Re: Samsung T240 No power. No Power Led turning on
Update :
I desoldered the IC101 & in the process destroyed the legs of it. Managed to read the marking on it using a microscope, albeit the difficulty, and Jet is right. It is marked FAN7602 although the marking is a bit difficult to see.
I managed to get 2 pieces of FAN7602C from a local store. I also bought 2 pieces of Mosfet 7N65C just in case. Replaced the FAN7602C only and monitor works well for 2-3 hours. Voltage across the startup cap, I remembered measuring, was 11-12V stable and all the secondary voltages were there. I kept it on standby overnight and when the next morning comes, the monitor is behaving as it originally came (No power LED). Sigh! I dissembled again and this time I measured that voltage across the startup cap is now 35V?!
Do you think the newly replaced IC101 FAN7602C is faulty again? Any other opinions?
