Inno-hit tablet repair

A colleague asked me to try to repair his tablet, an Inno-hit IHA C0707A.

The tablet had a problem with the power switch, moreover the internal speaker wasn’t working.

After having opened it, I noticed that the speaker’s wires were disconnected from the main board and the power switch was broken:

First I tinned the wires and soldered them again with the correct polarity (luckily on the main board was clearly printed which was the positive contact):

I sourced from Aliexpress an SMD switch and I was able to find the exact model… after a couple of weeks I receive the envelope with 10 switches:

tablet-5

So I removed the old, damaged switch and replaced it with a new one:

tablet-6 tablet-7

When I closed the tablet, everything worked fine!
