BT Vision customers whose television is not located conveniently near to the BT Home Hub will have been given two Comtrend powerline adapters to link the BT Vision set-top box back to the BT Home Hub. Unfortunately a small number of the adapters of one model type have a manufacturing fault which can result in the mounting holding the cover of the adapter becoming brittle and loose, resulting in exposure of potentially live mains components. Thus BT are arranging a swap out of the hardware. In the meantime users are advised NOT to unplug the adapters until such time as the replacement hardware arrives.
Update 8:20pm: BT has been in touch to highlight that it is just the DH10P model that is affected by the fault. This is the model shown in parts 1 and 2 of the updated BT safety notice page.
BT has a page online giving advice to BT Vision users located in the Products and Services. For people with the adapters who are concerned that they have not received a replacement pair already, a telephone support number is given on the page.
While BT will have little trouble contacting its many BT Vision customers, sites like E-Bay have been doing a thriving trade in people selling on the Comtrend adapters, so there may be many thousands of these adapters in households for whom BT has no way of contacting them. We could see no sign of a general recall by Comtrend, but we think in the UK BT Vision is the main seller of the devices. For those who have purchased adapters second-hand, then it would be wise to read the safety notice, and consider replacing the adapters with another brand to avoid the dangers of a mains shock, alternatively consider running an Ethernet cable to replace the adapters. Solwise and Devolo are two alternative suppliers of powerline adapters.
