I have bought a Toshiba Satellite L655D-S5050 Laptop in the U.S last year.
My laptop's screen doesn't display anything, although the lappy boots up and shows signs of processing.
I have this problem once and got it serviced within waranty period, but now the lappy's screwed up with the same display problem and toshiba sales seem uncooperative, vis a vis. they are charging outrageous service cost.
I have had enough knowledge gained about electronics and OS(I am a sophomore in Computer Science)
and have finally decided to take the matter in my own hands.
So, I request the gurus to guide me in repairing this lappy, and make some use of my hard earned knowledge and money..
it could be one of four issues. the problem WR2 was inferring to, i believe, is the backlight going out. you should be able to see a VERY faint image of the desktop if its the backlight.
Can you plug a monitor into the laptop to see if the screen is displayed? If you get a display, that will rule out bad graphics chip.
It could be the cable that connects the LCD to the mobo and routes through the hinge came loose or is bad as well.
Or you could just have a defective screen
The quickest way to change the display output settings is to use the
display hot key (Fn + F5):
1 Press Fn and F5 simultaneously.
2 While holding down Fn, press F5 repeatedly until the setting
you want takes effect. Briefly pause each time you press the F5
key to allow time for the display to change.
This hot key cycles through the settings in the following order
(the last two options are available if an external monitor is
❖ Built-in display only
❖ Built-in display and external monitor (simultaneously)
❖ External monitor only
❖ Built-in display and TV (or other external video device)
❖ TV (or other external video device)
❖ External monitor and TV
❖ Built-in display and external monitor (extended mode)
❖ Built-in display and TV (extended mode)
❖ External monitor and TV (extended mode)
❖ Swap-Switch primary display between internal display
and external monitor when using extended desktop
Ok the key is Fn + F5 cycled 3 times for external monitor. the external monitor will be this pc, so i will be offline for like 10 mins. Any pitfalls I might face during the "External Monitor" phase? Or what information should I note down before reporting back.
either the cable/hinge or the lcd is shot. the cable is seated into the motherboard and into the LCD panel. It can come loose and cause the problem you are having. Since the cable runs through the hinge, ive seen it fray and get cut as well.
