    If you’ve ever had Mitsubishi TV problems, then you know how frustrating it is. But, that doesn’t mean that it’s time to take your television to Goodwill or the dump.

    Blinking Green Light

    Many people with a rear projection Mitsubishi TV often experience what is commonly known as the “Blinking Green Light of Death". It’s known as this because it means that your television is about to die. But, even relatively new televisions can experience this problem, and Mitsubishi customer service doesn’t really know how to fix the problem.

    Many people, however, have had success by changing out their capacitors. Basically, you need to remove the four original capacitors and replace them with Radial Polarized capacitors. You may have to order these capacitors online if none of your local stores carry them. While this may not work, it’s worth a shot and a lot less expensive than purchasing a new television.

    Overheating TV

    Another issue that Mitsubishi TV owners have is that they’re television will overheat. This is really noticeable if have your television in a room that is already warm. The television will turn itself for a few hours, and then turn itself back on.

    The most common solution to this problem is that you have a fan that either is extremely dusty or not working. First, clean out your fan. Shut off the television and unplug it from the wall. Take a brush or a cloth and wipe off the fan.

    Next, turn the television back on, and let it run for a few hours. Then, stick your head behind your television and listen for your fan. If you don’t hear it, then your fan is probably broken. Order a replacement fan and change it out. You should probably not use your fan when the fan is not working. Overheating could cause permanent damage to your television.

    Stars on Your TV...and Not the Ones that You Want

    If you own a Mitsubishi HD TV, then you may have noticed little dots on your television. These dots are bright and are in various places around the television. This indicates that you have a problem with stuck micro mirrors. These mirrors are located on your DMD board, and there’s no real easy way to fix it.

    You will probably have to replace the DMD board if you are having this problem, which can be expensive and difficult to do. If you are having this issue, try taking your television to a certified Mitsubishi repair person. They may be able to fix the problem without replacing the board. If your television is still under warranty, take it back to the place where you bought it and ask for a replacement.
