Hi to all,

Update on the Panasonic TR-425. The TV works well with an outboard 12VDC 2Amp stabilised power supply. After cleaning controls & switches, initial tests were done using RF input from a CCIR B/G generator & adjusting H & V hold controls for 625/50 operation.

Using the European version service manual, the appropriate locations were deduced to place the A/V baseband input.

2 RCA sockets were installed and a switch to select A/V or RF signal sources.
Photo shows location of TV/Video switch on Euro version schematic + rear panel with RCA female connectors.

TV now considered modified & operational. See a few snapshots below.
TV is on A/V input with a media player containing jpg files of vintage test patterns.

Thanks ! again for the help,

Best Regards
