It's probably telling you that your bulb is nearing the end of its life. (At least it's doing its job -- half the time these things give you no warning at all.) So buy a replacement bulb for the day when the old one dies. You can turn off the annoying light by going into your set's menu and telling it you've just replaced the bulb. Be sure to do that again when the bulb actually dies and you replace it, so it doesn't give you a very early warning next time.

the bearings of the color wheel could be worn. the screws hold it in place, & there is a plug-in wire connected to it. for part# contact: http://support.toshiba.com/

The color wheel is not behind the screen, it in the optical engine. Most likely thats your issue.

Some possible reasons include: New lamp is generic and or has a issue----excessive dust or dirt inside the unit on fans etc.Some of these units had a feature in the menu for quick on where lamp is lit at low level all the time---this shortens the life of the lamp etcIf you did not have this issue before lamp replaced I would suspect a generic cheap bulb may have been used instead of the Toshiba cartridge / lamp combo which costs more.With the quick on if the set has it normal time is 20 seconds for screen to light----set WILL DETECT IF LAMP IS NOT COMING UP FAST ENOUGH OR BRIGHT ENOUGH.Generic lamps (cheap) will never be as bright or last a long as a OEM lamp unit.Just some thoughts based on your question.

check any SAP settings in the menu

I have similar problem with my Toshiba and I was wonder if you ever were able to get a solution. Pls advise?

Seems to be a thermal related case , it can be a semiconductor failure or a common thermal runaway due to faulty capcitors. Check for unusual heat in any circuit which can give a lead to probe.There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance. The best way to check for loose connections is to tap lightly when the set is powered on, if there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, and use a good soldering iron to solder all suspected points. Sometimes the fault occurs when the set warms up; if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault. It can also be related to WEAK ELECTROLYTIC capacitors as the value can reduce in time.
