Question about Samsung HL-R5678W 56" Television
I am getting a shadow about 2 in wide running down the left side of my tv. i was told my a samsung tech that i don't need to replace the entire light engine, but just a small, sheaper part called the light tunnel. any service repair centers around me have no idea what i'm talking about. i'm looking for some instructions on how to do it myself.
Hi, if you did not get help until now, i can send you step by step instructions and photos how to do it. I did several of these and it is not a big deal.But you will have to take apart a very sensitive optical device and if you are not confident that you can do it do not start this.bp67-00291a is the part number for the light tunnel.post a message here if you need that file with instructions

Old post i know but may help someone out
I have solved my problem of a dark shadow on the left hand side of my
samsung DLP sp4sl6hv using this video which was near enough the same as my set. When i could see the light tunnel i used a toothpic to push the mirror on the right back in place (it was a fraction of a millimetre btw) and all is well now. I also used this video for removing the whole light chamber as there are some wires to remove before removal, hope this helps in some way, costless fix to

Alin can you post instructions. The video Andy mentions is marked private and I am experiencing the issue too.
Thank you in advance,

Never replaced a Light Tunnel Myself, I have heard of this problem, Toshibas have done this to me as well, it is MUCH easier to replace Light engine and results in better repair, once you start taking a microdisplay engine apart you run the risk of contamination.
