Hi Bedlam

This could have been a faulty lamp , or if it wasn't a original - in other words a Utopia lamp - that the wattage wasn't right.

Contact the supplier and tell them that the lamp blew as soon as you replaced it. The lamp should have a 30 day warranty on it.

As for the Projector , in such cases it is normally only the fuse on the Powersupply that has blown. Replace the fuse and see what happens.

If you still struggle , drop me a posting and I'll get back to you ASAP.

Good luck and thanks for using Fixya !

Loud bang from system.Unit starts immediately power is supplied.Power switch does nothing.H/Drive and players run.No video ( card OK ) checked with another card. Can the problem be motherboard?


The load bang is most like an exploding capacitor in the switch mode power supply, especially if there is a burnt electrical smell from the power supply.
I suggest you borrow a switch mode power supply, remove the old power supply and install the replacement power supply. make sure it has the same or larger wattage unit.
If the computer still does not boot up then the exploding power supply has damaged the motherboard, and you need to replace then motherboard too. This may not be a cost effective solution.
This is an opportunity to get a new and better computer.

Panasonic PT-60LCX64. What would happen if you


you won't get another warning for 2000 more hours on a lamp that is good for only 2000 hours (give or take). so, if you don't replace it, you run the risk of the lamp exploding at the end of it's life, sending shards of glass and mercury dust throughout the projector.

TURN PROJECTOR ON. FAN TURNS ON NO LAMP, RED SATUS LIGHT COMES ON


Bulb timer has expired. Press the left arrow, right arrow and power switch simultaneously for a few seconds. The projector should power up, but this indicates that a new bulb is required and should be fitted as soon as possible, as there is a risk of the old bulb exploding.

My Sharp XR-40X DLP Projector bulb will not start. The bulb is not near the end of it's projected life nor did I get the "Replace Bulb" warning indicator. It has power and the fan comes on.


Hi Just be aware that the stated lamp projector specs "2000 hour lamp" does not mean you will get 2000 hours. What it means is that the lamp is rated to deliver up to 2000 hours. So some might get 1000 hrs, others 1593 hours etc.
The lamp may have died of its own accord prematurely and obviously unexpected.
With the power and fan coming on my first throughts are either the lamp or the lamp ballast (powers the lamp).

Exploding Bulb


remove the top of the projector (remove the 6 screws on the bottom and the top 2 screws on the back), use canned air, and blow every piece of dust out of every nook and cranny. also, don't get cheap lamps from "bob's house o' lamps". get the AN-XR10XLP/1 from a sharp dealer to get the full life out of a lamp. also, make sure the vents on the projector are not blocked when you use it.

The lamp exlpoded


I assume you have fitted a new projector lamp. If you have then I think the problem will be in the power supply, transformer. In part one clue might be the age of the lamp in terms of identifying the reason of the lamp exploding. Regards Kevin Andreassend ICE AV Technology Ltd http://www.iceav.co.nz. iceavtech@gmail.com

check to make sure your lamp is completely in and connected properly, and the lamp door is closed completely, if still no light, pull the lamp out and make sure it is not broken from transporting it or handeling it.

Making sure you do not touch and glass portion of the lamp or surroundings. only touch plastic or "metal using clean dry paper towel for metal contact" as skin oil can destroy a lamp.
