I've never had the experience with repairing the TT but I guess if you can read the chip's manufacturer and id that you could call your electronics store and ask if they have it or can get it for you.

I know I tried to find the integrated Samsung chipset of the GO models as a possible replacement for the one in my XL-S and could not find it for sale in unit quantity when using Google for a couple of hours...

Unfortunately since the chip is toasted, you can't read a P/N. It looks to me like that area might be the oscillator section or clock section since it's protected under that metal cover.

Maybe someone on the forum has taken their's apart and could get a P/N for you. What's the exact model number of your unit?

AFAIK, from reading all kinds of forums for many years, employees would be forbidden to participate in any forum. Manufacturers are paranoid about their secrets being revealed or that some information would lead them to court. Recently, a TT support employee posted a few messages and was dismissed the next day for having done so...

Back in January, when I started my interest in the TT, I ended on a European TT forum board where there was a repair facility. I guess if you try a Google search for ?tomtom repair? you could end up with the reference. But your real problem, if you wish to repair it yourself, is getting the part. It may be common or it may be custom made. If the latter, good luck in getting it...

Keep us posted as I'm sure many would benefit from knowing about how it turns out.

Please do. Repairs are often too expensive to have done at commercial facilities as they charge upwards of 50$/hr and one needs to earn over 75$/nr to compensate and I'm not even close to that income. Indicate where you were able to find the parts as this is often the most difficult aspect to a repair. You could also go to the Samsung web site to get some sort of schematics on the integrated chipset as I only got the general description of them.

Hi All.

This is Linear Technology chip LTC3411. This is DC conwerter. You must change this chip and chip AIH TPS62000. Becouse two are always bad.

Best Regards.
