Fully | TV was with both fets QS802C and QS801C: MDF9N50. It replaces the two with 12N65C and the two exploded at the time by burning the resistors and SMD diodes at the bottom of the plate, even after their TV was replace the TV and oscillating the 15V. Measuring once again I came to the conclusion that CI ICS801 was defective. Trading everything solved. | Defective components/ check before replacing the transistors: DS821 and DS820 (A4W39) RS804 and RS806 (20R), RS808 and RS809 (10k), DS804 and DS805 (KL3) and CI ICS801 UCC25600 | Pedro Igor - Eletrônica Portugal |
