If you want to peek into consumer or any electronics.. probe with a signal analyzer for the usual suspects: RS-232 (TTL-levels, CMOS-levels, and serial-levels), JTAG, SPI, and I2C.
First, probe header pins and test points (rows of pads not meant for components) before probing around other components.
PSA: If you're designing a PCB for hand-testing, save money by eliminating connectors with tag connect plug of nails. They're also compatible with automated board testing.
