    Hello. The lamp is OK because it is used just below 100 hours(I think 20~30hours). As I said,
    "Just white light is projected." It seems to me that initial boot sequence of LP350 to display the welcome view(top view) is incomplete.

  • ymats0703 May 22, 2011

    Please give me some hints for my trouble!

  • ymats0703 May 22, 2011

    LED seems to be OK. The LED is green and the fan is working. The lamp is ON. The remote controller is working. The menu lamp is working when I push the menu button. But the boot sequence seems to be not working. Although it is my understanding that an initial booting program is to run, am I correct?

  • ymats0703 May 22, 2011

    Thank you for your advice. It is now difficult for me to upgrade firmware because I don't have device to connect a PC and LP350 through RS232. So I would like to try reset Lamp Timer. I have tried "Check Lamp Hours". -- what is "status"? Is it a button? Nothing changed. "Reset the Lamp Timer" You said, Volume - : on my computer display, I can see like Volume question mark. Is it Volume minus? I assume Volume minus. And the result is nothing change. If this action works OK, what happens?

  • ymats0703 May 22, 2011

    What is kuatiri? And I can not understand why a spare lamp is required. As I said I have not used it for a long time, only 20~30hours. Even so do I need to prepare a spare?

  • ymats0703 May 22, 2011

    I bought it several years ago. No warranty is available. As you said, I should assume two kinds of possibilities. Firmware and light. I don't want waste my money. Again, why a spare light is required? I will do firmware upgrade.

Check or swap out your cables. If using a usb cable to connect make sure you connect it to a port directly on your computer and not thru a usb hub. I have attached a link to the pdf manual click download if you don't have one.
See the trouble shooting guide starting on pages 36-40.
Many laptop computers do not automatically turn on their external
video port when a projector is connected. Go to page 44 to see if your computer is listed.
This should answer all your questions and if still not working there are contact numbers if the unit needs to be professionally serviced.
Thanks for using FixYa.

Hi..
view of your statement, I believe your problem is the projector lamp. to make sure they try to do troubleshooting on your projector.

1•Make sure the lamp has not been in use for over 2,050 hours.
The lamp automatically shuts off at 2,050 hours and the LED
blinks orange.

2•Check the projector's lamp to ensure that it is securely connected
in the lamp module. Make sure the lamp door is
installed.

Replacing the Projection Lamp

WARNING: To avoid burns,
allow the projector to cool for at
least 30 minutes before you open
the lamp module door. Never
extract the lamp module while the
projector is operating.


The lamp hour counter in the Status menu counts the number of
hours the lamp has been in use. After 2,000 hours of use, the message
"Change Lamp" temporarily appears on the screen when
the projector is turned on. Change the lamp within the next 50
hours. After 2,050 hours, the LED flashes orange and the lamp
will not light. You can order new lamp modules from your InFocus
dealer. See "Accessories" on page 42 for information.

Follow these steps to replace the projection lamp:
1 >Turn off the projector and unplug the power cord.
2 >Wait 30 minutes to allow the projector to cool thoroughly.
3 I>nvert the projector on a soft flat surface, then insert a small
screwdriver or other flat object into the tabs on the lamp module
door and gently pry the door up.

After powering on my LP350, - multilinkent_10.jpg 4 >Pull the lamp door up and remove it.
5 >Loosen the two non-removable screws on the outside of the
module
WARNING: Be extremely careful
when removing the lamp module.
In the unlikely event that the bulb
ruptures, small glass fragments
may be generated. The lamp
module is designed to contain
these fragments, but use caution
when removing the lamp module.


multilinkent_11.jpg CAUTION: Never operate the
projector with the lamp door open
or removed. This disrupts the air
flow and causes the projector to
overheat


6 >Lift and grasp the pull tab and lift the module out (Figure 22).
Dispose of the lamp module in an environmentally proper
manner.

multilinkent_12.jpg WARNING: Do not drop the
lamp module or touch the glass
bulb! The glass may shatter and
cause injury.


