Led question about 1620

#1

My Benq 1620 OEM@ Retail blink the led (Red, Green, Red) some times when I burning a DVD this is normal with this drive?

Thanks


#2

YES

On upper window you see white line with drops this is when led is changing from red-> green -> red



#3

I’ve asked this before but never got an answer. My 1620 flashes red and yellow for a split second then goes back to green. I was told this is normal but my question is what does the red and yellow LED mean?


#4

Red means is burning and when it flashes yellow in between its just part of the process. Nothing to worry about.


#5

Is the yellow perhaps the WOPC in action?


#6

If it blinks yellow to the end of the burn it may also be BLER OPC (Block Error Rate Optimal Power Control).
Pick whatever suits you best… :wink:


#7

So I think it’s WOPC. I got the information that during writing the burner
with WOPC enabled pauses for some nano-seconds. It makes sense with
yellow for short breaks. I tested when I got my first 1620 with WOPC
disabled. There are no breaks during writing process with the yellow led.

Thanks for the answers! I meant to say it flashes yellow and green then goes back to red, sorry if that confused anybody.
