I have a 6 year old Magnavox 50 in DLP tv, model # 50ML8105D/17. When you power it on, the green light first comes on then after a minute, changes to two red lights, and the red light on the left sometimes flashes anywhere from 13-20 times. The picture never comes on, any idea on how to fix it or whether its worth trying? Thanks for your help

Your bulb is burned out. I have had the same problem. It seems this television has an overheating problem--and short bulb life. I have had our 50 Magnavox dlp for two years and just put in the second bulb before Christmas. You can buy the bulb from a dealer on ebay for $99 and install it yourself. I is not in the housing so you have to carefully take out 4 screws and replace the bulb without touching the face of the bulb. To buy the one from Magnavox with the housing is much more expensive. I think the first time my husband replaced the bulb it took about 45 minutes--this time it took about 20.

Pull the front cover off at the bottom. You will see a panel which has to be removed using a screw driver. Inside you will see the lamp assembly. It is a removable box. The lamp can be changed out by just changing out the connections on the new lamp. Before you pull it though try reducing your picture size to 4:3 it helped us to get a little more life out of our lamp.

If the picture has gone darker and kind of "foggy" the likely cause is that the cooling fluid in one or more of the picture tubes has become discolored. The only way to check for sure is by looking directly at the face of the CRTs (front or back cover/screen removal). Have a service call done and ask how much they charge to check this. The fluid can be changed but it's abig job (usually $300-400)

If this happened suddenly and the red and green images are bowed in at the center of the top, bottom and both sides, one of the convergence amplifier IC's has failed. The part number is STK392-120. Make sure it is a genuine Sanyo brand replacement; there are a number of cheap imitations out there that do not last. Generally they cost less than $30 each.

Note: there are two of these in each TV. They are notorious for having a high failure rate, so I usually replace both. (FYI: each chip has three amplifiers. Each color gets two amplifiers, so one color uses an amplifier on each chip. That's why we usually see at least two colors go out of whack when this problem happens.)

I assume you have already tried a different video source (DVD, VCR, etc.) to rule out input signal defects. If the problem arose right after the set was moved, either the optical alignment was disturbed or (less likely) there is a stray magnetic field near the set that is causing problems (magnetron from a microwave oven?). There is a procedure (sometimes provided in the owner's manual) for adjusting convergence using the remote control that can fix minor alignment problems. If you want to gamble it is not a hardware failure, try it first along one edge of the picture.

If you cannot shift the red or green dots in the convergence pattern, stop immediately, and make a note of where and in what direction you tried to move the dots. Inability to converge the dots is a strong indication the convergence amplifiers are bad (that is their job - to keep the colors lined up with each other). You will need to undo any adjustment attempts after you replace the convergence chips and any fuses or resistors that got burned when they went out, so don't make too much extra work for yourself or your service tech.

It sounds like you have a bad color wheel. If you are handy with electronics, it is a pretty simple fix. If not, I would suggest you take your set to a qualified service center.
