Hi everybody. I have a compatibility question here. Can you interchange two Samsung T-Con boards using the same PCB but different part numbers? Let me explain.
I have a Samsung UN32F5500AF with a defective T-Con board. The board is obviously bad, with a hole in ICT1 (the center chip, just above the main board connector. It is marked LFT60B (an ASIC). Ideally I would have changed only that chip, but it seems to be a Samsung custom chip that cannot be purchased in low quantity.
I have been unsuccessful finding the exact same T-Con board. The part number is BN96-27250A (BN97-06992A). But an eBay seller near me had for sale another board using the same PCB (BN41-01938B). It is for a 46 inch TV (instead of 32 inch) and is part number BN96-27252A (BN97-06998A).
I changed the jumper resistor (located between the main board connector and the white connector) from 46 to 32 but all I get is a white screen.
Some more components are unpopulated on the original board, and some other are unpopulated on the replacement board.
My question is: Do I have a chance to make the replacement board work by switching the populated/unpopulated components between the two boards? Or the ASIC chips at position ICT1 have different programming? What do you think? Have you already tried that?
Thanks.
