Repair Dolce Gusto Circolo Leaking Problem

My Dolce Gusto coffee machine started leaking without even plugin in to the socket. Water was leaking at the base, the tank would get completely empty in a few seconds, so I dismounted the back cover to see.
Use a Torx tool.
 Fisrt start removing the two screws down besides the reservoir connector.
Down there you see the join inside the water connector. That small rubber joint was apparently in a good shape but the problem really came from it.

I took the small water filter and descaled it by diping it in white vinegar for a few minutes.
Then I took a rubber tap joint from my tool box and put it on top of the rubber joint as you see it in the circle. Then I mounted all back again and it works! The joint was just too used, and you can replace it with a tap rubber joint, just find the right size.

Descale the coffe machine

This is always a good thing to do every two or three months to keep the inside clean.
I descaled completely by filling the water tank with a mixture of water and 10% of white vinegar, I inserted the empty capsule holder and pressed the lever as if I were making coffee till the tank was empty.
Then I filled the tank again with fresh clean water and repeated the process to rinse.

And here it is! Making coffee again!

Repair TV LG Plasma Screen no Power

This is a fix for the LG TV Plasma model 3500 and it will work for many other TV models. The screen tooks longer to turn on until it went completely off. I tried the hair drier trick that worked every now and then but it was getting worse anyway and it needed a fix.
When the TV screen does not turn on it is 90% because of a power supply board problem. It may be the capacitors, or not.
I took the cover off and there you can see the supply board on the left hooked to the main board.

When I examined closely the supply board the capacitors were all right, so I turned the board around and repaired all the bad welds, there were seven or eight that looked bad. I really had a hard time with my soldering iron as it took about 5 minutes to heat every spot, I think it may be a faulty one but it did the job anyway and we can enjoy our TV back.
This TV costed about 500 euros 4 years ago and to repair it today it has only costd me a few drops of soldering tin. And patience :) I am glad it works know and I wonder how many things people throw away because they don't know it can be repaired easily.

You can see all the details in my video:
