Television Computer System

The Sony KV-36FS76U has a microcomputer system safely stored within a metal box protected from all the high voltage scanning noise of the television. It is a powerful system, which receives information from other circuits to make a decision whether to start the television. The computer motherboard is an independent module and the board slots into a socket on the main board.

The top metal cover removes easily to reveal a single PCB, and some space for another circuit next to it.

A common problem with these expansion sockets was that after a few years use, oxidation of the pin surfaces would occur causing intermittent faults. One typical fault was when you switched ON the TV; there would be no remote control functions. A common solution was to switch OFF the TV for 30 seconds and restart it. However, many people wrongly changed the remote control battery. The fault is due to poor connections caused by oxidation, and the sharp voltage spikes associated with switching ON, resulting in the microcontroller not initiating correctly.

It appears that this metal box can accommodate two panels, however there is only one socket soldered. The unused slot is marked TERR. D. Perhaps this is for "terrestrial digital" decoding that they were considering for later models.
