Re: Sharp Microwave - no backlight

buy the guy a new oven then.

there are lots of things that fail in microwaves that arent related to the high voltage capacitor.
newer machines may not even have one if they are invertor-driven.

I don't mean the voltage.... i mean the housing... u'll never now if this thing is closed as it was before.... there is radiation inside... thats what i meant to say... take car...

Re: Sharp Microwave - no backlight

the radiation is in the oven cavity, the only times you need to worry is if you mess with the magnetron or the door seal.

the back of microwaves is not sealed/screened

Im aware of the dangers, but I wont be touching the megnetron. I only need the keypad/lcd pcb. I've opened it before, 2 years ago, but I didnt have time to fully examine it.

Re: Sharp Microwave - no backlight

So I found out what the problem was. 1 LED was blown, creating high resistance. Took a long time to desolder the LCD Screen. Got there in the end.
I ended up replacing ALL 10 Green LED's with Bright White LED's. LOL.
Works sweet.
Thanks for all who chipped in to help.

Re: Sharp Microwave - no backlight

replacing all 10 was a wise move,
i found that if you replace an led in anything the brightness/colour usually doesnt match the old ones
