just a week shy of 3 months this time!! Repair co, stated they recommened replacing the TV called it a Lemon. but warrantec rejected that (of course), replaced analog board and few other things.
Failure #4 worked fine up until last week Aug 1st 2008. Picture distorts and jumps without much warning, alomost like last failure #3, has a slight cropping of the picture at lower left side of screen. Fails 3 flashing lights again. Scheduled for pick up tomorrow.
Warranty runs out in Oct. 2008 just over two months from now, probably before I get the TV back again.
Been down for repairs/in the shop for nearly 6 months within the last 5 years. I’m sure I have little to no recourse with Samsung, but I’ll write a letter to them anyway.
Next one won’t be a DLP, or anything by Samsung. I have LCD’s and Plasmas in other rooms, albeit not 5 years old, but in 2 and 3 years of use, not one issue what so ever.
Anyone else having simular problem with DLP’s? They are garbage as far as I’m concerned. But in 03′ the prices for 50″ plasma or LCD were quite bit more that the DLP.
Anyway, this is one worn out warranty. They’ll be glad when Oct passes.

We have a Samsung HLR5067W that is 2 1/2 years old. The picture started bouncing/flickering periodically. Occasionally get a “No or weak signal” error. Comcast has checked the signal and providetd a new HD box. The lamp popped so we just installed a new lamp. The problem is still there but now the picture actually goes black for a few seconds. We have no flashing lights on the front.
Any suggestions?
Thanks

Hi: We have a Samsung DLP (56″) that we bought in 2005. It worked great so far. Today, we hear loud buzzing noise and colors distorting on the screen. Can any one guess if it is a color wgeel issue or the lamp. Thanks!

I have a Samsung dlp 46″ TV. The light bulb is on and I get no picture. Seems very bright. When I look at the button on the TV in front all that it says is timer flashes along with lamp flashes and then after a while the TV shuts itself off. Would this be the bulb? The color wheel is spinning.

I was just watching and there was a loud POP and the screen went black. Unplugged the set and let it set for an hour. Fired it back up and everything looked as if it was going to be okay…but the screen never came back up. I’m guessing the lamp. Anybody else have an idea?
