Phone 1.
When the phone is switched on it is very dim.
You can just about see the operator logo etc.
I have checked that the brightness is 100% and it is.
I have carried out a master reset but still the same.
I have fitted a lcd screen that i know is ok but still the same.
I have flashed another display driver but still the same.

Phone 2.
No sound from speaker.
Mp3 will play a track no problem with headphones plugged in but as soon as you remove them all quiet but the track is still playing.
When the phone receives a call it will only vibrate.
When i do a service test the speaker is quite but earphone is working.

Please advise what i can do
Thanks
For the 1st phone solution, you need to repair the backlight section (mostly backlight IC)
and for the 2nd solution, try to upload original acoustic driver for your phone and post result. hope it will help you solve your problems.
