I ordered a new bulb ( Philips original ) for my Samsung HLP6163W. Put new bulb in today but noticed that the silver housing that attaches to the terminal was loose. spoke to technician at Discount Merchants and they told me that is a common problem on the bulbs and should not cause any problems. So I put the bulb in and nothing. Technician tells me that I need to reset the Samsung DLP TV’s lamp hour meter or hour counter. So i follow the instructions and actually see the screen show up. Since the instructions didn't say much more, I wasn't sure what to do next. I left the room for like 5 minutes and when I returned, the screen was black. I tried to recreate the menu screen but all I get is the Bulb light flashing in front of the unit. I unplugged the TV and tried again and then I get all three lights flashing. ( In the manual that it says that this means the bulb needs to be replaced ) Is the bulb not working because the outside terminal is loose from the housing or is there another problem.

Not sure hat to do next. any help is appreciated.

Oh no!

Call David at DM, he's a good rep there and he should be able to handle it. Tell him Eddie from Fixyourdlp.com sent you. There might be a problem with the lamp, but he can trouble shoot better over the phone than I can.

If you still have your old lamp, I'd advise trying that one to see if it still works too. The problem could be something with your TV primarily and putting in a new lamp really didn't solve anything. There could be ballast or color wheel problems--or the lamp door switch could be faulty. You've got to check everything--but like I said, if you cal DM and ask for David, he's the supervisor there, I'm sure he can help you out.. (800) 281-8860

Thanks Eddie. I will try my old bulb and I also have a friend that ha the same TV, so I'm going to take my new bulb over there and see if it works in his TV. I'll give David a call if none of that worsk.

thanks for the reply.

Eddie,

Okay, its not the bulb. I took it over to my friends house and it worked just fine. so how do you suggest i troubleshoot from here. I couldn't get a hold of David at DM, so they guy I spoke to is thinking its the color wheel. I don't want to just keep assuming its this or that and replacing parts. any thoughts?

Can someone explain the "reset timer" as I have not heard of his yet. For six months now I have been trying to resolve my issue of:
-Replace lamp
-Replace color wheel
-Replace ballast
-Set worked for about 2 weeks then screen went black and lamp apparently does not illuminate.

I even paid an on-line service to spend over an hour diagnosing the problem and he determined that it was a power source issue. This in spite of my reading 330vdc to the ballast. My question to him was, what reading should I be getting on the output side of the ballast going to the lamp. I have also asked this question on this forum and no one has been able to answer.

Can anyone help with this information.

Thanks, RB.

The lamp timer is a small program that keeps track of the hours that the lamp is in use.
Some time the tv wont turn on after replacing the lamp because the DMD detects that the lamp hours exceeds the limit. So for security measures it doesn’t allow the tv to turn on.

How ever there may be other issues, like did you close the lamp door? You see there is a small switch that if not pressed is will send a signal to the DMD, thus not allowing the tv to turn on.

Also there is the thermostat, here is the link to that post.

And last but not least, have you cleaned the inside of the tv free of dust and mold?
Good luck.

Thanks so much for responding to my dilema. Yes the switch is taped as you suggested a few threads ago. I have purchased a second ballast just to try to eliminate that issue. I get the same response with no lamp lighting. Incidently, the output voltage to he lamp is a mere 7.86vdc as measured directly into the lamp receiving sockets on the ballast. I got his reading on both my new ballasts.

As I have replaced the lamp, color wheel (which was shattered) and the ballast and still have no lamp on and can't really reset the lamp timer with no functioning lamp to light the screen, I will proceed in a different direction with the thermo-switch.

Thanks for the links and I'll let you know. RB.

My switch is not connected after my repair so I assume after reading the above, that's why it won't power up. Is there some work around? It looks like the wire clip was soldered on and now it can't be reconnected. So, if that's it can it be resoldered. I hate to have to order a switch, as I just got the part I ordered last Friday! Can someone help please?

Hello dallaswinn.
In theory yes, the connector can be resoldered, you see the sensor just sends a signal (a 5v I believe) to the DMD board, just one question, is the actual switch damaged in any way? If yes, then you would need to buy a new one.
Here is a link so you can get an idea of what to look for.

if you have any other questions feel free to ask.

[dallaswinn]

Eureka!!!!!!! Got the switch wires soldered back on, installed the switch and the tv works!!!! Yeah. . . . . One more question though. There was a small fan inside and a larger one in the back of the tv near the lamp. I've never noticed before but is the larger one at the lamp supposed to just come on when it's hot or run all the time? When I was putting all the screws back in and the tv was on, I noticed the larger fan was not running. Hopefully, that's not another problem????

[ChubbsTech]

Hello Dallaswinn.
That fan inside of another fan sound strange, anyway it’s probably nothing, since all the fans have a sensor that relay a signal to the DMD board. If at least one where to not function properly or fail completely the DMD would shut the TV off. So I think you ok.

[dallaswinn]

I didn't explain it very good. . . it's not a fan inside a fan. There are 2 fans inside the tv. A small one circulates air on the dmd board and the larger one I am referring to is at the back of the tv, circulating air around the lamp/color wheel area. That one is not on. Is it supposed to be running all the time or does it come on if tv gets too hot. I'm trying to determine if its working or not??

[dallaswinn]

Okay, tv is gone again; indicates bulb. I've been trying to get some answers to questions in above posts. . . obviously fan is not working. . . any ideas???

[dallaswinn]

Update on above post. Left tv off for a couple hours and tried it again. Comes on and has picture. . . I'm thinking the fan is the issue; obviously it should be running. Anyone have any ideas other than taking it apart again and replacing the fan. . . man this is getting old; and expensive. I'm thinking a new tv would be cheaper now.

[ChubbsTech]

Hello again dallaswinn.
I’m sorry to say this but you’re going to have to replace the fan, as mention before, if you have a malfunctioning fan its reason enough for the TV to shut itself off. There is no other way around it. The good news is that they’re cheap and easy to install.
I did a search on the sponsor of the site D-M.com and found this result.
