Now very often my 3.5 screen goes white and Cobra stop working (Cobra OEM kit).
So I hooked it up to external power supply running 6.0 Volt, Cobra takes about 350-400mA, but after a while (sometimes just seconds) the screen goes white and Cobra load my powersupply with 1050 mA. The 5V pin in Cobra now only have 2.6 volt.
I look for hot components, IC1 on main-board is hot and also C2 on display-board is to hot.
I also tried to power Cobra (5V in/out pin) with 5.0V, after a short time, screen goes white and Cobra load 1450mA from my power supply.
I can’t see any pattern, sometimes this happens after a few seconds, sometimes after 30 minutes.
Nothing is connected to Cobra.
Did I get a “Friday car”, I can’t develop like this, and absolutely not ask my customer to try it…
-update-
I tested to erase Cobra with MFDepoly (Cobra say waiting for debug…). But after 5-6 minutes the screen goes white and Cobra consumes 1100mA, the “C2” component on displayboard is now very hot.
I kill the power and whait for “C2” to cool down. Power on again and Cobra runs for 30 seconds before it goes white again (consumes more power and “C2” gets hot again).
This is very unusual. Do you have another cobra? Can you contact GHI directly for RMA and exchange please. We will get back to you once we learn more about what is wrong with that one cobra.
…and GHI would not ship anything less than perfect. We will take care of you like we always do.
It sure looks like it the 3.5" screen. I had it running without 3.5" screen (just the 2x16 LCD) for 2 hours on 12V. I connect the 3.5" screen run Cobra on 6.0V, just 10 seconds and the screen goes white and hight power load again.
We have getting this same issue, using 4.3" screeen, we have tested 4 screens on different Cobras, but 2 screen pieces having this exactly same problem. Get hot, white screen…
I have had the same issue for some time. Also, I am trying to send an email to the support email address and it keeps getting kicked back with a 550 error - access denied - invalid HELO…arrrg
