Toshiba TV Keeps shutting itself Off.

If I unplug it and plug it back in, the TV works just fine for a few minutes and then shuts off for some reason. I even have it plugged directly into the wall. I I also made sure the timer mode is set to zero. Only 18 months old. Is it worth fixing? When the TV is on, it works beautiful. I bet it is something really simple and basic. Please Help. Thanks in advance. Richard O.

If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace If this does not correct the problem, you may need to have your TV serviced. good luck!

My Toshiba DLP Projection TV model number 44NHM84 will turn on but shuts off after 1-2 minutes. What do I need to do to fix this issue?

There are several reasons why your Toshiba DLP projection TV might be turning off after a few minutes. Here are some steps you can take to try and diagnose and fix the issue:
  1. Check the lamp: The most common reason for a DLP TV to shut off after a few minutes is a faulty lamp. Check the lamp to see if it's still functioning properly. If it appears to be damaged or has reached the end of its life (typically around 2000-3000 hours), replace it with a new one.
  2. Check for overheating: Overheating can also cause the TV to shut off. Check the fan to see if it's running properly and clean any dust or debris that may be blocking the airflow.
  3. Check for firmware updates: If the TV's firmware is outdated, it can cause it to shut off. Check the manufacturer's website for any available firmware updates and install them if necessary.
  4. Check the power supply: A faulty power supply can also cause the TV to shut off. Check the power supply unit to see if it's functioning properly and replace it if necessary.
  5. Check the color wheel: If the color wheel is damaged or not functioning properly, it can cause the TV to shut off. Check the color wheel for any damage or signs of wear and replace it if necessary.
If none of these steps solve the issue, it may be necessary to have a professional technician diagnose and repair the TV.

Tv cuts off and green light flashes

Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!
