Mostly the capacitors near the heat sinks will dry out quicker than the other capacitors….By the way, is it possible to perhaps measure some voltages to make sure the PSU is indeed defective?
If so, where should I measure them and what values are expected?

As already mentioned here, you should replace all electrolytic capacitors in the mear of the heat sink with the other one.
One was obviously defective.
Measuring the electrolytic capacitors when installed is not very helpful.
The elcos are not expensive, usually the shipping costs are significantly more expensive.
Observe polarity.

Here is the update.
I replaced all capacitors within the green rectangle marked in the picture attached (right-hand side).
Perhaps more should be replaced?
I have also measured output voltages and they look like this. Most are zeroes. Only 2 are correct.
1 - 5V (0V)
2 - 5V (0V)
3 - GND
4 - 3,3V (0V)
5 - 3,3V (0V)
6 - GND
7 - 12V (13V)
8 - 23V (0V)
9 - GND
10 - 32V (1,3V)
11 - 6V (0V)
12 - 3,3V (3,2V)
13 - 3,3V (0V)

Yes, replace them all. I had a box with the C7 broken, and that blow the half electroncs from the PSU.

How did you measure the voltage values, with the connector connected to the mainboard?

Since there is 13v on a pin, the IC is not exploded. Best is to change all caps , as told before. If still not working, then there will a voltage regulator on the main board broken. Is it worth do fix it?

No. The connectors were not connected to the mainboard during the measurement.

Voltage regulator is probably OB2354AP. If this is it, then it costs just 1 EUR. Worth a try if the replacement of all capacitors does not help.

The small electrolytic capacitors on the large heat sink should be changed in any case.
In my case, the heatsinks near the small electrolytic capacitors were defective

Thanks. I will replace all the 4 small capacitors as well as the biggest one I forgot about.
I also measured voltages with the connectors connected to the mainboard.
1 - 0
2 - 0
3 - GND
2 - 0
3 - GND
4 - 0,27V
5 - 0,27V

8 - 0
9 - GND
10 - 0
11 - 0
9 - GND
10 - 0
11 - 0

Update:
I have replaced all capacitors on the PSU but it did not help.
Shall I go for some other parts on the PSU? S8uch as suggested in this video: (185) Xtrend ET9000, ET9200 & ET 9500 mainboard & power supply repair - YouTube

I think the PSU is ok. If the IC is broken there will be no 12V. It can be also a stepdown converter on the mainboard. You have to connect the PSU to the mainboard and check the voltages.

You mean check the voltages on the mainboard?
But why are most voltages missing on the PSU?
By the way, can anyone with a working ET check the voltages coming out of the PSU? I would then compare the values with mine.
That would perhaps help me eliminate some possible causes.

The video I posted a link to suggests several repair options if one fails.
See the JPG attached.
It seems even two voltage regulators on the mainboard are indicated as possible culprits in this video: U5 LSP5503 and U4 2.5V.
In addition to the capacitors on the PSU there are also some other items on the PSU that may require replacement: F1, D6, R12, IC2.
Shall I go on replacing parts?
The best now would be for someone to please check the voltages on their working Xtrend /Clarke-Tech so that I can compare their voltages with mine.

No-one, please? 
Could it be an effect of dead battery? Probably not. Becasue as far as I can remember I have the latest bootloader.

The Sec board, including the battery, plays no role in newly built images.

Yes, I realize that. I'm just not 100% sure if I have it on my box.
Anyway, I would need someone with ET9000/9200/9500 who can check the voltages the way I did above so that it is easier for me to eliminate possible causes.
As I said, I have already replaced all electrolytic capacitors on the PSU but it did not help.

Difficult to judge this from a distance based on any 'voltages' measured when installed.
I have the et9200 here and have repaired it regarding the ELKO.
It's not the only one I was allowed and able to repair.
The box does everything that an e2 receiver should do in my opinion.
A flash after repair via USB was always necessary and interestingly, no Sec board has been defective so far.
Installing the old driver was always possible after the electrolytic capacitors had been successfully repaired and was therefore appropriate due to better media framework handling.
Are you sure the USB flash is actually being carried out?
Are you sure it's a working USB stick?
Preferably old and small or, as an experiment, just formatted in FAT?
