Re: Samsung 23" LCD P2350 Inverter Repair

I bought a junked one of these monitors to repair (buttons light up, no image) & found this thread.

My amazement when I realised that I started it 3 years ago!!? I thought those images were rather good!

Old age and senility setting in. I hope this one is an easier issue to fix. I haven't opened it yet, so it may be the same monitor . . . Peter

I bought this dead monitor on spec on Ebay.

Found the two tiny 8-pin SMD dual complementary AM4512C backlight inverter driver mosfets shorted all terminals. No other problems visible or measured. Removed the inverter transformer, and it seemed oddly wired to me but I couldn't fault it.

No replacement mosfets obviously available in Australia, so I bought 2 IRF540N and 2 IRF9540N discrete mosfets from Jaycar, & soldered them in, held only by the drain lead. Luckily there was space for them on the solder side of the board where the originals were.
