This is an update to my thread but as things have moved on I thought it better to post a new thread with a useful title to properly document the issue.
There are also similarities with this thread and this thread.
Summary
There's a problem using the timer (Menu>Settings>Preferences>Time>Power On Timer) to wake a 2000T. The 2000T will not properly wake up: there'll be no HDMI output, and recordings will not be accessible.
After much testing I now have a better understanding of what the problems are. Unfortunately I don't have a solution though I do have a somewhat convoluted workround.
Let's recap my situation. In one room I have an LG 32LB580V TV and a Humax HDR-2000T. These have worked together happily for about two years. For convenience and power-saving the 2000T is turned off at 01:00 and on at 09:00 using the timers (Menu>Settings>Preferences>Time>Power On/Off Timer). Lets call this equipment TVA and HumaxA.
In another room I have a recently purchased LG 42LF652V TV and a Humax HDR-2000T purchased new direct from Humax a couple of weeks ago. Lets call this equipment TVB and HumaxB. I configured HumaxB to the same timer settings as HumaxA but there are two problems when HumaxB wakes up:
1. TVB reports that there is no input signal from HumaxB (let's call this the "no output" problem)
2. the media button, video option, and live pause buttons on HumaxB remote do nothing (let's call this the "no media" problem)
(Problem 1 can be "resolved" by unplugging/plugging in the HDMI lead, which is how problem 2 becomes visible.)
After testing, I can add that:
- Simplink (LG's CEC) on or off make no difference
- using different HDMI ports on TVB makes no difference
- using different HDMI cables between TVB and HumaxB makes no difference
- all HDMI ports on TVB and the equipment normally connected to them work as expected, except HumaxB
- the "no output" problem only occurs if TVB is not on (i.e. showing a picture) at the time HumaxB wakes up
- HumaxB appears to work normally if woken manually rather than by timer
- although the "no media" problem suggests that the hard disk isn't available, in fact it works normally and scheduled recordings are made
- I also have a Foxsat HDR connected to TVB by HDMI with the same timers and this always wakes up properly
As I have two 2000Ts in different rooms then I temporarily swapped them over so that BoxA is connected to TVB and vice versa. In this configuration then one of the symptoms moves but the other stays where it is.
HumaxA -> TVB = no output but media etc is OK
HumaxB -> TVA = output OK but no media etc
Conclusions
Because both 2000Ts exhibit the "no output" problem only on TVB then there's an incompatibility between Humax's and LG's software in some circumstances.
Because HumaxB always exhibits the "no media" problem then it is faulty or, more likely, there's a software bug which only manifests itself in certain circumstances.
I think it unlikely that returning HumaxB for replacement would resolve either of these problems as they're most likely software-related and it's difficult for me to say whether the "no output" is Humax's or LG's problem. Both 2000Ts and both TVs are on the latest versions of the software according to Humax's and LG's websites.
Workrounds:
- don't use timer to wake
or, if using timers on HumaxB
- the "no output" problem can be worked around by waking TVB for a couple of minutes using its own timers either side of HumaxB waking
- the "no media" problem can be worked around by scheduling a short recording soon after after HumaxB has woken up.
Of course, all these workrounds come with disadvantages so it's a question of deciding which problems I'd like to live with.
I'll report all this to Humax purely for completeness though I don't expect any positive result. In the meantime if anyone has any other suggestions or is experiencing similar problems I'd love to hear about it.
