Question about Toshiba Satellite 1805-S204 Notebook

1 Answer

I have a Satellite 1805-204. I powers up and the screen will intermittently stay on. If I tap the sleep button the screen will display for a few second then go black. sometimes it will stay on for long periods but one never knows. Does this sound familiar? I'm told these are infamous for this.

This could be a faulty video cable or connector or CCFL lamp or inverter.
Try reseating the video cable/connector that connects to the motherboard first.
If this doesn't work then to determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

TV turns itself off?


I am sharing four cases in which your tv either turns itself off or appears to turn itself off.

TV appears to be off
  • You using your tv as a monitor or your pc is in sleeping mode.
  • Your cable or satellite Box is not outputting a signal.

TV turns iteself off
  • The sleep timer is set.
  • The off timer is set.

Your tv appears to be off:

If you are using the tv as a monitor If you are using tv as a monitor and the stand-by light only
blinks for a few seconds when you press the power button,your pc is in the sleeping mode. To take your pc out of sleep,press a key from your key board or move the mouse.Tv turns on.

If you are using TV with a cable or satellite Box

If you have a cable or satellite Box your Tv may appear be off because the cable or satellite Box is not outputting a signal.Press the guide or info button on the cable or satellite Box remote control.

if the screen displays info or guide data,the problem is caused by the Box,you must call your cable provider.
if screen does not display info data,change the source on your TV.

This past week I havent been able to put my Toshiba into sleep mode. It's a Satellite Model# A215-S4747.


Try removing the battery, removing the RAM, leaving like that for a few mins, and then put back the RAM, carefully, and the battery, connect to power and hold your finger on the Power Button until it boots, then go into the Power Settings properties, and set your "Sleep" and "Power Saving", & "CPU &Screen" settings from there. Reboot and now you should have your sleep function back.

Screen stays black on startup of toshiba satellite L300


have you tried either switching between external and internal monitor usally Fn + F5 on toshiba or try plugging a monitor into the back and see if it displays.
if you get a display on the external monitor then its probably a screen or inverter fault if you donot get a display to an external screen then it is likley t be the graphics on the board itself.
hope this helps

Hit the keyboard keys. It is better to just turn sleep and hibernate off and just use a screen saver or tun it off.
