Question about IBM ThinkPad T40 2373 Notebook

1 Answer

Display cuts off. Shutdown computer and it comes back.

My display will go dark. I can turn it off for a few minutes and it comes back. I have connected it to an external monitor and it works fine so the video card is probably OK. Can anyone help me?

    hvpatel had exactly the answer. I disassembled the display (my first time) got the part number, bought one on ebay for $12.29 including shipping, have just put it in and reassembled the display and it works like new. Many thanks.

    My IBM T40 2373 has developed two issues. If I have the unit in my lap and the laptop flexes at all, the LCD screen will go on and off as I apply pressure to the body of the laptop. The second problem which just developed is the laptop works just fine until I move it and as soon as I move it at all, the unit freezes and must be rebooted to get it working again. It is suddenly exceptionally sensitive to movment.

jackperson, Might be internal problem with the units power supply (ac line in to DC conversion) having shutdown issues. You will need to do some reading in my fixya profile for a while and then you will know what to look for inside unit. If not into electronic repair stuff, skip the reading and trade-in unit for new, if current unit is 4, 5, 6 years old. 12fixlouie

IBM T40 2373 display cuts off.


When it cuts out can you still see the display very faintly or does it just go completely black?

Fuzzy, unstable display


This sounds like a high-voltage power supply problem, which would need to be diagnosed by an experienced computer or electronics technician.

Check to see if there is a small focus knob on the back. If so try turning it back and forth three or four times to "clean" it....then adjust for correct focus.

Symptoms like this can also be caused by accumulated dust inside the monitor.

Display goes black after 5 minutes


Repairing the DELL E171Fpc LCD Monitor with the complaint of display shutdown after few seconds (power LED still on) was not difficult. Normally when this type of problem happens, we would first suspect the inverter board, then the filter capacitors and lastly the main board. A defective in one of the lamps and a faulty TL1451AC PWM IC or inverter ic may caused the display to shutdown as well. If the lamp is defective, it will send a feedback to pin 3 or 14 of TL1451AC IC and caused it to stop producing output signal thus the display just shut off once you switch it on.
