I have a mt3703 laptop and the screen just goes black after a few minutes after I turn on the laptop. Is it the inverter or the backlight that needs to be replaced? I used a monitor to make sure I still have video and it works, and once in awhile the laptop screen will flicker on and I can see the screen for a few seconds or so. if this helps to tell me weather it’s the inverter or the backlight? The image on the screen isn’t visible at all when it goes out
.Thanks for any help

Please can you tellme where to buy it, or the number of the cable, because my problem its the English I cant explain how to say the correct cable to buy itâ€¦?

I don't know the part number. Take a look at the cable installed in your laptop. Does it have a sticker on the cable? The part number could be printed on that sticker. Find the sticker and google all numbers you can find on it. You should be able to fine a new cable this way.

Not, its not the inverter, I put the new one, and the screen its black, some times I can see the desktop but darker... well I need to do 2 things... 1.- buy the whole lcd screen, and second, I need a new cable ( the left what as atached to to inverter ) because when I try to disconect again the new inverter to see the exact number of my lcd screen, well I put excese force and I disconect two black wires from the "White head cable" and I dont know were to put inside again back... Mr IML Tech, in the step 4 you say "Carefully disconnect the screen backlight cable from the right side of the inverter board" that cable its ok, but if you see in the same steep , you say "If you are replacing the inverter board, youâ€ll have to disconnect one more cable from the other side of the inverter" that cable I broken, because some wires its out from the end of the cable, thats its the broken cable.. Please can you tellme where to buy it, or the number of the cable, because my problem its the English I cant explain how to say the correct cable to buy it...??? thanks for your reply

Mr IML Tech say: 2. The laptop doesnâ€t react at all. No LED light, no other activity. The laptop appears to be dead. I need push the on button several times, until the computers starts on... because when I push the button the laptop its on number 2... I see this, (maybe .. I dont know certain of this ) but if I push the on button to start the laptop on, I push the button on one of piece of the button on the left around ( not on the center ) and stay pushed the computer its on... but not on all times... today the laptop continues turn on ( pushing several times the buton ) but what I say, Iam afraid one day the laptop never start on...... thanks and regards .

the â€œonâ€ button its hard to respond ( I push several times and spend several times ) until the laptop its start onâ€¦ Im afraid next time dont turn on the laptopâ€¦

What happens when you push on the power button? 1. The power LED turns on but nothing appears on the screen or 2. The laptop doesn't react at all. No LED light, no other activity. The laptop appears to be dead.

Thanks Mr IML Tech.. many thanks for your explanation, right now I buy on ebay an inverter, to test first ( hope this can fix the problem ) and if its not, well I need to replace all the lcd screen, becasue what you say its difficult to change only the backlight.
but Iam happy with your repply, first for your time to respond, second for your website with images explain to change the bad parts, because its good to me, and have the courage to make my own job in my laptop… ( some people do the job but its givme an expensive amount, thats scare to me…. 190.00 dlls … and I think, my computer its old , so its better if not repair and buy a lcd screen separatly to buy in walmart for 100.00dlls and thats its less than sent to repair ).
again thanks for all, and only wait for the part to do the job..
regards
Homer

In reply to Homero Iracheta. Homero Iracheta, Most likely it's either bad inverter board or failing backlight lamp inside the LCD screen.' Which one is bad? I cannot tell without testing the laptop. Both have very similar failure symptom - no backlight on the screen or it's flickering. In order to figure out which part to buy, it's necessary to test the laptop with another inverter or backlight. If you have no spare parts, you'll have to guess. I would suggest try replacing the inverter board first, it shouldn't be very expensive. If it doesn't help, replace the LCD screen (the backlight lamp mounted inside the screen). It's possible to replace just the backlight lamp without replacing the whole screen, but it's very difficult.
