Hi . I have this transformer and pcb board is broken . I cant use switch to put it on 220v input . I will be thankful if help me how to run it directly . It has 6 pin . I need to know where to connect N An L also if i need to bridge between pins to put it on 220v mod . Thanks
It works . Thank you my friend .
I have a sharp md-xv300 . Its transformer is dead . I replaced with a Panasonic transformer but its 110v i need to use converter . I wanted to replace with a 220v transformer . I have two 220v . First one has same voltages like Panasonic that i replaced but as soon as i put in in power one diode and fuse burns . Pcb is for original sharp is it possible its diodes cannot handle 12v from 220 transformer because it has more amp ? Is there any solution because ac voltages are same

Hi again . I solved the problem for burning fuse and diodes . There was a bridge between 2 ground of hi voltage and low voltage of output . Cut it and know it works . I have another problem know . Screen of my system powers on a single ac cable i don't know which wire is its pair and don't have schematics . When i connect it to opessite 12v ac it turns on but it make noise . I disconnect it and sound is clear . Dont have any other options for screen i don't know if you can help me about this problem its kind of complicated . But if you help me run little transformer on those schematic maybe i can get another source of power for screen . I mean 220v inputs of small transformer. Sorry about my. English and thank you . You help me back a system that i loved . I wish you best
Hi . Yes my friend . As the pcb is broken i cant find out second transformer (little one lower right corner ) how works on 220v . thanks to you Big transformer works greatly and i ran my amp but i have noise problems when i get power for filament maybe with additional power source i could fix it . Just need to find out witch pins are for 220 or like last one i need to make a bridge . 🙏💐
Exactly i mean second transformer . Little one lower right . Sorry my English isnt too good . About screen i mean vfd lamp that shows equaliser and volume......when i connect it lots of noises makes . If i couldn't solve that i put a switch on vfd screen after playing music i will turn it off manually . Also volume and key working when vfd is off
Hmm, without any schematics it appears to be difficult, for not to say impossible to solve your issue.
Best regards!
