toshiba l655d-s5050 black screen

May 12, 2013 at 10:51:47
Specs: Windows 7
I have a Toshiba L655D. It was working and then went to a black screen. On start up the fan works and the Num Lock and Caps Lock lights blink on then go off. I have tried battery in/out; power cord connected and not connected; F8,F12,0, all on start up; Control/Alt/Del; tried playing a DVD; nothing comes on the screen. I have restarted it 20 times or more with all the different variances. I don't currently have a 15 pin connector cable to go to another monitor, but I feel that without the start up lights working that would not change anything. Is there anything else out there that could be tried. The MB is half the price of another computer so if that is the case then I am DOOMED. Help is greatly appreciated.

As you never see anything at all on the screen it is almost certainly a hardware fault.

There are many possibilities - PSU failure is possible. Not easy to prove from afar unless you have spares for substitution.

Always pop back and let us know the outcome - thanks

If PSU means Power Supply I just changed it a bit ago. The charge light does change from orange to white.

Check Adapter and battery connections.

"Sometimes" this helps:
Unplug the power and remove the battery. Hold power off/on button down for about 20 seconds then reassemble and try again.

That was part of my earlier attempts, however, I tried it again and received the same results. The start up lights( Num lock and Caps Lock) just blink on and then right off. Just for a split second. Thanks for your input.

Just connected an external monitor cable and got nothing on start up. The fan also has a slow start- pause- and then speed up sound.

That's not unusual.

If nothing happens using the above methods, it may have overheated because of dust.

I will have to look at these later, however, the fan has great air flow and nothing in the vent holes.

I had this same problem...try wrapping the laptop in a towel and get it warm. There is two possiblities...microfractures of the motherboard or a bad update that caused stuff to go haywire. I got my video back up with wrapping it in a towel. I currently backing everything up in case it's the motherboard. I'm also checking if it was an update cuz my computer applied an update on shutdown and then i had no video when i tried restarting.

I've tried everything but finally resorted to the towel wrap. After heating up you have to let it start cooling while continuosly pressing start button. If you don't shut it down it will stay on for alittle or a lot of time. Once you shut it down you have to go through the same procedure. Seems and looks like a cold solder joint. This is one month out of warranty. I also have a high end Qosmio that has gone south. Toshiba support has gone south also. My last Toshiba product ever and will relate to fellow geeks.

I can understand why you say this but I sometimes put it down to bad luck because I've seen the exact same thing said about other manufacturers products. My wife has had her Toshiba laptop for years without a hint of trouble - used daily.
