I turned my amp on tonight and all I get is a blank silver screen.

Any ideas folks ??

Turn off try again. If that doesnt work unhook all keying cables and try it.

Unplug the amp, remove the keying cable and try again.?

That worked, thank you, but I'm wondering if I just bumped the power cable and only had 1 leg of the 220 making contact,
It is very tight confines there.?

Happens 2 or 3 times a month for me. All cables tight. Glad no pain in flipping the switch a few times.

May sound strange - but my experience is that if amp is turned on before the radio the WSOD (White screen of death) doesn’t happen! - please give that a try next time!

I wish palstar address this issue and may be provide a firmware update if it can be fixed by one.?

Maybe, but mine is usually the last in the string to be turned on and I've never had a problem.

And, in between QSOs, while just listening, I'll turn the amp off, then back on when I need it. ?

Makes no difference that I've ever noticed. ?I run it on 240v, by the way.

It appears to be the data cable. I have an FTdx101D and a 7610 both connected to the LA-1K through a cable switch. If I turn on the amp after the radios I will occasionally get the blank screen on the LA-1K. The cable switch has 4 positions so I have been selecting an empty position before I turn on the amp. I have not seen the blank screen on the LA-1K since.

I have the same issue with the blank gray screen at times. It is intermittent and not really a big deal but the first time it happened I thought the screen had died.

Anyway to fix the issue I turn off the amp, unplug the USB Band control cable from the Flex (this is the easiest cable to reach) and plug it back in. Then turn the amp back on. This works every time. I normally don't turn on the amp unless I need it.

Interesting thread!?
I've been using my LA-1K for over 4 years (often daily) and have NEVER experienced the blank display problem discussed here.

For what it's worth, I'm driving it with an IC-7610 with no band data cable - amp is totally auto sensing.
I wonder if using a high grade USB cable (with torrid chokes on each end) would help?
 

Very interesting my amp never does that no matter what series of on and off the radio or the amp or switching to my second amp
 

This is the first time I've read about this issue.? I have 2 LA-1K's and have not experienced this issue with either.? I use the band data cable to connect to my 101MP and SteppIR controller.? I sometimes turn the amp on first and sometimes turn the radio on first.

Same, my amp has never exhibited this behavior, but like Thomas, never used a data cable (la-1k is RF sensing so not required). However, I just assembled a data cable for the FTDX10, and will report back if I have this problem.

When I was using my LA-1K I never had a blank display. ?Art W1SWL
