Re: Monitor went black completely dead
A simple way to check your AC Adapter, plugged into a socket and see if it lite green... If you don't see a green light lite on the AC Adapter, then it's DEAD... You can order the AC Adapter @ www.3rd-rocks.com but sometime you need to replaced both. Have a nice day!
A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones). click here to download the app (for users in the US for now) and get all the help you need. Good luck!

Hi there... First check your AC Adapter, see if it still lite green. If it not then you need a new AC Adapter. If AC Adapter still lite green, then your back light inverter are busted. It's more likely your inverter are busted... I can repaired for you... for more information @ www.3rd-Rocks.com Thanks, have a nice day!
Have you connected to an external monitor, just for fun? Try that, don't run off the battery, in fact, take the battery out. Use only the ac adapter for power. Now boot pressing f1 repeatedly until you get into bios. Just let it remain in the bios screen for a few minutes, long enough to prove you don't have a hardware problem such a s the inverter going out, etc.
Then allow it to continue to boot to windows. If it appears on the external monitor (may need to hit Fn+F5 or F&, to utilize both monitors), but not the system monitor, it's possible you've got a bad piece of hardware such as an inverter going out, or even the backlight failing.
If there's no image on either monitors, but you hear the usual sounds of windows booting up completely, it gets tricky.
First think is to update to most recent bios.
Floow the directions from the Lenovo site for the T20. Use the floppy image; it's just easier.
Let us know how it's going.
The board with 200-100-SH700 on it may be the problem. I came up empty trying to find anything with that number, there should be some other number either ink-stamped on the board or on a paper sticker. Google can be your friend if you find the right number. Somewhere there may be someone with one of the same with a broken screen. Ebay?
The specs for this monitor is a 60 Watt, 12 Volt, 5 Amp power adapter. The voltage must be the same. You can always get an adapter with a higher Amperage rating, but never get one with less, as this can overheat the adapter and damage it. I was not able to locate specs on whether the voltage to the monitor is DC or AC... most are DC. If this is the case, the observe the polarity at the monitor. Power adapters have a positive and a negative... center and outer contact, Make sure that the power adapter matches that of the monitor, else it will not work.
It's your backlight adapter. You will have to open up the monitor to get to the backlight board and redo some soldering and maybe replace the four transistors. I just did a google search for the name of the monitor and there are plenty of posts out there to help. I had the same issue with my monitor. I redid about 15 or 20 solder joints and that fixed it. There transisters cost about $5 on ebay if the resoldering doesn't work. The problem is what is called cold solder joints. These are used in mass production circuitry, which is why so many electronics go out. These joints are a dull gray and hot solder joints are a shiny silver, these should be replaced, but just google the name of the monitor name and you should see plenty of others that had the same issues years ago.
LCD monitors use CFL lighting behind the liquid crystal display. There is an inverter circuit just for the CFL lights which requires some of the DC current from your adapter to be converted back to AC. most likely your inverter was blown.
Your only solution, in that case, is to take it to a repair shop to have any blown electronics replaced... or just get a new monitor (which might be about the same price as a repair).
It's seems your Inverter or AC Adapter is burnt out. Check if your AC Adapter is still on green light. If no green light, then you'll need replace a new one. If AC Adapter it OK, then you'll need a new Inverter. Drop me a note, I'll give you a good price. Thanks email@example.com
You can get an adapter for a similar model here: http://www.partstore.com/ModelNumberSearchTween.aspx?MfgID=1747
You'll have to contact them and ask if they ship to Australia though, if they don't, hard to say who will.
I would contact Benq(you have their email support here on the product page) and ask them If you could- a. use an adapter to a similar model. b. use a generic adapter with the same electricity specs, and then consult a local electronics lab.
