Question about PC Laptops

1 Answer

Lamp When turned on, lamp comes on dim as usual. What is different now is that after about 30 seconds, the lamp indicator light flashes three times and the turns off and the power/standby light goes to red. At the same time the lamp shuts down without ever going to full power. Can,t seem to get an image to my TLP-MT4. What do I need to do?

I'm still not sure about your question. Let me quess that by saying power/standy light goes to red...that mean your computer
is going into standby mode.!!!! So do it this way..on the left or right top corner of your notebook not the monitor, you should be having a small pin pointing up..I think that pin is use when you close the lid of your Laptop and it make your laptop goes into standby mode.When I mean goes into standby(sleep mode) the first think you can notice that your monitor light will be off and you can still see a very light image.So maybe this pin is stuck try to push it down for several times..
best of luck, takecare

    Ok I got your point.I check manual of Toshiba it seem that the problem is from the Lamp cover is not properly closed.So what you do is open the outer lamp cover and you should also see the inner lamp cover.Take the lamp off and reseat it back.Put the inner lamp cover make sure you screw it tightly and also the same for the outer cover.

    ** Please becareful make sure the you do it after you turn off the projector for atleast 10-20 minutes..cos the lamp is very hot!!!!

    best of luck again...takecare

My compuetr screen does light up when power is connected it dark


You may have a faulty inverter or defective CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight or a faulty inverter that supplies high voltage to the CCFL lamp. Usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
