This is the view of Roberts PGC-FX203K rear memory socket.
A close up of the faulty solder joints.
As you can see from the picture the two end pins have bad soldered joints and this is causing the intermittant boot problem.
Robert asked Sony to examine the memory socket for faults but Sony denied that their was any manufacturing fault.(You can make up your own mind).
Thanks to Robert for the picture.
If you have any queries about this or any other Sony machine faults then let me know. Bruce Benson