7 >Install the new lamp module, being sure to align the connectors
properly.
8 >Push the module in until it is flush with the bottom case of the
projector.
9 >Tighten the screws on the outside of the module.
10 >Replace the lamp door by inserting the hooks on the lamp
door into the slots on the projector and pressing the lamp door
into place. If the lamp door does not fit properly or bulges out,
remove the door and re-seat the lamp module.
11 >Plug in the power cord and press the Power button to turn the
projector back on.
12 >To reset the lamp hour counter in the Status window, press
and hold the volume - button, then press the menu button
(while still holding down the volume - button) for 5 seconds.
Verify that the counter was reset by pressing the menu button
and viewing the counter in the Status window

    Can you hear the fans or see any LEDs on the top of the projector?

  • HTS Sri Aman
    HTS Sri Aman May 22, 2011

    If you see the LED blinks or does not see any flashing LED. try to reset the Lamp Timer or update your firmware ( CLICK HERE TO DOWNLOAD FIRMWARE )will most likely solve your problem with the lowest cost. If after a few things but still failed to function this means that it has internal problems that normally would be done if you do the maintenance that is usually resolved by an expert in offline or service center that provides such services.

    Tips

    Check Lamp Hours
    > Press the Menu button, then select Status. After 2050 hours the LED flashes orange and the lamp will not light until the lamp is replaced and the timer reset.

    Reset the Lamp Timer
    > Press and hold the Volume –, then press the Menu button. Hold both buttons down for 10 seconds

    I suggest you do the first firmware update for the kuatiri it is only software problem and the problem you are close to these two problems
    (firmware problem and the problem of lamp)

    but when you have finished doing some things and it was still the same problem. I suggest you get a spare lamp for the final tests, and there are beautiful you did a test on the side of providing repair service near you for the final if you need it.

  • HTS Sri Aman
    HTS Sri Aman May 22, 2011

    fear is only a matter of software
    yes you need to get spare parts if a problem in the light.
    But, if still under warranty , you better do warranty claims.

My desktop suddenly suspended, switched it off by pressing the power button. Now it does not boot, the screen stays dark, though power lights on the PC and keyboard are on. What should I do?


You are the owner of a desktop PC that has developed a sudden and catastrophic hardware
fault - probably on the motherboard (since even the ROM BIOS doesn't give evidence of its
existence), but possibly in the power supply.

Desktop PC power supplies are (relatively) easily replaceable, so if you have as many spare
power supplies lying around as I do, try replacing that first - if that doesn't fix the system, then
the problem is on the motherboard.

Since your power supply is alive enough to light the power LEDs on the system unit tower and
also the keyboard, the problem is probably on the motherboard - look at it - there may be an obviously burned visible component - but there usually is no visible sign of the fatal failure.

The reason I do not suspect your HDD (hard disk drive) has crashed is that ROM BIOS
executes at (power start) boot time right out of motherboard-mounted ROM, independent of
whether or not the HDD is functional - and since not even the BIOS message appears on your monitor, I therefore know that the boot sequence has been interrupted long before the computer becomes intelligent enough to find and access a disk drive, and then command it to try to find a
boot sector.

How to fix the computer: isolate the boot problem to the motherboard. Replace motherboard.

Tell me aboout boot sequence in bios setup


The system BIOS is what starts the computer running when you turn it on. The following are the steps that a typical boot sequence involves. Of course this will vary by the manufacturer of your hardware, BIOS, etc., and especially by what peripherals you have in the PC. Here is what generally happens when you turn on your system power:
The internal power supply turns on and initializes. The power supply takes some time until it can generate reliable power for the rest of the computer, and having it turn on prematurely could potentially lead to damage. Therefore, the chipset will generate a reset signal to the processor (the same as if you held the reset button down for a while on your case) until it receives the Power Good signal from the power supply.

