You can temporarily replace the led by a short.
Was the meter shorted from the start?
Did you repair the meter by opening the back or the front?
Yes it is fix and ready to calibrate, just going to do it real soon, waiting for the LED.
Here how I did it. I had to basically open the whole thing, taken the black front frame, don't try to unscrew the middle big screw, that is only for adjusting the vu needle. Cutting the securing transparent tape slowly around the meter, open it, then I open the back also since I was not certain where was the short, careful about how the small leds and wire for it, it following a specific path, you will need to put it back the same way. Then I was able to see the short, the cables inside are very fragile, tiny, so I had to do it carefully, I de-soldered the wires and added some heat shrink tubes to protect the connection. put it back together and tested, no more short.
