Upgraded V2 to blue, remote won't work

[cableguy2]

Hi Guys!

Firstly let me say i'm totally new to all this cable stuff so apologies if i ask any stupid questions

My mate gave me a Euro Vox v2 (i think) its this box (pbinfo.co.uk/images/box.jpg), he gave me it because the remote wouldn't work, he said someone had told him to upgrade it to a blue box and get a new remote.

I got this remote (pbinfo.co.uk/images/remote.jpg) but it doesn't work, i've read on the forums that faulty sensors are quite common, where can i get a new front panel or new sensor?

If i can't fix it i could alternatively make a little ir controller but i still need to sort out the channels, half of the them don't work or are in the wrong place, is it the CDF file that maps the channels to frequencies?

Cheers Guys!

Update:

I've just made a null modem cable and used the cable tv junkie blue updater to upgrade the box, it said version 1 detected and it successfully upgraded the box to version 2, i also used the CDF from here: (techwatch.co.uk/forums/26410-newcastle-cdf-file.html) the box boots fine and the channels are all there in the "usual" order rather than the alphabetical order like before i upgraded.

The remote still doesn't work and it just says "Searching for signal" and none of the channels work neither does the EPG display anything

Any pointers would be fantastic

Another Update:

After a lot of searching i have found a CDF file for my town for Jan 08 and all the channels work perfectly!

Its just the remote i need to sort now

Does anyone know what the specs on the IR receiver are?

I have a TSOP1738 anyone know if that'd work? After looking at the front panel board it looks like the IR receiver has its own set of wires back to the main board so if replacing the front usually fixes the problem then its just the IR receiver that's knackered...

Thanks guys!

i had 1 on a max unit and i tried reflowing all the solder joints on the sensor board and it worked for me. worth a try remember and use flux first though or you'll end up with dry joints eveywhere.

Hi Guys..

gadgetfiend: Thanks for the tip, I tried redoing the few joints for the sensor, but it didn't fix it

In the end i broke out the multi meter and figured out how the sensor was wired, its a 5v 38 kHz receiver, i changed it for a TSOP1738 and its working great!

I have attached a quick how to for electronics noobs..

1. Remove the old receiver with a de-solder pump being careful not move the sensor around before all the contacts are de-soldered otherwise you'll pull the track away from the board.
2. Trim the foam a bit, the new sensor is thicker than the old one.
3. Cable tie or tape the sensor in place while you solder the receiver, don't try to move it after you've soldered it otherwise you'll pull the track away from the board .
4. When soldering the new receiver on be careful not to heat up the component legs for more than a second or two otherwise you could damage the receiver.
5. If you do break the track like I did on the last pin then just put a bit of wire from the jumper to the receiver leg and a bit of solder on the wire to ensure a good connection.

Hope that helps someone

Thanks!

not sure on this but don't you need a max remote when putting blue firmware on ev2?

[cableguy2]

Hi Pete,

Yes you do, i have both the original remote and a max remote neither worked before i replaced the sensor...

I just thought, if anyone is looking for a TSOP1738 you can get them at: mutr.co.uk/catalog/product_info.php?products_id=1094
