LCD replacement, but not Sony or Hitachi part number

view story

http://forum.xda-developers.com – I am trying to replace the LCD screen on a 4G slide and I see there are two versions, a Sony and a Hitachi. The problem is that the part number on the broken screen doesn't match the part number of the Sony or Hitachi. I'm not sure what to do. I've Googled the part number on the broken screen and don't get any results. Has anyone seen LCD's other than the normal Sony and Hitachi? Maybe someone has a resource that would know which manufacturer this part number belongs to? The part number is: 83H00434-00. The serial number starts with: 2A4A. An y help or advice is greatly appreaciated. Thanks (HowTos)
