Hi guys prob like me you've had lots of these cheap and nasty combi's come in faulty. Just thought I'd mention that lately I've had about half a dozen showing symptoms of inverter failure ie short flash dark screen on further investigation every one of them actually has dried or burnt solder contacts going onto the tubes. Very simple to resolder the leads back on job done ! Might save someone else the merry-go-round of popping in new inverters, checking psu's blah blah it took me a while to catch what was happening but now its always worth a quick look before getting dug in !
