Whenyou connect the power adapter into the laptop, does the power LED light up? Ifnot then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

If you have tested your power supply cord with say a voltage meter, and it is working, then the problem lies with your motherboard. Do you have a charged laptop battery? If it powers on with the battery, then the problem is isolated to the power plug port on the motherboard.

Infocus IN34 all indicator lights on


Power Supply problem. Check for "Bulged" capacitors in the output circuit ( 5 parts 470uf @ 16VDC). Also an indication of this problem is to remove the lamp cover and plug in the AC power cord. If the fans run slow....this is the problem.

First check your bulb properly matched with your projector. After changing the lamp reset the lamp hour (counting from 0hrs). Adjust the osd transparency.

If u set the lamp properly then It may cause the lamp circuit need repair.

Have you got yellow lamp indication before change the lamp? If occur then you have been late to change it. If you used it up to 2500hrs. then this problem may arise. Check those first if everything ok then may be the circuit have some problem, go to the nearest sharp authorize service center or visit website.

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

The lamp indicator turns on


The clicking noise is the protection switch that keep shutting down the unit. This happens when an internal fault had been detected.

Do the following:

Unplug the unit from power for some time.
Remove the bulp and refit it in place.
Restart the unit.

If still in protect mode (clicking , lamp light and no start), then there is a fault.
When the problem is the lamp, the lamp light will come on, but usually protection does not click.
Before buying a new lamp that is expensive, have the projector checked, testing with particular attention the high voltage board that will supply power to the lamp. That may be the fault.
If you have a replacement lamp in storage replace the lamp first.

LP 240 stopped working. No lights, no fans, nothing.


Please describe the status of the LED indicator. No LED would indicate a failure of the power supply. I can help you with that.
Flashing red would indicate a fan/lamp problem. Some lamps fail prematurely before the lamp hours are up.
If it is the power supply, no lights at all, I can get you running again. These units have fragile power supplies that can burn out with the slightest power surge. A UPS goes a long way to save future headaches.

Hi there

Replacing the lamp won't make any difference at all.

If you have checked the fuse on the Powersupply Board and it tested ok , then the whole Board will need replacement.
