I have a Samsung U32D970 monitor from 2015 I pulled out of the bad hardware pile that turned on and then turned itself back off after a few minutes of use and refused to turn back on. The PSU has part number BN44-00786A, and I found a couple posts about one that had blown with damage to the MOSFETs and PWM controller - but nothing about intermittent failures. I started a new thread and said that I would refresh the solder joints on the board to see if it was just a bad connection and possibly replace the PWM and PFC ICs. I then asked what my next course of action would be after those steps. I...

Re: Samsung Syncmaster 245BW



Yes, I'll be putting together a parts list of bits to replace. The 82uF cap has already been done, and I'll upgrade the resistors to larger wattage types. Though I could do with a higher wattage soldering iron. My Weller WP35 had difficulty dealing with the larger connections. Perhaps time to invest in an adjustable solder station and a DVM with a capacitance function....

Re: Samsung Syncmaster 245BW

I found this thread with a google search due to a broken 245bw I found on the HW recycle pile at work. Power light would come on but no backlight. Pulled it apart and the 82uF 450V CP803 looked a bit bulged on the top. Ordered a new one, replaced it, but still no luck. The 5.3v standby output was there, but no 5.2 or 24v output. The PFC stage was producing 390volts so that looked ok. Checked all the resistors according to this thread, and all tested good. I don't have an ESR or capacitor tester, but from all the posts, it seemed that it was most likely...

Re: New Members - please post your introductions here

Found these forums with a google search due to a broken Samsung 245bw monitor found in a hardware pile. Lots of fantastic information here. And five dollars in parts later, I have myself a new working monitor.
