Vu Duo hangs during startup

[Arcy]

I'm trying to revive my old Vu+ Duo, which hasn't been used for a year or two, but unfortunately it fails to complete the startup process. It jt hangs with the splash-screen displayed and the spinner spinning.

I've tried reflashing the box with several different USB sticks and various images (most recently, the latest OpenVIX 5). It completes the installation as normal but then always gets stuck during startup. I don't think this can be the same as the red light problem -- I haven't seen that at all, and the capacitors look OK (for what that's worth).

Though the spinner is present, I can ftp into the box and can also log in via telnet. By issuing
init 4
enigma2
... I can watch what happens as enigma2 restarts. It breezes through the various loading and configuration commands for about 20-25 seconds until it gets to the [VideoHardware] section, but it gets no further than the fourth of those, which is
[VideoHardware] setting policy2: letterbox

Can anyone suggest what the problem is? I'm wondering whether it might be some obscure fault like a ram failure.

[timofee]

I would change the well known c807 capacitor anyway. The capacitor costs only about 50p and it's easy to solder.

After that you have to start looking at other capacitors and some regulators. The regulators are a much more difficult soldering job.

It's all explained in the long red light thread.

Thank you, timofee. I'll give it a go, though I'm doubtful that the power supply can be the problem, since ftp and telnet operations always seem to work normally, and the start-up sequence sticks at the same point every time.

[Arcy]

I've now replaced C807 with a new 105deg-rated one, but it has made no difference. There was no sign of swelling on this or any of the other electrolytics. I'm still doubtful that the fault can be in this area because the Duo gets a long way through its boot sequence and continues to be accessible via Telnet even though the startup sequence doesn't complete. I can also access the files on the internal HDD via ftp. Would any of this be possible if there was a power supply fault?

The startup sequence gets as far as the stage where the VIX spinner shrinks and jumps into the top left-hand corner (implying a screen mode change). The spinner then continues to spin indefinitely against the backdrop of the 'please wait' splash screen.

Does anyone know whether there is a way to enable debug logging from the command line?

Are there any crash logs generated?
Look in /home/root/logs/

maybe clear : is it a vu duo or vu duo2 ? VU2 duo does not excist.

[Arcy]

Thank you for the suggestion, judge, but alas there is nothing in the logs folder. However, I think there may be some obscure hardware problem. I've been prodding at this receiver occasionally for months. This afternoon, I removed the PC to replace C807, to no apparent effect. But this evening I switched the box on yet again, probably from force of habit, and when I looked a little later I saw to my amazement that it had booted into the startup wizard. And it let me go all through the setup as normal. But when I rebooted later, and on all subsequent attempts to restart it, it has simply hung with the spinner going, as before. So I must have just got lucky that one time.

For clarity -- this receiver is Vu+ Duo. The Vu2 in the subject heading was a typing error I failed to notice :-(

I have corrected the title.

There was a bootloader update a while back, maybe you can try flashing that first.

As to establish what the problem is, you can start enigma2 in console mode. This will tell you what the problem is. Link to Linux commands in my signature if you need it.

init 4 && enigma2

[Arcy]

Many thanks, abu b. I've now flashed the latest bootloader from the Openvix downloads site and also the latest 5.0.009 Openvix, but the box is still getting stuck in the same place. Unfortunately it hasn't yet repeated yesterday's feat of actually completing boot-up. The console log looks like this:
