A Visione VISDVD5820 DVD player came in for recycling and since it has a HDMI output I thought I may as well have a go at refurbishing it. They are budget brand and as we will see you really get what you pay for. It seems to be a brand name used by Harvey Norman.
The batteries in the remote had leaked and caused really bad corrosion on one of the battery terminals to the point of almost completely rusting the retaining spring! Also, there were splatters of solder left on the circuit board from when the battery terminals were manually soldered in place in the factory.
A quick internet search showed that this fault has has happened to others. They sold for $29 and $18 and as low as $9! There is no point doing any repairs on it so off it goes to be dismantled.
It is a shame that this sort of poor quality equipment with poor quality batteries is being sold. This sort of stuff is short lived enough as it is because of the rapid change in technology.
