These capacitors can be tricky to remove, so take your time. However, there is a good chance you will be able to resolve the short. Good luck!

I carefully removed the capacitor and cleaned it. After a bit of cleaning, I tested it with the multimeter and it measured open circuit. I checked it a few more times, to test, and it kept measuring open circuit. I also checked it with my capacitance meter, and it measured more or less 5pf to 340pf max. I installed it back in the radio. I turned the radio on, and all bands are now ok, with good reception. there is only a small problem on long wave, there are some pops and crackles across the band ( independent of frequency ) with internal and also external antenna. You can hear it a bit in the background when tuned into a station. I will try to trace that problem later. Any ideias / advice about this issue are welcome. Thanks everyone for the all the valuable help.

Excellent. Glad you have fixed it.

As for the noise, it may still be a spec of dust or something like that on the tuning capacitor. LW tends to be far more sensitive to such things due to the overall noise floor. The first thing I would do is wait for 24 hours to allow any cleaning fluid you used to fully evaporate. If the problem is then still the same, try a squirt of compressed air if you have a can available.

Hello Adrian. I waited for a day or so, but the noise is still there. Later, I will try to carfully clean the capacitor some more, hopefully solving the problem. I will post later with the results. Thanks again everyone for the all the help.

Try checking LW with another radio, the noise may be from an external source rather than something wrong in your Grundig.

Hello Paula. Thanks for the advice. I did that, and the other radio does not have this noise present. After I clean the capacitor, I will post results.
