Samsung Galaxy S3 Display problem
 
Dear everyone,

I have a Galaxy S3 with display problems. Have put a brand new complete LCD unit but there is no back light. The LCD is fine as it has been checked on another phone.

Any suggestions as to what to try?

Many thanks,

Kris

search for the replacement components type's and models prices from china you will get many website you can use....and ask for the replacement conponents to be shipped for you ....but for me i suggest that your replacement components to be taked from a dead or broken mobile cause most of components are original and it will work definitly ....
i hope that will help you.

Same here, I thought it was from the display connector of the main board, but it was exactly from these elements.

shivanesh try, if you can, another display maybe is the flex cable of the display or the display connector (on the flex or on the logic board).
