Samsung HLN617W auto shut off.

by freshbadboy / October 13, 2010 5:36 AM PDT


I have a Samsung HLN617W DLP TV that started to automatically shut off on its own. When that happens, the 3 led lights timer/lamp/temp show solid green/green/red and stay that way. I cannot then turn the TV back on.

Of note too is that when it turns off, and the leds are on, the fans in the back are actually working and some small green led inside is also on.

I have been able in the past to unplug the TV from the AC outlet and plug it into a different outlet to resolve, but last night, even that didn't work until I tried it many times (over 6 or 7 times into different AC outlets). When that didin't work last night, and I unplugged it it obviously turned off everything, but then plugging the TV to the AC outlet only brought back the same symptoms (leds and fan in the back without being able to turn the TV on).

The lamp is about 1 year old.

I have not tried the following yet, but wanted to know if this is something common:
- clean dust inside, but it looks clean anyhow.
- remove the lamp and reinstall it.
- open the lamp door and close it to make sure the sensor is fine.

Any help will be greatly appreciated.

Thanks in advance.

I forgot to mention that this problem is intermittent. I have watched for days and on some days 6 hours straight without issues, and sometimes/somedays it just happens.

Your option of...

- remove the lamp and reinstall it. the direction I would recommend. Often times, reseating the lamp is the simple and effective fix. If it doesn't solve the issue, it's likely something that is going to require an inspection by a technician.

Oh well, no such luck Sad

I did it once yesterday (reseating the lamp) and the tv turned off, then I did it again and the tv worked for a couple of hours, then I went to bed. This morning it worked for a few more hours, and shut off after that Sad

I called a Samsung repairman around my area, and he said that it is most likely the dmd board with will cost a lot to fix Sad

Any advice? How much do these boards cost? Where can I buy them from? Will I be able to fix it myself?

I am really disappointed. I just bought this tv second hand and was very happy with everything till this happened Sad

Sorry to hear that it didn't work. My remedy for these issues is the lamp reseat. If it's not that, I don't really have much to offer. The only other possibility is that the blue kill-switch on the lamp door - maybe move it to see if that's the issue.

I don't have prices for parts and labor - the technician would be able to give you a better idea on that.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
