I had a problem with the remote not responding but the program changes were available using the buttons on the Humax box. I have found the answer on here by restting the remote by holding down the TV and red buttons for thirty seconds, it worked, all is now well.
Thank you to the forum.

I Just bought Humax HB1100s worked on set up then the remote function froze. Took it back to the shop got a replacement which worked until the next day when everything froze again. The problem seems to be the remote rather than software. Looked online and found removing the remote batteries and holding down the on off button for 30 seconds can work. Did the trick for me, I would recommend trying this.

Several times since the last software update this has happened. I turn on and press the guide. Sometimes there is no info. and I get the rotating "I'm thinking" icon. This just sits there. If I am lucky I can come out of the guide. Whether I can, or not, I then find that none of the buttons get a response
I can't call up recordings, or the guide. I can't even turn over the channels. I have tried a full switch off & on again. After reloading everything it is still stuck on the one channel.
If I then leave it, after about 15/20 minutes it suddenly works normally. Any ideas?

Hi , I joined this forum to explain a couple of problems I experienced with the Humax box which I've only had a couple of weeks

Which Humax box do you have? If the remote has an STB button then I think you will have posted in the wrong section of the Forum.

Hi , I joined this forum to explain a couple of problems I experienced with the Humax box which I've only had a couple of weeks.First,after turning the sound down to take a phone call it wouldn't turn up again. I rebooted etc and finally moved the sound up manually on the TV before the sound on the handset was then able to kick in again.Second, and this is what drew me to this forum, my TV got stuck on one channel. I don't know how this happened. Anyway I fiddled but got nowhere. Eventually a relative happened to be round;with the TV switched on and with the stuck channel on he pointed the handset at the Humax box. He then pressed the STB button on the handset at the Humax box and control of all functions was retrieved. Really hope this info helps someone out there.

In the vast majority of cases it is not the remote control at fault. If the machine in question is a 9200 the problem is it's inability to process the remote commands quickly enough with all the other processing the machine has to do. Basically it is an old computer trying to run today's software.

I've had all sorts of issues with the remote control. Tried just about every suggestion I could find on the Internet including a new remote. I don't know what possessed me but for some reason I did a factory reset of the TV (LG) and the remote now works better than ever before. I'm sure there's a logical reason for this but I don't know what it is. Might be worth trying before looking for more complicated solutions.

It has no doubt been said before, but the 9200T repsponsiveness problem is caused by the processor being overloaded when populating the EPG

Is it the processor or a shortage of RAM?

On my 9200T the "remote control unresponsive" problem is much worse after the broadcaster adds a new channel, or shuffles the existing channels around. Once I have retuned the 9200T, the remote is much more responsive.

Also there are fewer gaps in the EPG if you reduce the number of multiplexes you are receiving. Do you really want Dave and others on that multiplex? I also delete all the radio stations as well on the ground that their EPGs will need populating. I am not sure whether reducing the number of multiplexes also makes the remote control more responsive but it probably does.

It has no doubt been said before, but the 9200T repsponsiveness problem is caused by the processor being overloaded when populating the EPG so anything which you can do to get the EPG populated (eg automatically switch on the 9200T 15 mins before you want to use it?) will reduce the times the 9200T is repopulating it, and so will reduce the times during which the remote control is unresponsive.

I have a 3900 unit and recently (tonight) the STB button on the remote is constantly red. This means I cannot use it, the unit itself does work ok. Any help please or ideas on getting a replacement remote? Cheers.
