I am a major fan of OCAMASTER as I have the OM-F3, OM-K5 and the OM-518Plus. You can call me for technical support if you are from the US; I would be glad to help.
I have an iPhone repair shop at Manteca but I never knew those broken LCD can be repaired. After watching the OCAMASTER's video I realized I had lost a lot of money. Everything is going well now and all those machines are easily operational.
