How did yours kong ?
No Picture at all or touch screen doesnt respond but got picture ?
Mine kong once too..touch screen not working but picture and graphic as usual.... its the ribbon ( 4 lines ) at the lcd screen that broke its connection, so no touch screen input.
What i did was :
Dismantle the ML head unit
Dismantle the LCD Panel from Head Unit
Remove the Ribbon Insulation
Apply " Circuit Writter" to reconnect the broken connection. (apply at all 4 to be safe)
Assemble back and back to normal.
Or
You can get from a Recon Unit from Ebay which cost around USD 400-500 and replace it one to one.
