Samsung HLP5685W HDTV-Ready DLP Rear-Projection TV 2004

Was wondering if anybody can help me out here. I have had this tv for a little over 3 years without any problems. Two days ago, a dark but transparent band has appeared on the lower left side of the screen only. It tapers to very thin at the left middle of the screen, but it extends about 1 inch when measured from the bottom. You can see the picture through the line, but the color looks very funny at the transition point. Any ideas?? Thank you VERY much in advance. has a thread on the issue and says it is a defective mirror box. Samsung says it has not been an issue but dozens of others were able to get Samsung to fix out of warranty. HELP!

SOURCE: Dlp problem

The unit has a defective light tunnel contained within the light engine. This part is not easily replaced and you will a qualified tech to replace it. Many service centers condemn the light engine at a much hight cost. Do not buy or let someone tell you the light engine must be replaced. This repair requires only the light tunnel.

SOURCE: Picture shadow on rear projection Sony big screen TV

You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

SOURCE: White dots appearing on Samsung TV screen and multipling each day

It seems you might have an issue with the dmd board. Go to the menu, and if the dots still show on the menu, the issue definitely is with the dmd board but if they don't come up on the menu, the issue will be with the video board.

That was likely a capacitor that popped. Slight burning smell? You may need to have a technician come out to resolder a connection or two.

Watching tv funny noise like it blew up and turned off, bad burning smell ,now turn on tv starts to power up like normal and then nothing any help much appreciated, tv is a samsung HLP5685 56' inch rear...

The smell and sound are that of a capacitor burst. If you open the back cover you will find wax around a cylindrical object. That's it. Replace it with an exactly the same item.

If the white dot is on every picture and every input and stays there for a sec. after you press the power button to turn off the tv then suspect a stuck mirror in the DMD.

Samsung HLS5086W - spider crack on outer screen

The outer screen is called a Lenticular screen, it may come as a set with the Fresnel (the inner, and the way I would actually go) the screen is very hard to replace usually on a DLP as they have a somewhat sealed upper side and alot of screws.
