In 2009 I bought a new TV on digitec and brought it to my mother who lives in Cuba. Now the TV broke and the diagnose is a broken tcon board. I called digitec and Samsung Switzerland and they won't sell me the part. However, they said I can bring the TV to them for repair but the TV is in a different country
I have the exact part number, pictures serial number etc etc but can't find it anywhere. Already Googled to exhaustion and searched over ebay different countries etc etc. The only exact match was a chinesse guy listing an ebay item with the exact model and serial but he requires you to send the defective part first (after asking, I figured he simply fixes it

)
Can anyone advice what to do?
UPDATE: another question, does anyone knows the Samsung standards for these tcon boards? e.g. the one that I'm looking for is:
- TV Model: Samsung LE-37B530
- TCON Board model: 55.37T04.C31
- Sort of a serial imprinted in the board: T370HW02 VC CTRL BD
- Serial with bar code: TT-5537T04C31-93D-M930117-01698-07
When I look in ebay I find very very similar tcon boards with the exact #3 but slightly different #2 and #4 e.g. TCON board model 55.37T05.C09 does anyone know the compatibility rules? would this one work? is the #2 the important bit or?
