No image, with sound and back light working. | Shorted capacitor CD25, on the display board (tip of the board). | I lowered the circuit current. I added a 4r7 resistor in series to r759 (4r7)(underneath the board), on the inverter. the measurements were 238.2v and 131ma, with back light at 100%, for 229.8v and 99ma. | Eletrônica R-Tec |
