If you can't find the board or part, that's the end. If you feel it's just the IGBT transistor then why not scavenge that from any board that uses that part?
Here when I search I use google (natch), ebay and shopjimmy.com. Craigslist too.
I am from India and new to the forum.
After 5 years of service my 51 inch Samsung plasma TV broke down,no activity after power on except the red led.Samsung technician checked and said portion of Y board is short circuited,isolated Y board is not supplied by Samsung but it comes with entire screen costing INR 25000(around 340 US $)!!.
I took out the board and checked it myself.One rectifier SF10A400H and three IGBTs all FGPF4536 show shorted pins.I checked on line for replacement of the board but could not find one.Y boards of different models of Samsung are available on amazon.com and ebay.com .
Can any one help finding a new/working Y boad or repairing the board.In fact more parts may be shorted and the shorted rectifier and IGBT transistor is not available online in India.Any idea about their equivalent replacements?
