Hi,

after repair of my Genz Benz Streamliner 900 (Blue LED failed) in april this year, the LEDs failed again 2 days ago, came back yesterday for about 1 hour, then failed again.

Is there a connector inside which I can check?

I dont want to give it to the repair service again for two weeks
since we have gigs coming.

Thanks

Volker

Sorry to hear about this. PM me and I will take care of it for you personally. Turn around is only a day or so. There are no connectors involved.

Hi,

since in germany there is no quick repair possibility, I decided to keep the Genz Benz without LED light, until i can afford to give it away for 2 weeks.

Now,
what happens is that after playing for 2 hours or more the LED light comes back, and stays lit for the rest of the gig as long as I do not turn off the amp.

After turning off and turning on again it is dark inside... until I have played again for some hours.

This I have seen now for two times.

I do not really believe it is a bad LED.
A LED is working or dead, nothing between, as I was told.
Could it be that the PCB has a defect, and when the amp is warm inside,
a broken line on the PCB (dont know the word for Leiterbahn) is expanding and then the
LEDs have connection to power again?

Best regards,

Volker

It's a bad LED. Silicon carbide based LEDs (specifically blue and white which are blue with a yellow phospher) occasionally have intermittent pad bonds inside the package. What you may be experiencing is metalization migration at the bond. Did you ever get a replacement LED? I forget where this ended up.

i got the amp repaired after the first blackout.
Repaired by Fender Germany, Düsseldorf. No Problems for 2 Month.
They did not write what they did..
Maybe another LED (I Think Three are in there)
Maybe they changed only one..