When the reset button is released, the processor will be ready to start executing. When the processor first starts up, it is suffering from amnesia; there is nothing at all in the memory to execute. Of course processor makers know this will happen, so they pre-program the processor to always look at the same place in the system BIOS ROM for the start of the BIOS boot program. This is normally location FFFF0h, right at the end of the system memory. They put it there so that the size of the ROM can be changed without creating compatibility problems. Since there are only 16 bytes left from there to the end of conventional memory, this location just contains a "jump" instruction telling the processor where to go to find the real BIOS startup program.
The BIOS performs the power-on self test (POST). If there are any fatal errors, the boot process stops. POST beep codes can be found in this area of the Troubleshooting Expert.
The BIOS looks for the video card. In particular, it looks for the video card's built in BIOS program and runs it. This BIOS is normally found at location C000h in memory. The system BIOS executes the video card BIOS, which initializes the video card. Most modern cards will display information on the screen about the video card. (This is why on a modern PC you usually see something on the screen about the video card before you see the messages from the system BIOS itself).
The BIOS then looks for other devices' ROMs to see if any of them have BIOSes. Normally, the IDE/ATA hard disk BIOS will be found at C8000h and executed. If any other device BIOSes are found, they are executed as well.
The BIOS displays its startup screen.
The BIOS does more tests on the system, including the memory count-up test which you see on the screen. The BIOS will generally display a text error message on the screen if it encounters an error at this point; these error messages and their explanations can be found in this part of the Troubleshooting Expert.
The BIOS performs a "system inventory" of sorts, doing more tests to determine what sort of hardware is in the system. Modern BIOSes have many automatic settings and will determine memory timing (for example) based on what kind of memory it finds. Many BIOSes can also dynamically set hard drive parameters and access modes, and will determine these at roughly this time. Some will display a message on the screen for each drive they detect and configure this way. The BIOS will also now search for and label logical devices (COM and LPT ports).
If the BIOS supports the Plug and Play standard, it will detect and configure Plug and Play devices at this time and display a message on the screen for each one it finds. See here for more details on how PnP detects devices and assigns resources.
The BIOS will display a summary screen about your system's configuration. Checking this page of data can be helpful in diagnosing setup problems, although it can be hard to see because sometimes it flashes on the screen very quickly before scrolling off the top.
The BIOS begins the search for a drive to boot from. Most modern BIOSes contain a setting that controls if the system should first try to boot from the floppy disk (A:) or first try the hard disk (C:). Some BIOSes will even let you boot from your CD-ROM drive or other devices, depending on the boot sequence BIOS setting.
Having identified its target boot drive, the BIOS looks for boot information to start the operating system boot process. If it is searching a hard disk, it looks for a master boot record at cylinder 0, head 0, sector 1 (the first sector on the disk); if it is searching a floppy disk, it looks at the same address on the floppy disk for a volume boot sector.
If it finds what it is looking for, the BIOS starts the process of booting the operating system, using the information in the boot sector. At this point, the code in the boot sector takes over from the BIOS. The DOS boot process is described in detail here. If the first device that the system tries (floppy, hard disk, etc.) is not found, the BIOS will then try the next device in the boot sequence, and continue until it finds a bootable device.
If no boot device at all can be found, the system will normally display an error message and then freeze up the system. What the error message is depends entirely on the BIOS, and can be anything from the rather clear "No boot device available" to the very cryptic "NO ROM BASIC - SYSTEM HALTED". This will also happen if you have a bootable hard disk partition but forget to set it active.

I am doing a clean install of windows 7 on my Acer T180 and I need to set the boot sequence to cd-rom first. How do I view the present boot sequence and how do I change it to cd-rom first if necessary?


As soon as you power on your laptop, you want to start pressing F2, it depends on who made the motherboard if it is not F2 then the key to access your "system setup" will usually be displayed in one of the corners during POST This is the initial startup routine of any pc this is the screen you will see the ACER logo appear.
Once you are in there you will want to be careful of any changes you make, the command you are looking for is the (boot sequence) on most PC's the (+) (-) symbol is the way to toggle your choices after you have placed the cdrom first in the sequence then save and exit and on the next startup the pc should know to look to the cdrom to load the install disc. Let me know if you need more help

Fujitsu-Siemens P15 TFT power/picture problem. it take time to turn on.


It does indeed sounds like the capacitors, I had this problem last year with a Medion monitor where it would turn on and off, when I spoke to Medion they did say that it would need a repair but at the time I wasn't enclined to pay the repair fees for something that may happen again!

Personally I would stick with your plan of getting a new monitor because my view on monitor hardware issues is that if it's happened once it will happen again even if you do repair it resulting in a lot of hassle!

Infocus LP350 won't show signal, also panel buttons don't light up


Hi LuckyLindy

Next time this happens , just take out the main connection to the Mainboard and plug it back in.

Also remember to reset your lamp timer now that you have replaced the lamp !
