    HI, hoping this is something I am not aware of rather than damage.

    I have a TomTom XL 4et03.

    The screen was smashed. I purchased an identical replacement screen.

    1. Before taking apart, I switched the unit on. The unit did turn on and the screen lit up, but because the screen was smashed you were unable to identify anything on the screen other than, the screen was lighting up OK.

    2. I opened the case and took the old screen out and put the new screen in.

    3. The unit turns on OK. However the screen does not turn on at all. I also have it plugged into my laptop, and the unit performed an update OK despite the screen not coming on. I did this to confirm that the unit was actually turning on.

    4. I took the new screen out and put the old screen back in, the one that is smashed but used to light up OK but was not legible. The old screen now also does not light up at all, where as it was at least lighting up.

    5. When I took the original smashed screen out, there was a white plastic bracket over the screen plug, where the screen plugs into the board. I was unsure how it operated so I took a guess. Unfortunately, it appears the exposure to the sun has made the plastic go hard so with little pressure the white plastic bracket broke. However the plug where the screen plugs in is in good condition.

    I do not understand why the screen no longer lights up, as if it is not getting power at all.

    Ok after mucking around, that little white clip you can see in IMG_5124, when I jam that into the screen plug, where it plugs into the main board, the screen starts working. So it appears that the screen plug MUST have that white clip. Only mine is broken.

    Anyone know where you can buy the white clips that hold the screen plug in?

    Thanks for the link but the problem is I don't know what it's called.

    I can't search an electronics store online or physically for a "clip of some kind"

    That is why my first suggestion was to go there (face to face with broken bit in had is still best).

    Second, if you don't want to take the time to search through an electronic catalogue take a high resolution picture of the part and sent it to them with dimensions.

    Can't see it in the photos, but IF you are talking about a white connector with a little tan latch that runs across it where the golden brown flex cable (very flat) inserts, then you've got a problem. If you raised the tan latch more than a few degrees towards vertical, it probably broke on one end, and when you try to lower it now, it does not hold in position, and the flex cable is no longer secured by it. If that sounds familiar, it's called a 'flex connector', and will be a right bugger to replace even with decent soldering skills.

    Could you take a picture that centers up this part so that I'm 100% sure I know what you're talking about, or was my description good enough above to visually match it on your end?
