Toshiba Satellite L305D-S5900 LCD screen is completely blank & quit wo

Hello! I am trying to repair an issue on a Toshiba Satellite L305D-S5900 Laptop.
A couple of weeks ago, I installed a new hard drive, and installed Windows Vista on my cousin’s laptop listed above. He said it was running perfectly fine until 3 days ago, when he turned this computer on. It wouldn't show anything on the LCD screen at all. You can hear the fan going, but you can see nothing on the screen. I tried to pull this laptop up on an external screen, and still no screen at all. I can hear the fan, and that's it. I'm not even sure if the hard drive is even booting up. I also have checked the video cable to make sure it was plugged in correctly, and it was. I have removed the battery to see if that was the problem, and it wasn't. I also took out the hard drive to see if it was the problem and it wasn't...and took out the memory...nothing...i did all the testing and removing of all parts one by one, but still I can't figure this one out!!
Can anyone point me in some direction as to what the problem might be?
Thanks in advance to anyone who can guide me in the right direction....

I have also tried everything possible that i can think of and have been suggested to try....nothing seems to work. the mobo turns on, but it won't allow anything to work except for the fan....i get no screen, no hdd, no cd, nada! i haven't had any luck at all! what all have u tried doing? i have it down to the bare bones, and still can't troubleshoot what is wrong. i thought about trying a new motherboard, but they are expensive, even on ebay. and i'm not even sure if that is the problem, and would hate to be out the money if it isn't the problem. have any suggestions? have u called toshiba at all? thanks for responding....maybe between the two of us, we can figure it out...and possibly find a way to make toshiba give us new ones, like a silent recall...idk worth a try!

I don't even get that far. it won't boot at all! I can hear the fans, but that is all. i tried using an external monitor with this laptop, and nothing will boot. i have pulled everything out of this laptop, clear to the bare bones....and built it back again with testing all devices along the way....still nothing...my guess is its a bad mobo.

I still haven't found a fix yet, but will be ordering a mobo for it, because I'm almost positive that is the problem. the mobo is over $200, but it's worth a try. I already replaced the hard drive, the memory, and the power adapter in the last 6 months. If i were u i wouldn't buy anything for it, i would def by a diff PC and diff brand. I will NEVER own one of these! Unfortunately i have to fix it for my customer tho.

Any Progress on this ?
did the motherboard replacement work?

i currently have the same issue.
other problems i experienced during the same day (before the black screen).
-internet adapters stopped working
-restarted, internet works, but desktop icons have no images.
-shut down, turned on in 4 hours, Fans working + Black screen, no start up.

I have the same problem but my bios comes up,ctrl,alt delete restarts the laptop but nothing passed that comes up other than a 99%white screen,i have tried pressing F8 and '0' when booting but nothing happens not even a bootable cd...

chamaklio....i have the exact same problem, and don't have a fix except i'm almost positive its the motherboard, but are afraid to buy one in case it isn't what's wrong. The cost for another motherboard, and they are hard to find, is $250 and up to $350 have you had any luck with your yet? in the past six months i have replaced the hard drive, memory, and power adapter. I'm not sure if i want to waste anymore money. it's actually one of my friends/customers laptop, but he was willing to wait on fixing it, till i figured out which was the best thing to do, and i'm seeing that buying another one might be the best bet!

Hello all,

I am experiencing the same issue as previously identified. I turn on the computer, and I can hear the fan, but no screen / boot sequencing activity occurring. I wasn't sure if any additional ideas / fixes have been discovered in the meantime. During my searches for a potential fix, I discovered a similar thread with a "potential" fix. Seems this particular thread has some moderate success in fixing their issues. I have not been home to try this myself yet, but wanted to post it for other parties to try.

Can try a power drain !!

take the battery out n disconnect from the external power .

Hold on to the power button for 30 sec .

Try connect to external power source(AC adapter) without battery.

Later u can put the battery back and use as usual.

hmm .. Its just a try to drain the static charge from RAM slots ..which can potential cause a blank display.

Give a try n let me know !! ]


Thank you all very much.

Well, spoke too soon. The computer was working until the first reboot. Now it is back to the same thing. What happened one time to allow it to boot, I don't know. Repeating the same as above doesn't work now. But, it does say that most everything is mechanically ok. Just got to find that one thing...

The link has emoticon info inbedded in it. Here is the search term for the battery on Ebay:

NEW Toshiba Satellite L305 L355 L505 Cmos RTC Battery

My girlfriend's computer is doing the same thing. I tried the 30 seconds with no power thing, but to no avail. When I press the power button, the light comes on, but there's no HDD activity at all. I hear the cd drive actuate, and the fans come on. The hard drive is even spinning, but the access light doesn't turn on at all.

Amyc57, i had the same thing ,i had to change my hard drive and i to get the recovery disc from tobshia, i ran the recovery discs in it not the windows.I selected the tobshia recovery and just follow the instructions on the screen and i been running and don't have any problems. remember once you do this you must bring windows up to date.

I am having about teh same problem. Mine shows a screen just for a split second then it is gone. I have also noticed that if I shine a flashlight on my screen, then I can see the info that is there only part of the time. If anyone has suggestions I would love to know. I dont want to put money into this one that I could put towards a new one.
