In PSU, on the secondary side of switch supply there are electrolytic capacitors: for 13 V is 470uF/25V and for 5 (and subsequent 3V) is 1000 uF/16V. Those capacitors in some devices from this series use to break (why? I don't know: maybe cheep quality). Check voltage on rectifiers outputs with oscilloscope: if there are not constant voltage on one of them you should replace it with the new one (of course good quality). I've got the same failure subsequently on 5V supply (this reparation was done by LG service, but when I asked them they answered they replaced mother board - bull shit!) When the same "flashing" problem after guaranty occurred again, I had found soldering traces on the cap on 5V!And guess what - it was cap with a different brand than others.



This solution is maybe only for el-geckos, but no service wanted to repair my quite new, still worth something projector (not in Sweden any way). If you can’t do a job your self you still can ask some handy friend which know how to solder parts. Be careful! There is high, dangerous voltage on primary, so you must know what you are doing!



I'm sometime very irritated: that capacitor cost less in bulk than 2 cents each! But the ordinary people must buy a new projector because of lack of service!

Your MacBook should recognize the default file system already used to pre-format the LG extenal hard drive at the factory. You'll be able to write and read from it without issue. In fact, if you intend to ever also use it with a Windows machine, using it and leaving it in its pre-formatted state is recommended. As a novice user, I'm imagining you'll use the external drive for file storage. You'll only need to format it specifically for your MacBook if you intend to use it for more specialized MacBook tasks (like using the built-in Mac backup utility). In which case, the instructions to format it for Mac is available here - Format an External Hard Drive or USB Flash Drive for Mac OS
