Dear all,
I replaced leaked old fly back transformer with new one and also horizontal output transistor of my LG 21" flatron CRT TV. But it was blown when I powered up. Without H-OUT transistor, 75 W and 60 W light bulbs are parallel at B+ and ground B+ has 112.5 V and big capacitor has about 320 V. Horizontal drive transformer has not short between primary and secondary. I replaced HOT again and turn on the TV without yoke and degousing coil the TV was on with series 75W light bulb. But, When I connected only yoke and powered on, again HOUT was blown though there is the series bulb. What may be the problem?
Thanks
