go 720 screen went dim, replace?

[execdec]

Hi all. I have loved my go720 for a couple years, but all of a sudden the screen went very dim. No settings were changed, and I went through all the settings to make sure it wasn't user error.

Anyway, any thoughts on a fix? Or a link to instructions on how to replace the screen?

Thanks!

Welcome to TTF.

Just to cover all bases......

You don't have it checked to show night colours? (that will dim the screen).

You didn't somehow slide the brightness slider to a low percentage?

Your battery is charged?

Correct, all settings are good, I've slid the brightness control back and forth several times to try to "kick" it back to working properly. Fully charged. It is malfunctioning for sure.

Any thoughts on a fix? Or a link to instructions on how to replace the screen?

Thanks

There is no link here to replacing the screen as such. There are links to replacing the battery in models such as the 730 which show taking the unit apart but not specifically replacing the screen.

I'll give supermod Mike a 'heads up' to provide feedback here....

thank you!

It could be the backlight or the inverter that's packed up, best bet is to change the front screen as a complete assembly rather than the screen itself, e-bay is probably a source for a damaged x20/ x30 - Mike

You'll find that it's a piece of cake providing you don't do like a couple people have done and get carried away lifting the latch on the flex connector. It's NOT designed to be pulled full vertical. Just lift it enough to release the cable.

I assume you have tried pressing the reset button on the base of the device, I know the screen was working prior to leaving here so unless the software on the device has got screwed up the fault must be on the main PCB - Mike

hi mike - yes , i did do a hard reset, held the reset for about 40 secs..still the same issue..however i heard the tomtom drum noise and then thats it..blank screen...do you mean the software on the actual internal drive may be screwed up ?....im gonna see if i can connect to tomtom home.. or see if the pc recongnises it..

 

[mikealder]

Connect it to the PC then switch it on, use Windows Explorer to view the contents of the drive letter associated with the unit, if it is screwed up try copying your backup to an SD card and pop that in to the slot, the device should then boot from the memory card - Mike
