Hello Technomaters!
Just wanted to test the new patch but my receiver is not recognizing any USB device.
Tried both USB ports but when trying to choose a USB drive from the menu a message appears: USB drive is not attached, it in fact it is!
Any idea what's wrong? Tried to switch the power off for a while, took several different USB sticks but nothing has helped.
What else can I do??
Thanks!!
My actual firmware is 7.44
It works again!Originally Posted by DJ2004
After doing 5 times a factory reset the USB ports work again, really strange....
There is a known problem with the usb ports failing with the tm6000 range. I think some capacitors on the mb blow after a while. My usb has failed and I haven'y got around to fixing it yet.Maybe yours is in the process of breaking but not quite got there yet!
here is a previous post with more details of the problem - and solution: https://www.satpimps.co.uk/showthrea...TM6900HD-Super
@DJ2004:-
Yes, it was me who had the problem last year and, so far at least, replacing the swollen caps seems to have sorted it out!
I also had found that doing what you did tempoarily sorted it out, bur only changing the caps actually mended it!
Please see Joany's link and think you'll find your answer!
I'd had to resort to adding patches via cable instaed of USB - as they had BOTH stopped being recognised, including obviously my PVR one!
Let us know how you get on mate!:respect-050:
Thanks a lot Mate!!
Well today the USB ports don't work again!
I think replacing the caps is what I have to do. I think I'll open the cover of my Tm and see if I find the right caps.
If it will be obvious which caps have to be replaced I'll try to do it at home, otherwise I'll bring the box to a specialist. Not sure if I recognise the right caps :-/
Let me know how you go on because i need to do the same myself, when I can be arsed to get around to it.
Hopefully I have Uploaded a picture of the 6900 Power Supply board.
I have indicated with red dots the most likely caps that give problems.
If you look carefully, you can see that the Top of the bottom Right Cap is slightly Bowed.
Replacing that capacitor, on this occasion, cured the problem.

Pretty sure they are the ones I replaced last year mate, although I seem to remember there were only three which had bulged, two of one and another - all of which were specified in the link kindly already supplied by Joany:-

Good luck guys, as matter of interest my symptoms seemed to be identical to those experienced by DJ2004!:respect-067:
@holmroad - yes -that was the thread where we were both subscribers
The temp rating of the marked caps Would have been OK, If the designers hadn't stuck
two big Heat Sinks close to them ! Any one changing them should make certain replacements
are 105 C not the original 75 C

In my case the marked caps have to be replaced, I simply ordered some caps with the same specifications like shown on the original caps.
When finished IŽll come back and report if everything went well...
Good luck mate!:respect-057:

M8s, I urgently need Your help!!
I just replaced the caps but my receiver doesnŽt work, it goes on and off again, the new caps get extremly hot and damaged after several seconds, whatŽs wrong??
IŽm not sure but it have to be wrong caps but I installed them properly, IŽm sure.
The upper cap on the image is the new one, the lower one is the original one.
On the back of the original cap is: 8063(M), the new one: 108C2(M)
Are these symbols that important and the reason for my problems???
Thanks and hope You can help me :( :( :(
Did you make sure the leg that has the large stripe down the side was fitted correctly, the legs are +ve and -ve and must be fitted the same way.
You also dont have much room in which to work - thats why I got my friend, who's far more adept at this kind of thing, to solder in the replacements as I'm sure I would possibly have touched one against another - and thats all it needs to constantly be shorting out or not behaving 'smoothly' as it should!:respect-069:
(Please also note the comments re TM having recommended different higher rated caps/resistors etc to avoid future prods!

As previously stated - make absolutely certain that you have the polarity correct, and take care when soldering, that no shorting solder blobs are left. Also, I notice that you are replacing a 220mfd Cap ?, when the previous major cap problems have been with the two 1500mfd, and one 2,200mfd caps, all at 10v working. There was also a recommended mod to increase the 2,200mfd to 3,300mfd 105 C working to improve smoothing and reliability
Had exactly the same problem the other week. Two electrolytic capacitors had bulged on the PSU board, got 2 replacements for pennies off the well known ******* site, problem solved!
Thanks for Your answers, polarity is ok, I decided to bring the power supply board to a local technician, I'm sure a technician can fix it without any problems. I'll report how it's going on...
Ok, everything works well again and "IŽm back in business" :-)
I brought the power supply board to a technician, he has changed 2 of the mentioned capacitors (shown on the left on the picture above) to 220”F but 35V, not 16V!! Originally there were two 220”F 16V caps installed, but for some reason the voltage is too high so he changed the caps for 35V, now everything works again, also the USB ports!
Cheers for all support!
Thanks for your report. Glad its working again.
@DJ2004:-
Same here, really pleased you got to bottom of it - also seems this must be a weakness on TM6900HD Supers, hence TM's advice on changing cap/resistorspecs etc!:respect-069:
