Hi @tirthasarkar
Not sure if they will work as all the models you mentioned are used with NTSC system whereas the SR7 is PAL system i.e. 525 lines vs 625 lines so perhaps the screen connections may not be the same and it won't work or it won't interpret and display the video signals the same.
Is there a Sony part number on the back of the LCD screen? If there is and if you haven't already done so, try searching for that.
