I have a 61" Samsung DLP HLN617W. There was a ruckus which I thought was on the show and the picture went out. The Sound was there and I was able to change the channels and hear fine but no picture.

SOURCE: 61" Samsung DLP w/ no sound

my speakers died some time ago, it wasn't worth fixing, went to a component 5.1 speaker setup. good luck.

SOURCE: no picture but sound once it goes off there is 3 blinking lights

Most likely for this symptom is the lamp. If you'd like you could sit behind the set and have someone turn it on, you should hear the color wheel spin up and then you should hear the ballast try to fire the lamp, it makes a small arcing sound. If the lamp doesn't light the process starts over again.

When you replaced the color wheel it sounds like you took the DMD board out or you bumped it? Either way the DMD board will need to be realigned and that involves reaching into the TV while it is in normal operation. The DMD board in the one sitting right behind the digital bard and has a small fan facing the heat sink on it. There are three screws 2 on the left side on one on the lower right that need to be loosened just a bit and then with the set on you will have to move the board back and forth to achieve dead center. Remember from the back moving the board to the left moves the picture to the right and pushing down on that board will shift the picture upwards.
