I have a 5 year old Samsung S5688W DLP and recently having the audio sounding slightly muffled/echoing. I have unplugged/re-plugged all cables and wondering if one of my children could have blown one of the internal speakers. I have gone through the manual but nothing covers this problem.

The color wheel or lamp ballast needs replaced...it would be hard to know which without being there to look at to fix the humming problem, neither part is that is that expensive if you price shop, you may want to try one at a time ot save money. Also to fix the picture you need to realigh the DMD board with the help of another person watching the picture.Hope this helps.

I did some reading on this. They said its caused by a faulty DMD board. I understand it's costly... around $700 to replace. Still looking for a cheaper avenue...

Hi, you have one of two problems, either the color wheel is going or one of the cooling fans are going, the color wheels are a very common problem in samsung dlp`s, sorry I can`t nail it to a specific part but I`d bet it`s the color wheel as they are notorious for failing in samsungs, video-tek
