As they age, these boxes are showing various fault symptoms - provided you can work safely & solder correctly, these are easily fixable.
On the power supply board, there are 3 electrolytic notorious "Capxon" capacitors that fail with time. Bit surprised Humax used these rubbish caps!
C21 1000uf 25v
C12 & 14, both 2200uf 16v or 25v
These are cheaply obtainable from Ebay, normally the 105deg temp rating type will be supplied. Try to keep the one nearest the heat-sink, as far away from it as possible.
The PSU, which is probably used in other Humax boxes is type: PW718s
The large smoothing electrolytic & smaller ones rarely fail - it seems low voltage 680uf - 2200uf Capxon ones fail in many pieces of equipment.
Once the caps are replaced, problems like
A. reluctance to change channels
B. slow population of EPG
C. smearing of movement within recordings, all vanish.
Very probably caused by reduced voltage or hash as the Capacitors age.
Other than the fact these boxes are not HD, they are quite good performers. Though why they hid some of the remote functions under a cover, beats me!
The 9150 usually needs a factory reset to wipe the old channel storage away & other errors, following Caps replacement. strangely the 9300 works with just a rescan!
