A1398 Backlight problem after Speakers Replacement

Hello Guys,

a month ago i decided to change the speakers by myself they were in a bad quality , everything was well i changed them also i found some dust on board and i clean it with alcoholic paper and a hair dryer o Warm air i assume this is the problem,

after reinstalling the battery and the cover and booom no screen but i hear the chime that means we have a problem now is with the screen , days after i heard about the backlight problem i light the flash from the back i can see the login user , i tried an external screen and it worked , now and since a month i’am always using it with external screen, imagine when i go anywhere always looking for a tv to use it , i took it to a reparator he said 600EUR just for backlight problem !!

now i would like to confirm where is the problem exactly , i attached some pictures maybe one of you can help and see the bug , i already changed the lvds cable to check but it wasn't the problem so it’s might be lvds connector or the fuse ? and what i need to fix it

Sounds like your repair did more damage then fixing things ;-{

wiping down a logic board with wet wipes is not a good idea more so if you still had the battery plugged in. To add to it you used a hair drier which could build up a static charge (ESD) and if the drier touched the wrong place you could zap your logic board.

Time to find an independent repair person who has the skills and tools to repair your logic board.
