Hello
Look for some external materials like hard flyes or such small and hard materials in between the leaf of the fan, which make noise. It is quite commot that flies are trapped inside it. If so, open your device and clean the fan leaf. Do it very carefully not to make it break. If there is no such materials, and still fan has sound, peel off the the label on the fan, and you can see a bush joint that comes from inside where the shaft of the fan is fitted. Put a drop of lubricatin oil and see whether it helps you. If note of this helps you, just repalce the fan with a similar one. OK.

The bulbs on projection tv's are typically designed to be replaced by the owner of the TV. They are a big pricey though. Do a good search online to try and get the best price. There will usually be instructions included with the replacement bulb. If not, visit RCS's website and download the manual. The unit that needs to be replace is typically located on the back of tv and secured with several screws. There will be a wiring harness to unplug and the unit will slide out. Just replace the bulb and reinstall the unit. Remember to NEVER touch the bulb itself with bare hands. Any oils from your skin can cause the bulb to prematurely burn up or even break immediatly when turned on.

The tv shuts down because the protection system of the power source detects an excessive current on one of its outputs and cuts it down.To find out the failing part that consumes extra current you will have to check the output voltages - start with the wheel motor and its power line.
And, as usual, don't forget to check all the capacitors .

Hello,

The problem with the tlevision is that either the lamp is faulty or the t-com board is bad.

First ensure that your television is not display is not turned off from the menu and there is not screen saver set up on it. if that has been confirmed, then the problem is from either of the afforementioned causes.

To check if it is the lamp, then you have to unscrew the television open then assess the lamp, if it looks burnt or broken, then you replace it with a new one, and if the lamp looks okay then it is the t-com board that needs to be replaced.

Take care and good luck
