Purchased my tv September of 2006. Five years later I check the lamp hours and it's only 2900. Though we don't use it like our bedroom set, only during football season and new blu-rays, thought the hours were much more than this. Was thinking it was time to change the bulb, but the PQ is still looking very good. I wanted to get a 3d tv to replace my 7178. After serious thinking and research, I'll just replace the one in my bedroom.

I need help with a fan replacement! Lost the link I had with good instructions/guide!!
Samsung HLS7178W
And I only see one " colling fan" spelt wrong on ebay for 32usd
seems like the right one but lost my bookmark i had when i replaced my bulb on how to replace lamp housing/fan
any help would be greatly appreciated
It's not color wheel as it stays on BUZZING after power off tv for 1-2 mins and you can see it spinning and when it finally stops
the sound stops

ALSO WONDERED there is more then 1 fan in this dlp but it seems like only 1 is making alot of noise
should/can we replace the other one that I can kind of see and is it easy?
Same fan?
Thanks going to research the forums and hopefully check back for some wicked info asap smile.gif
long time lurker didnt even have a login anymore wanted to post and ask so thanks again!!

seems like fan #1
looking at the back where inputs are
the right side behind the lamp is the noise
Press power on the tv and 30-45 seconds after lamp goes out it continues humming buzing then u can hear the click and power drains and u hear "it"slow down and stop the noise also

It has been months since I looked at this thread. This might be the thread you ask for (I did not test the link)

Fixed fan no 2 ! It is the fan behind the lamp so you need to slide that whole piece out
Soon as I replaced it and hard reset it booted and sounds amazing!
thanks to all

8yrs and still going.

1) Samsung replaced the light tunnel when the glue failed (early in its life 2007?)
2) that repair failed and they replaced the entire lightbox (2007/8?)
3) New lamp end of last year. Reset bulb count: 10k hours
4) Now I see a small black dot in the center. Where there's 1 there's prob 2.
5) In prep I bought a new DLP chip for ~$100.

Samsung #4719-001969 / Ti marking: 1910-6003W

If we deem the display has too many dots, we will do the DMD DLP replacement. Looks pretty straightforwards.

Not too many TV's that you can service these days quite so readily. We are still very satisfied with the TV. Movies look very good to us as LCD just looks a little too crisp and clean and there is something about having a bulb project the image, makes it look more like a movie theater experience to us.

Hope I am not the only one still enjoying the HLS7178!

Hello Morbos,

I too still enjoy my 7178 Sammy! It sounds like you know what you are doing in the repair department. I would love to run a couple of issues by you. If you dont mind assisting me getting to the bottom of these issues. Thank you in advance.
