    My screen started to go strange shades prior to going black. I have removed battery, then re started. The Toshiba front page opened together with black and white windows prompt for starting options from forced shut down. But that's all. Screen remains blank. Not even offering braille. Other than sticking a photo to the screen, anyone got any ideas how to fix this? Thanks
  2. Do you mean the screen is blank or the computer itself is not continueing past this point?

    Attach it to a monitor via the monitor output, and turn on. This may show tha tthe computer is indeed starting up correctly but the monitor is dieing. Or it may show a fault on the computer.

    If the screen has gone, you can purchase replacement screens. But in all fairness, it is probably cheaper to just buy a new laptop. If you get a similar one to your current machine, you may be able to just insert the HDD in the new one. Hey presto, a new laptop with no fuss.
  3. this happened to me once...had to plug it into a monitor - the computer was still working it was just the screen had gone kaput.... the advice given to me then by computery types was that I should just get a new one which I did.

    I seem to go through laptops at a serious pace...this is my 3rd now.

    The pc is fine as I can use the old desktop monitor. But that defeats the object of a 'laptop'.
  5. Maybe relevant, maybe not...

    I've got an Ericsson MC218 that died in the way that you describe. In it's case, it was the flat cable that linked the wotsit* to the screen that had fatigued to death. Your laptop probably won't have a similar connector, but the conductors in the hinges may be at fault and may well be significantly cheaper to replace than a screen.

    *I don't know what you call it - it's the half with the keyboard on.
  6. next stage is to back up everything
    & then look for disassebly instructions on the internet
    if you are lucky the internal monitor cable may have become disconnected & can be reconnected
  7. this happened to mine and the local computer repair shop put in a new motherboard for £180. Probably better to get a new one if it's an old lappy

    how old is the laptop?
  9. I had a toshiba "satellite" laptop that did this, after a quick google I was sure it was the "backlighter" which is a bulb type thing that illuminates the screen, I took it to a toshiba specialist local to me who reckoned it was the motherboard and it would cost over £400 to repair, I stuck with the external monitor until I killed it off be knocking can of lager over it!
  10. Had a similar problem, tried all the diagnostics and fixes advised on here with no luck, repair shop said h/drive and invertor £200+
    bought a new one, the brother in law loves to take things to bits, he found that a cable located in/on the hinge was faulty £10 !!!!
    Do the manufacturers preload faults do you think, set to go at different periods of use, 6. 12 .18 mths or is it just me being unlucky.
  11. I'd never get another toshiba laptop the dead screen, exploding batteries and dead keyboard oh and replacement fan. I had two of them, never again.
  12. I've been fixing computers etc for longer than I care to remember, so here's a tip for a possible quick fix. Open the laptop, and turn it on. Wait a few seconds and grasp the "base" ie, the bit with the keys on it. Now, grab the top of the screen and pull it down (not all the way so that the screen latches on the base) and flap it back and forward kind of briskly but not too hard about 10 times. While you're doing this, keep an eye on the screen for signs of life. You'd be surprised how often this works.

    Also, make sure you haven't turned the built in screen off. This is usually achieved by pressing the "Fn" key along with one of the "F" keys (the ones along the top labelled F1, F2 etc) There will be secondary functions on these which are activated by pressing and holding the Fn key along with one of these, which will have a pic of a laptop and monitor on it, or possibly a lightbulb or projector.

    Looking at one of my Toshiba laptops, the key sequence appears to be Fn+F2
  13. +1 to Saucedoctor's ideas - I can vouch for this; it's really just a crude test to see whether there's something wrong with either the inverter or CCFL tube.
    Neither of these parts should be expensive (compared to a new machine at least) and a good PC repair chap should be able to do it. Generally, good repairmen in cases like this will have glasses, beards and soldering irons on show, rather than be 17 and working in high street shops :-D

    Here's a few pages devoted to replacing these parts - they may come in handy so you can sound like you know a bit about what you're talking about:

  15. I suspect it means that you have a dirty/dodgy connection or that the insulation on the fine wires leading from the base to the lid has worn, causing a short circuit. Moving the lid has either cleaned a bit of the muck away or has moved the wires into a position where they're less in contact.

    The other thing it means is that when you take the laptop to be fixed and are told that it's going to cost you several hundred quid for a motherboard or a screen, you can show them two fingers and announce loudly in front of any other customers that they're a bunch of rip-off merchants.

    Then again, does chardy's 3rd link apply:
