Question about Tomtom GO 910 GPS Receiver
The green light is on and we have it plugged in but nothing shows up on the screen
I had a similar problem after I fixed the top power button on my Nuvi 350. I had dislodged one of the tiny ribbon cables connecting the screen (in my case it was partially dislodged so the problem was intermittent).
Your problem could be different -- the screen itself could be damaged or something else could be wrong. Try the obvious first -- like the reset button on the back. ;-)
If your problem is like mine, here's how to deal with it......
First of all, the best instructions I've found for opening the unit are here:
I added to that thread some tips at the end, because though the instructions worked, I had a couple of minor tribulations following them - hopefully what I added will save some time.
Once the unit is open, note that there are three orange colored ribbon cables in the unit. DO NOT CREASE THEM. These are quite fragile.
One is for the antenna, two are for the touch screen. I think one is the "touch" part and the other is the "screen display" part, but I'm not sure.
These connect in a tricky way. There's a very narrow flip-up latch that runs the width of the cable right where it connects to the board. This is hinged like a piano hinge and can be flipped "up" carefully. The hinged side is away from the ribbon cable. You can carefully wedge up that latch and then the ribbon will slide in and out under it. Make sure the ribbon cables are slid in carefully but fully and evenly. They go in further than you might think. Then, keeping the ribbon cables well seated, close the hinge.
If you force things and it breaks, you're going to destroy the unit (unless you're MUCH better than I am at soldering on a new connector to the board). You might want to try using a pencil eraser to push that hinge closed as it has some give to it.
If you've never done anything like this before, consider the following general tips:
1. At every (and I mean every) stage, take a digital photograph of what you're doing. If you forget how it goes back together, you can look at your photos. Take way more photos than you think you need. You will not remember what you think you remember.
2. As Robert Persig once advised -- the most important thing is a comfortable place to sit and good light. In other words, take your time and enjoy the process of learning and doing it. If you try to rush or get frustrated, you'll do poor work.
3. Don't force things. They break.
4. If you fail, you're no worse off than when you started -- since the device is useless right now. If you succeed, you'll feel really great about it.
Best of luck.
