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:
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.
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.
Check for firmware updates: If the TV's firmware is outdated, it can cause it to shut off.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.
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.
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.

hello
When the TV has been powered on long enough for the lamp unit to get hot, it may take several minutes for
the picture to appear on-screen. See "IMPORTANT NOTICE ABOUT HOT LAMP R
When the TV has been powered on long enough for the lamp unit to get hot, it may take several minutes for the picture to appear on-screen
in the following situations:
• When the Quick Restart™ feature is set to OFF and you turn the TV off and then on again within a few minutes.
• If the TV is on when a short-term power failure, power surge, or other similar power failure occurs, such that the TV loses and regains
power within a few minutes.
This is a property of DLP TV lamp technology and is NOT a sign of malfunction.
If this occurs, the green LED on the TV front panel will blink (and the red LED will be lit solid) until the TV is finished restarting the lamp
and the normal picture appears. If BOTH green and red LEDs are blinking at a one-second rate, you will need to turn the TV off and then
on again to restart the lamp.
ESTART" on page 8. if this no good check the lamp in side to see if it's not burn't out good luck
My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?
2 things will cause this Lamp is defective, or Fan to lamp quits running this will shut TV OFF, if the fan quits running while Lamp is on it is design to shut Lamp Off to prevent Damage to Lamp IF Fans are ok It will be the Ballast board It is what turns Lamp on.Look on E-Bay for Ballast board if it turns out thats what you need or call Encompasss Electronics 1-800-638-3328
It is possible the lamps may be defective or that they may be the wrong replacement for this model, as it may have a different wattage setup with the ballast. If you want to try to order the TB25 lamp from a different vendor, you can order the original Toshiba replacement lamp for this model (52HM84) from a major Toshiba parts distributor at the link below:
