Box Works But No Picture

[dfox]

Got a strange one here,

Family member with a MB Twin+, Working fine for months, box is unplugged for something else to be hooked up for a day or so and then plugged back into the same HDMI port with the same HDMI cable but on boot up the openvix splash screen displays and then nothing. Black screen, tried different HDMI ports and different cables, tv etc but nothing will show.

If I use openwebif everything is working normally, I can grab a screenshot, change channel but still nothing on the tv.

Any ideas? Is it the tv?

Thanks

Did your turn your box and Tv off before removing and inserting your HDMI cable. If not you could have damaged the HDMI port on the box/tv.

You can use the web interface to turn on debug logs (if not on) and then pull the debug log from the box and post it here in case it shows something useful

I had the same issue with an MB Twin (not the plus model). Worked fine for 6-9 months then occasionally would display the 720p splash screen, but not the 1080i OSD or channel video. I had to turn the TV to standby and switch off the power for a minute or so. Ditto on the MB Twin. Then power up both and it would work. I assumed it was some form of HDMI handshake issue. Eventually it got to the stage where I couldn't clear it at all and ended up using a different cable. Fingers crossed this has worked for some months now. I've been testing a new Mutant HD51 using the same TV for the past couple of weeks and I've had a couple of occasions where the 1080p image will not display. Putting the TV into standby for a couple of seconds seems to clear the issue, so maybe the problem is that the TV (8 years old Sony LCD) is not handling the resolution change properly.

Good advice about not hot-plugging the HDMI cable, though. You should ensure both devices are powered off (or in standby at least) before dis/connecting the HDMI cable.

If your constantly fitting and pulling the hdmi cable into the box you could have easily damaged it, especially if you can still see the video feed via the web interface. You should ideally use a hdmi splitter in these instances.

Thanks all, tried different tv, different leads and tried powering them on at the same time but still no luck. Its a family members box so will have to be sent back to me to test and the WOS

I still say they have very likely damaged the hdmi port if they have been constantly plugging in and removing the hdmi cable. A 10 quid switch would have prevented such a failure.

The issue is the family that probably don,t know (and don,t care) what they are doing..... I have a really good setup in my lounge which I simplify when we go away and my in-laws come ... but every time they manage to screw up the system because they are finger happy and end up powering off the systems to solve the issue ... but doesn,t always fix it......often its just that they have switched the remote to tv mode ...... but!

[dfox]

Im not sure what they have done but other devices work on the tv with the same hdmi cable and same input.

Maybe they have unplugged it and back in too much. Problem is they dont understand the implications. Well they do now ha ha.

I will wait for it to turn up on my doorstep and take a look.

Thanks

its a very common practice of unplugging and plugging in anything on electronics be it cables or usb sticks

Tested with and RCA connection to tv and it works so looks like the HDMI port is buggered.

HDMI ports are not designed for that kind of use, once the hdmi cable is inserted it almost always stays there and only gets removed maybe half a dozen times in its life. If you are going to be constantly plugging in and removing the cable it will eventually break especially for older or younger users who tend to wiggle the cable free instead of cleanly pulling or pushing it home.

All of my devices go through dedicated HDMI switches, this both protects the port on the receiver it self (I'd rather replace a £10 to £40 switch than a several hundred ££ receiver) and allows multiple devices to be attached to limited inputs. I do the same thing for my network too via a 16 port network switch.

highly doubt that kind of user abuse (forgive the term but that's how most manufacturers will view it) would be covered under a general warranty. Although I still recommend you contact the seller if it's within its warranty period just to make sure.

You could also remove the lid and see if the port it self is loose from the main board and if so you may just need to resolver it in place or get some one to do it for you. (That will definitely void the warranty however so use it as a last resort).

Before i contact WOS i will lift the lid off and have a look and see if it is still attached to the main board. I just cant understand how it shows the black openvix screen but then goes black, could it not be a handshake problem as mentioned earlier?
