Heating until the bu808dfi horizontal output burns out. | This TV heated the horizontal output a lot even though I replaced it with other similar transistors, the defect remained. | Connect two d2539 or 1803dhi transistors in parallel, connect base to base, collector to collector, and emitter to emitter. preferably place it on a heatsink. Even though they work with temperatures that don't exceed 50° and that's it, the TV will never have any problems in this place again. | MARCONES DE ARARIPINA - PE |
