+Hi there 👌🏻
+
+Thanks for your fast reply
+
+Well I guess you mostly like have a C7771 broken !
+
+Well red light is a very good sign 👍🏻
+
+It is charging!
+
+I strongly recommended to misure the C first
+
+Then if you have experience in soldering
+
+Will be very easy to replace it
+
+But you need a good lens
+
+May be two soldering or hot air station !!! Be very careful with it
+
+Some flux
+
+And of course a new 330UF tantalum capacitor 2.5 V NIT 2.0 V ( old one )
+

+
+Let us know 👍🏻
+
+You are from Germany right ?
+
+To far otherwise I would do it for free 👌🏻
