One day i heard a the HDD of my VU+ Duo2 clicking. Afer a power cycle there was only a flashing blinking white LED on the receiver.
After i opend the box i saw the swelled capacitors (C8/C9) on the power supply.
I removed one and make a short measurement and there was only 118.5µF left.
This are two 25V 1500µF capacitors.
You can buy this at several stores here is one from „reichelt elektronik“:
If you want to buy it somewhere else, look for a „low ESR“ version.
I removed the old ones and solder the new ones in and put the power supply back into the receiver.
After the replacement my box boots normaly.
