I bought a IBM T30 from e-bay which has no video on the LCD. I hooked a external monitor which works fine. I switched the LCD, Video cable, Inverter board from my other working T30 to make sure all these parts are good but still can not get video on the LCD. I have also changed narrow circuit board with the close lid switch and still no luck. what else can be wrong except to change the motherboard? any help, thanks. Albert
Hello Sellar, Am tony Auditch from uk i need your items for my Wife in west African so i want you to send me the total cost of the item+ the shipping cost. here is my Email email@example.com_auditch@live.co.uk tThinks
That has happened to each of my T30s, 3 times altogether. Drop or jolt damages the mobo. I've tried swapping parts (incl. LCD) between machines to no avail. The only fix was to replace the mobo, and that worked every time. BTW, shining a flashlight at the LCD, you can barely see an image, but it's there. But the problem is the mobo, not LCD, not inverter card, not LCD ribbon cable.

You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8
The bottom left key is labeled in blue, Fn. Hold down this key and press the F7 key at the same time. Repeating this will toggle between an external monitor and the LCD. If this does not work, try connecting an external monitor to the blue 15 pin VGA connector on the rear panel of your T30 and try this again. If you get external video you will know your video chip is working properly, but your LCD may not.
You didn't provide enough description of your problem to help you further.
Either you can hook up an external monitor or access BIOS setup (Basic Input/Output System) to replicate if the horizontal line appears. This step will check if the problem is with the video card or the LCD.
If you get the horizontal line on the BIOS or never get it on the external monitor, then surely the LCD screen is beginning to fail. You need to reinsert and/or replace the LCD inverter or LCD itself.
However, if you see the horizontal lines on the external monitor but not on the BIOS, try to update the video driver. If this will not resolve the issue, you need to replace the video card or the motherboard of your laptop.
Do you hear any startup sound when you turn it on? If there is, try hooking an external monitor. If it has good display, replace LCD, if not then it may be a videocard problem. possible motherboard replacement will resolve this issue.
Try to attach EXTERNAL MONITOR to check if you have display from External Display and to confirm that your Laptop System is still working. If you got display from external monitor, therefore you have a faulty LCD / Inverter (gives your LCD a back-light)
When you connect a data projector or a monitor to the video output connector on the laptop you can toggle the display in various configuration by press and hold the blue Fn key and then press the F7 key (once or a couple of times as required) this key has a blue symbol of a pair of monitors.
Press it once the LCD will switch off and the display will switch to the external video output.
Press it again and the display will be on both the LCD and the external video output.
Press it again and the display will be only on the LCD.
It means computer developed oxide on some contact, and this is causing a short that forces unit to shut down, laptop must be taken apart, dried properly, and eventually cleaned with circuit cleaning solution. If problem stops when you turn to external display, then probably it is water or oxide in LCD ribbon cable connectors.
Yes you can do that by trying to set the sesolution settting.

2.Under Display Properties window click the last tab name settings
3.Below you should be able to see Screen Resolution
4.Try to adjust the resolution here.
** Please try to reduce the resolution ...or sometime add more resolution
try hooking it to an external monitor and see if it works.If it does then you need to check which part is bad.Possible defective parts in order of the cheapest is :inverter card,then LCD Cable,then LCD Display,then system board.If it does not work with external monitor then try drivers or system board because the video is built into the board.If all else fails I will buy it from you if the price is right.
