When pressing the power on/off button, the display turns to the lw-band, there is no sound, there is no response to any button and she switches herself off after some 10 seconds

This is a reasonably easy method. Turn the unit on and press the 'Tuner' button to turn the radio on. Quickly press and release the + or - button once. The frequency number on the display should move up (+) or down (-) one step. Repeat pressing the button until you get to the station you are looking for.
The size of the step is different depending on which band you are on, FM will be bigger steps compared to LW and MW.

Hi, Your post/description "the frequency increases in steps of .2 Mhz or 200Khz" refers to the increment of frequency spacing between tuning steps and is largely dependent on the radio standards of the country/region the radio is intended to be used. Assuming no hardware fault to the radio, tuning steps may be adjusted by: 1. With the radio switched off, press the Step/Band button for about 2 seconds. This will display the current FM tuning step (200Khz as in your case); 2. With the radio switched off, press the Step/Band button for about 10 seconds. This will display FM and a blinking 50Khz with a single beep sound. By rotating the Tuning Control you can increase or decrease this value. 3. pressing the Step/Band button again will move you to the tuning increments of the AM band again adjustable via the Tuning Control. 4. pressing the Step/Band button again will save the setting and complete the process. Hope this be of some help. Good luck and kind regards.

No, it uses the same source.
Have you checked which band you are selecting? It has 3 FM bands, LW and MW, right?
It may not be a relay, but an untuned station.

Remove battery and disconnect from power for 5 minutes, also remove map card, this will reset the device. Try it out

To only way you can fix it is taking apart the Tom Tom, checking if the flat ribbon cable and connector to the screen are well in place and eventually replace the display ($80 on Ebay).
Unfortunately this will invalidate the guaranty, and you risk to damage your GPS if you are not a really experienced DIYer. Tom Tom offer one year full guaranty on all their receivers.

Hi again, Seems you posted twice. A copy of my reply to your other post.... Assuming no hardware fault to the radio, tuning steps may be adjusted by: 1. With the radio switched off, press the Step/Band button for about 2 seconds. This will display the current FM tuning step (200Khz as in your case); 2. With the radio switched off, press the Step/Band button for about 10 seconds. This will display FM and a blinking 50Khz with a single beep sound. By rotating the Tuning Control you can increase or decrease this value. 3. pressing the Step/Band button again will move you to the tuning increments of the AM band again adjustable via the Tuning Control. 4. pressing the Step/Band button again will save the setting and complete the process. Hope this be of some help. Good luck and kind regards.
