Hi
I received direct from China today my LCD 3.5" display, but it has stopped working! It had been working for about 10 mins but exhibited a horizontal line ripple effect at regular intervals of about 10 seconds. Now screen is blank after very briefest of flashes. I have contacted seller and probably will want a refund rather than a replacement item.
I open the back panel to have a look at the circuit and was surprised to find that it wasn't fuse protected (picture below).
I had the item wired up via a splitter with two other devices powered from an unregulated AD/DC adapter output 12v 2A. I have tested the adapter and its outputting 12.12v.
Device 1: DVR
DC 12v
<= 250 mA
Device 2: Camera
DC12v
Max. l30mA
Device 3: LCD 3.5" LCD display
DC 6v - 36v
250 mA

The resistor (105) to the right of the 12v+ looks a little messed up.
