Charge 5 black screen, only working when on charge, not synching

[llllaura]

Hi all,

i bought a charge 5 in april and yesterday the screen suddenly went black. it wouldnt turn back on no matter what i did. so when i got home i plugged it in and obviously it is now fully charged. but when i unplug it it goes screen black again. still says its fully charged though. i did the 3 second button reset and a device reset on the watch itself - neither worked. also when i try to synch it the app doesnt work and there is a red "!" next to the synch button. pretty disappointed in this to be honest as it seems to be a common problem . has anyone worked out a solution other than simply getting a warantee replacement?

it only works when it is plugged in

Mine has gone black also even when charging. Won't sync. Tried pushing the button on the charging cable three times. Reinstalled the Fitbit app. Restarted my phone. I guess I will have to try calling someone tomorrow.
