My printer's power supply failed and I found a shorted FET, open resistor, open 1N4148 diode and a sm resistor on the solder side of the PCB burnt beyond recognition.

Does any one knows its value. It is right under the filter cap C5: There are 3 105R, 2 334R, 1 124R and one missing. The PSU is an ASTEC model AA20550, PART # C6426-60081.
Please help it is my only printer and i need it

    Can't give a cost on it, it's a part not available. Even if it were I'd venture to say it would be too costly. Small printers like this you're better off replacing the machine.

Oh and your pictures didn't show, site doesn't allow attachments but you can use a site to upload them to & post the links for them.
