MCP turns off or showing errors

Hi everyone, this is my first post on this forum. Nice to meet all of You!

I am user of OC MCP for almost one year. Everything was fine, but for just two weeks I am having strange problem: MCP turns off during the flight. I have to reload script or just switch somethning by mouse manually - then sometimes it comes back fo a while. But sometimes I see something like that:

http://www.cat.przestrzen.pl/CSB/upl...ok_pg2008s.jpg

It no matters if it is conected and powered by motherboard, powered-hub or powered itself directly from adaptor, SIOC 3.41 or 3.5 either.

Please help!

Thx.

Hi,

Which aircraft are you controlling with this MCP? and with what SIOC script?

Nico

I use only freeware models, for example IFDG A320, MD11 and so on. Sometimes everything is ok for 20hrs of flight, sometimes it is not possible to fly at all. Here is my script (little moded for my cockpit):

Hi Slupek,

Unless you've changed something in the SIOC script recently I doubt that's the problem. If it's worked well for the past year and only now failing I would suspect a hardware problem within the MCP or perhaps a newly installed piece of software. Unfortunately intermittent hardware is more difficult to investigate than hardware that won't turn on at all.

Take out the MCP and visually inspect all soldering points and check for dry joints (i.e. soldered points that have come loose). Also check for burnt out resistors or poorly connected components. It could also be a failing IC. These are usually reasonably cheap and can be replaced however you need to establish which, if any, is faulty. You should be able to get a circuit diagram from OC which will help, however reading this depends upon your electronics skills.

It could also be linked to some other software running intermittently while flying. Shutdown all other services like Anti-virus software and see if anything changes.

It's tricky but you're going to have to do some careful investigating to track down your problem.

Good luck,

Ken.

Thank You for answer Ken. So, I will make an investigation then, as you advise. First I'll try by software-side and will install SIOC and MCP on wife's notebook, then I'll see.

I'll let You know.

Regards.

Adrian

Adrian,

Have you also tried the MCP Test Program from OC? This might help track down any issues.

Ken.

Not yet, but I'll try. Thx.

Mine would shut off every once in a while. I noticed a broken solder connection where the USB cable connected to the MCP's board. I guess as the MIP got warmer things would expand and break the connection.

My MCP is doing the same thing . I have disabled all AV stuff etc and it seems like after roughly 1 hour the MCP switches off. I have to then reload the script and all is OK for another hour.
I am using the script by Nico Kaan for the LDS 767 and also the script for the 737 and the same happens with both.
I checked the USB settings in device manager as I thought maybe the power was being shut off to the hub, but that was not the case. The unit is only a couple months old, but my next check will be to open up the case and check the wiring etc.

EDIT..Latest...I have checked all connections etc. Nothing awry there. So this is ongoing problem.
