You have 2 fans one fans the Lamp other Fans the DMD module, you may just have a bad Fan! Fans must be running in order for TV to Come on.Yes remove back .

Normally we replace the fan because it can't run at the correct speed and the Micro detects that, then sends the error to the screen for you to see.

Samsung Consumer LCD tv's do not have fans except on the higher end models. The Commercial models do. Yours is a Consumer model. I suspect that you have a DLP tv. In that case replace the Lamp Fan. It is the Larger of the three fans. With the rear cover off, you will see a Blue switch lever on the lower right side of the tv. Hold it in a up position and turn "on" the set with your tv remote. Then look for any fan that is not running. Then order that fan. there is a large fan that cools the Lamp. The other fans are of the same smaller size and one cools the DND chip and the other cools the Ballast.

the fan may be ok it may be another component thats caused the problem? if you have a meter check the fan you can also get intouch with the manufactuer they will try and help you

fan # 2 is having problems; maybe missing voltage or broken fan
good luck
