Actually at the beginning the backlight was on but no display . Unfortunately I tried to fix the problrm without disconnecting battery then something it may be fuse or register burn and then there was no light nothing , i thought the motherbaord dead . its new phone in the market so I was afraid but I just made jumper then it came to previous situation like bacllight on but no image in the display ..........Three days I tried without success but finally it iw working with your solution .............Thousands thanks to you

Yes, do exactly the same jumper on this fuse near the LCD connector.
Works!

Very good solution. I have tested all filters and condensators but not this little guy. Nice theard. 👍👍👍

I have a working Display but no backlight after screen replacement. For z3c the fuse was marked with a V according to some internet sources. Is it the par also marked with V on your photo? What should I let it replace with? Bridging would not be my preferred solution as it might have a function which apparently has already been used :-)

Thank you very much!

It works!! Thank you

Just took my 5€ multi meter and checked the two devices marked with L and V. While L gives me a resistance towards 0 ohm, V gives me infinite resistance. So apparently this is the fuse responsible for the backlight on Z5 Compact. Is there an exact replacement? Somewhere else I read that a 0 Ohm 63mA resistor would do the same job.

Thanks

i am more interested in that one with "L".
can it be replaced by some similar component from, for example an Z3 compact donor board, which i have here?

i tryed first to brigde the L and A fuses, because no backlight and it worked, i got the screen back on, but then i noticed this issue:

Fehler - Sendvid

if the lcd is off, for few minutes, or longer, after i turn it on again, it shows those strange green issues for few seconds and then the green color disappears. the display is working normaly and those green issues are not showing again, while lcd is on. if i turn it off and leave the phone for 10 minutes again, when turning the lcd back on, green issue are there again.

then i took V fuse from my Z3 compact donor board and replaced the brigde on the z5 compact board with it. no changes, i still had the green screen issue...
then i took the second V fuse from Z3 compact board (the one for the vibra), replaced the other bridge with it (those one where originally the L fuse was). lcd and backlight still working, but i STILL have the green screen issue!

now i am out of ideas... is maybe some other component faulty? or do i really need that L fuse, to get rid of those green "things" ?

any help would be appreciated!

Do anyone know what fuse to jump for a no backlight issue on Z5 ?
Because after screen replacement i can see Display working but no backlight after screen replacement.
