Infocus x2 burned out new bulb in one weeks

Hello :

Here I'll tell you how to replace it :

1. Make sure that your power switch is off and that the power cord is unplugged from the electrical socket.
   It is also wise to unplug any other cables and label them in order to restore them in the right way once the lamp is replaced.
   
2. In order to see the lamp, remove the access handle on the outside cover. You may need to use a screwdriver.
   
3. Pull out the used lamp and clean the relevant parts using micro fiber products and not paper.
   Please note that in some projectors a small inside filter should also be replaced.
   
4. Insert the new lamp into the projector carefully avoiding touching the glass of the lamp itself.
   Touching the lamp will deposit skin oil that will likely damage any new lamp during use.
   
5. Reassemble the access panel, repluge the cables and power up the projector.
   

• new projector lamp
• screwdriver
• micro fiber duster

• avoid touching the bare projector lamp

The only part that usually will cause premature failure of the lamp would be the ballast itself. The ballast is what powers up the lamp. It can not be checked except visually for blistered capacitors otherwise its a replace item only. If your projector has air filters make sure that they are clean as well make sure any fans used for cooling are rotating.

If this was a new bulb and burnt out for seeming no reason the most common thing will be that you touched the bulb. The oils on your skin will adhear to the glass and the bulb is hot enough to cause the glass to fail at the spot where it was touched. Be sure not to touch bulb and if you do clean with a soft cloth and rubbing alcohol. Always use tissue or soft CLEAN cloth to handle. Hope this helps. Good luck.

The fan is to cool the internal part of the projectors.but in your case the fans are not able to cool the internal parts so you need to keep the fan more five minutes to cool the internal parts. most probably the problem is the fan speed its not spinning that fast so its taking some more time to cool the bulb as well as other heated parts. so also replacing the fan will help.but in some rare case the wires which you replaced for power supply to fan.that wires are bit thick from original or bit thin from original.the gauge of the wire is not same.in this case the wires needs replacement other wise its the fan speed problem. This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

The most common cause for burning the bulb is overheating. To get the best life and brightness you must ensure that all filters and airflow ducts in the projector are absolutely free of dust.

also, make sure the proper tools are used while changing the Lamp/ Bulb.

See the guideline from below website.

Have a great day.
Rate please if it helps.

The output transformer for the bulb is at fault producing to much power burning the bulb out quickly

Hi

Thank you for your query

This is a common problem amongst projectors, however my only key advice is that the lamp/bulb you purchase is off a high quality one, there are alot of bulbs out there which are cheap but which burn out quickly

In response to your question unfortunatley short of taking the projector apart to see if there is a power surge somewhere causing the bulb to short, there are no tests as such.

I hope this has been useful

Yes you can check out the Power supply to the lamp, this is most likely high and it shouldn't be. You will simply have to check to see if the voltages are correct at this unit's circuit board. but before doing this you simply MUST get a service manual for your set. In there you will find troubleshooting guides, and what the Voltage levels are for all sections of the set. unfortunately there can be many number of reasons that this is happening. There is never a this-is-it, this-is-what-to-do, as there are so many interconnected "Rails" and connections and it can be dow any one of the number of branches that join in and supply it. You need to check for AC "Ripple" on said rail. look for faulty Electrolytic Capacitors, (These are a prime culprit) and or failed Voltage Regulators, and or Zener/Signal Diodes. Overheated components often cause this too. Check the components on the Power board for signs of heat damage etc. I have been doing this now for over 25 years and never the two the same, oh sure some faults have a common cause but theses are all well known about and have "Other" symptoms as well that give it away. You see the "Lamp" is ONLY A SYMPTOM, of the actual problem. and NOT the "Cause". This is where us Engineers earn our "Salt" as this is where it takes the experience and instrumentation, usually an Oscilloscope, to locate and fix the unit. Now, If you find that the job is too complicated . please get a firm "Quote" for a fix before proceeding with any repair.

If there is any oil on the surface of the bulb,this will happen,When replacing the bulb,do not touch the bulb itself with your fingers,if you do,and it is good to do this anyhow,clean the bulb with alcohol,because you do not know who all might have handled the bulb during packaging,or just took it out of packaging,and handled it,

Hello. Generally the problem is a poor bulb, not a faulty projector socket. If you have a volt meter you can check the voltage in the socket but i seriously doubt that the problem is with the projector.

Be careful not to move the projector when the bulb is hot. When you turn it off, leave it sit for at least 30 minutes to cool as a hot bulb is a delicate bulb. Joe
