    I turned on the radio after a week and changed the frequency. I noticed the frequency flashing, tried to key up, looked like it would TX but it would go back to stand by mode after 5".
    No matter what i did the frequency wouldn't stop flashing, even turned it on and off, nothing. So i decided to perform a master reset.
    After the reset, the display wouldn't light up (lights), and no audio.
    Haven't put up a power meter to check the output yet, so I don't know if it transmits.

    Any thoughts?

    Last one I heard of doing that had a couple of burnt resistors. Dont remember which ones. Is it the entire display or just the tx/rec indicator flashing? The resistors on the one I saw kept the tx rec indicator flashing. When it turn off and back on, the display would not light at all.

    So, Yesterday afternoon, I switched on the power supply and I thought of giving another try.
    I wasn't expecting anything.
    To my surprise the radio turned on like nothing ever happened! The only thing that everything was erased, caused I did a master reset.
    It receives and transmits, lights and everything work, like brand new!!
    I haven't turned it off since...

    I would recommend removing the front panel module, and use switch cleaner on a rag to clean the metal spring contacts that connect it to the main chassis - that's probably your problem. (so it's likely to happen again)

    I bought my FT2800 when it was only a year old, for just £30 on eBay, as it was faulty . . . that was all that was wrong with it!
