    Hi,

    My girlfriend has a dell latitude 1545, she has had it for a number of years now and only since yesterday has the display starter to flicker.

    I ran Dell Diagnostics which passed the inverter test fine so I know this is not the cause which was my first thought.

    Tilting the screen backwards and forwards makes no difference and is very much an intermittent fault so at times looks perfect but then gets worse.

    Diagnostics did fail on lcd cable connection. So possibly a loose connection?

    I hooked it up to my external monitor and it displayed fine so is not going to be the graphics card either.

    I cannot think of any further troubleshooting I could have done, is everyone agreed with me that its probably the internal cable has came loose and if this is the case, is it just a fact of taking the screws out around the screen and checking the cable?

    Yes, try that first. Might need a new cable though.

    i remember when i was studying my A+ certification that there was a lot of talk about dangers opening CRT monitors due to the high voltage inside even if they had been disconnected from power for weeks... is there any risk of this with a laptop screen?

    As Sparky says *Nope* The reason being that LED / LCD monitors run on significantly lower (safe) voltages than the older CRT (cathode ray tube) monitors.

    CRTs require an anode potential of several thousand volts and because of the aquaDAG coating on the inside and outside of a CRT, it behaves like a massive capacitor and as such, would retain a charge of those several thousand volts, when unplugged.

    I've had laptops in for repair that suffered from similar flickering issues.

    In each case, some of the fine wires that make up the screen cable had broken where the cable bends and passes through the hinge assembly.
