Why would the TCC2700 keep blowing fuses?

There is a short circuit in the power supply, probably caused by bad diodes and possibly a capacitor. The casing needs to be taken apart to see if a repair is possible.

Thank you for your query

This is a common problem in several projectors, I would recommned that you remove the lamp and then replace it, and the projector may stop the warning light

The other thing to remember as well is that some lamps can have manufaturing defects and so in this case the lamp may need to be replaced

I hope this has been useful

Plug the power cord it into the wall socket. Plug in the phone wire. There is an On/Off switch on the back. You will need some thermo-paper that comes in a roll, a roll like toilet paper, thinner than regular paper. The instruction of how to load it is on the top paper cover. Good luck

3M model 45CG Thermofax Machine how to change bulb?

On either side of the drive table are single wires that go to each end of the lamp. Remove one screw on each side of the snap-in levers. Turn red handle on left side of unit as you are looking at it. Lift up each lever (screws you just removed) carefully. You can slide the entire unit out from under the clear plastic, then you will be able to see the lamp. It is a long halogen lamp. Do not touch the lamp with your fingers!! The oil on your skin will cause that area to overheat, boil, and blow. Disconnect wires on each side. Loosen bracket screws (2 on each side). Lift lamp out of heatsink tray by porcelain ends and slide out. Replace in reverse order. REMEMBER: DON'T TOUCH LAMP WITH FINGERS. USE GLOVES OR HANDLE BY PORCELAIN ENDS. GOOD LUCK!!
