    Beware of tunnels in Greece

    Their egos may be - but otherwise they're lower than a snakes belly.

    Encrypted RF Signal?

    Range? Frequency? Security level? There are many dedicated encoder/decoder pairs that are designed for use with such systems. https://pdf1.alldatasheet.com/datasheet-pdf/view/477249/RFSOLUTIONS/RF600E.html is but one example. You need to be more specific.

    Switching a RF signal

    OP states that it is a signal from an aerial ..where either very low levels (receive) are concerned or higher levels (transmit) are to be dealt with. In either circumstance the best i.e. lowest loss device will be a relay.

    Should I check everything?

    They sound as if they are the main PSU smoothing capacitors??? If you can disable the DC output to the main circuit and test the DC voltage with new capacitors fitted - just to make sure everything is tikkety-bo - then do so. You could also fit low ohms resistors (or simple incandescent bulbs)...

    Hello, can somebody help wich transistor is like bfg520

    When someone wants to learn something they don't start with something beyond their capabilities/knowledge. i.e. a mechanic doesn't become a mechanic by designing a car..... similarly someone wanting to become fluent in electronics doesn't start by designing a hadron collider..... You need to...

    What about the KISS principle and a simple RF coaxial relay?

    Crt tv power problem

    How many pins on the plug? If it has three pins then one pin WILL be longer than the others - it is the earth pin.

    Hello, can somebody help wich transistor is like bfg520

    @Audioguru is doing an excellent job TRYING to give you the assistance you need but his efforts are being thwarted by your basic lack of knowledge or understanding of the basic principles and your repeated errors in making the simulation properly. You do not show even a simple understanding of...

    Missing remote and motor controller

    Has there been any damage caused by the water? I see something above IC6 and a 'link?' close to IC13. Either way, if the board is activated by an RF key fob then the signal is probably coded to the board and finding out what code is required won't be easy - may be impossible.

    I have an RCA LED55C55R120Q 55" LED LCD tv. The screen went black. See details.

    Usually caused by 'one or more' LEDs in the backlighting strip(s) having failed. They can be easy or difficult to change. Obtaining a new 'strip' (as they are mounted behind the display in strips, keyed left or right) is quite easy but some models require that you physically remove the LCD...

    Self drive car

    Given that car manufacturers spend BILLIONS on such projects and you figure you can do it with a $50 Raspi I reckon the car manufacturers would like to talk to you! They're definitely missing something!

    Get a copy of Yellow Pages (or Google) and look up "chauffeur" ..... then show the chauffeur how to use the Raspi.

    Xbox One S Controller Repair

    The key soldering area is the 'grey bit' to the left of the * - this is where a part of the PCB track has come away. If the track isn't part of the bit you pulled off you will need to solder a connecting wire across the gap from the end of the connector to the little capacitor close to it.

    PlayStation2 clock is dead, but battery is still good

    Easier to fit a new battery and see if it cures the problem

    Xbox One S Controller Repair

    Looks like it could be soldered back in place - with some careful work...... Do you have a suitable soldering iron? And fine solder? Not a job for the inexperienced I'm afraid.
