Thanks for that it is a RTM-684
Changed the resistors and the unit is still in standby.
dowie is the 5 volt rail actually 5 volts? put a cro in it, change the electros in the primary and look at the 1000uf on the secondary of the startup supply.
those 2 resistors always go black but they still work ok.
your troubles are further down the supply chain
member. Austech dog squad: if it can be fixed the dogs will sniff it out
Thanks again Blue Dog it was the 1000 Uf 25vold cap in the secondary Thanks again.
