    why 18 V shouldn't it be 12 V like the input or even 4 V like the converter power IC

    The problem is i don't think i can find such part locally.. Need to put something else which can do the same like fuse or zener diode What do you suggest. I'm sure i can find such part locally. I have an old pc power supply but i doubt i can find same part in it Also to remove it do i need hot...

    now it's working fine i connect new C1 it didnt fail or get hot..i think it all was because i used wrong D5 when i used the original 1N5819 now every thing working fine i really learned a lot from this project about the used diode and how this circuit work a lot of thanks for every one who help...

    it's test were 192....in your last pic you send in reply #54 D5 is D9 done that done that still no glow when i connect the power done it work fine without heating or blow up and the DC voltage measured being across C2 is 294 Vdc nothing no glow a all it work fine C2 didn't fail or get hot...

    sir 73's de Edd there's something i would like to take you opinion about D7 and D9 both are 1n5819 diode D7 was giving me like ± 300 on diode scale so i change it but i changed it to regular 1 amp diode and now i learned that 1n5819 is a schottky diode do you think the new regular diode is...

    D7 give me those readings both way on diode scale in multimeter 1360 red for cathode 650 black for cathode didnt try yet sir 73's de Edd changes will do it in while and see what will happen

    1 is brown , 2 is blue red lead on the capacitor first ohms scale 2M + 2 = 1.3 + 1 = overload - 2 = 0.7 - 1 = overload red lead on mains input 2 + = 0.6 2 - = 1.17 1 + = overload 1 - = overload

    i measured them on the Diode scale inmy multi-meter not with ohms scale do you want me to measure them on ohms scale ?

    well you know the brown doesn't have to be the positive hot line evey time since it could be connected to the (-) ~AC power supply which is 220 ~V in Cairo so you want me to 1- connect the lamp between the brown wire and the board any way? 2- connect the lamp between whatever wire blue or...

    overload it give me 1 which mean overload will try one although the fuse says 250 V fuse ok will check that and get the result

    yes the 4 been replaced with 4 new diodes 1N4007 D3 = 628 D4 = 675 D1 = 577 D2 = 595 they were 1N4007 and i replaced them with 4 new diode 1N4007 D5 i didn't touch those diodes at all or change them..do you think i should replace them as well? i only replaced D9 the old one had number RL...

    C1 FAIL again as you can see due overheating C2 dc voltage were like + 250 dc volt Couldn't measure C1 because it fail Will replace it with new one

    in one minute it get so hot and boom have digital multi meter i test the C1 one on 200 AC voltage the multimeter start with 170 ~V then decrease to 37 ~V then decrease stay at 5.5 ~V the C2 is the same stay at 5 ~V
