The lamp ballast which ignites the lamp has failed it sounds like. The red flashing lamp is the tell tale sign with a good lamp installed. Make sure the lamp door is closed too, there is a door switch that can also trigger the red lamp and no startup. There is a company in San Diego CA that can repair the unit called PROJECTOR DOCTOR

This is what Tishiba indicates in the manual for your problem:

Lamp went out during use, or won’t come on
→ Returns to standby after about 2 minutes. If the projector fails to
operate normally after turning the power back on, either the lamp
needs replacing, or there is a problem with the projector.
• If a lamp burns out, replace it with a new one.
• Unplug the power cord, and contact your dealer.

Obviously you are at the contact your dealer part which isn't really a good situation since you are in Brazil. Researching parts will get back to you when I find something.

The reason why the projector is shutting off is so the lamp doesn't explode. It's more of a safety feature on the projector, you can reset the lamp and it might work for another 500hours. If the picture is still pretty bright I can get you the reset procedure, but be warn that when the lamp does eventually blow it could shatter the glass inside, so be careful, it shouldn't hurt the unit.

SOURCE: Toshiba Lamp Reset - How?

Not positive, but I would assume the same as my Toshiba.
With the on, input, and menu buttons held down, insert the power cable.
Hope this helps, NGK

How to reset lamp hours & total time toshiba projector TDP-T95

Supposedly the lamp has a chip that keeps track of the used time. The manual says to check in the instructions that came with the lamp. Others say that LG will not reveal how to do it. Perhaps you could ring LG service and give them your machine serial number and request that as the owner you want the correct information.

What is wrong with my tlp s10 it gives the entire picture a blue tint the lamp has done 2700 do I need a new bulb

Check the Video cable that feeds the projector, could be a broken cable or a pin bent -worst case the connector on the projector has broken.
Try the VGA cable on your computer screen.
The lamp does not need replaceing, the lamp emmits white light only.

What bulb is needed to replace in the projector?

three green lights come on then the standby light goes red and remains on when the projector is plugged in. The lamp and fan do not come on when the power button is pressed instead the lamp light comes on red.
