Hi,
I am trying to repair LCD monitor Samsung 2433BW,
Monitor works fine for lets say 1h then backlight goes of, usually if I turn it off and on again it works again. Sometimes it just flick backlight for second or two and then works well again.
I was assuming bad caps so I replace all except big one 120microFarad 450V, but this one is for power not for backlight,.. Board is also a bit black because of overheating. Pics are in att. I am now assuming bad transformer inverter or transistor. Can some one please give me advice how to test for bad components. I have oscilloscope and multimeter bad not enough knowledge to test them.
Thank you and have a nice day.
