    I've been connecting the same laptop to the same tv with a vga cable for about two years. All of a sudden, I'm getting "no signal" from the TV end. The computer is definitely recognising the computer as a monitor. Dell laptop Windows XP, Toshiba LCD TV. Any ideas why this might have happened??

    laptop gone to sleep? Press the pwer button on laptop for a couple of secs, to turn it off then reboot.
    Check cables

    If you search google for 'mating cycles' of a vga connector, the specs are often only 100 cycles.

    ie. the connector is only expected to work properly for up to 100 times (plug and unplug =1 cycle)

    so maybe the cables broken...;)

    SET resolution to 1024x768,
    refresh rate grahics card to 60mhz.
    Reboot pc, see does image appear, on tv, make sure pc is set to output vga.

    SEE can you see settings in graphics settings advanced ,tv out .
    I dont think theres any limit re how much times you can plug in a vga cable,
    What tv are you using,eg sony 560j what os is on the pc,
