These little sets can be surprisingly easy to work on.
When apart they look kinda stepped on. Just be careful not to
stress wires wires between assemblies & keep things from touching.
Depending on you knowledge level & your equipment it should
go OK. A service manual is the next step. Without one what you ( and I )
can do is very limited. Post the model number next & maybe someone
has it.
