Black dimmed screen continued. *help*

So I have replaced the Invert board that didn't fix it. So I figured it was the Backlight so i bought a new backlight and sent it in to a repair shop to replace it.

Now the repair tech calls me and says, it gonna take him some time to figure out how to replace it and that it would cost me more then buying a new LCD screen. . .

So I then bought a new LCD screen replaced it myself and it booted up and the screen was working fine, until i ran a stability test, black dimmed screen again..

Yesterday I sent in the laptop again to the repair shop to find out what is wrong. And he says its the Invert board that I have already replaced. I'm not sure if it is that since its totally new. So I asked him if there is away for him to check it. And he has checked it by connecting another LCD display to it and it had the same Black dimmed screen.

Is it the inverter board or could it be something els? I'm tired of wasting money now. And i'm starting to have my reservation against the IT tech. Is it that hard to troubleshot this?

 

In your other thread, an NBR member offered to fix it for the cost of shipping. Maybe it's time to take him up on the offer.

 

Well then its trust involved. I don't know the dude and I live in Norway, so it would be a long way to track him down. If he stole it or anything should go wrong then I have no guaranty.

 

From my limited knowledge of reading on these forums, the inverter boards can vary from model to model of laptop, and can vary between screens that are installed throughout the production cycle of a model. I believe they have serial #'s that have to match up for them to work as intended. Either way, they are really cheap and plentiful on ebay, especially for laptop models that are very common. You should post more specific information about the model numbers of your laptop and the lcd, and maybe someone can tell you exactly what you should look for. My best guess is that the inverter board is either wrong for your laptop, or when you used the good inverter with a bad screen something got messed up with the new inverter.

There could be a component before the inverter that is causing all of your trouble as well.

 

My Model is a Clevo M570TU. The Inverter i bought was this one PWB-IV13122T/A1-E-LF parts (whiteout power LED light). And the display is this one PROSTAR M570TU LAPTOP LCD SCREEN 17" WSXGA+ MATTE CCFL $178.99, The Inverter Board is the exact part nr as the old Inverter Board.

 

This is SOLVED! It may be miss leading with the symptoms I had because the black dimmed light problem most of the time is fixed by changing display, backlight or the inverter. But my card suddenly didn't work on my external screen anymore so I didn't care since it was broke. I tryd the baking method oven at 200c and placed the card on 4 aluminium balls and had it in there 10min and guess what it WORKs now! This is for a GTX 8800M.
