instructional video showing problems encountered getting a NEW raspberry Pi B+ computer working properly . Problems were encountered with connectors not making good connection the USB connectors, HDMI connectors and micro SD connectors all had intermittent connection due to dust like material in them .This is a NEW unit and was wrapped in the original packaging . Use of contact cleaner or Alcohol to clean the connectors is recommended. Note ! Some connectors may not be cleaned with a little piece of cardboard and contact cleaner or alcohol such as the HDMI connector so a tiny bit of contact cleaner should be applied to the connector itself using a toothpick or similar and the connector engaged and removed several times to wipe the contacts clean . Good quality gold plated connectors are of course the most trouble free when it comes to intermittent connection . see video . 73 Bob
