    Hello

    I have a Yamaha digital tuner model T-520, the signal goes out and I ear noise for few second and then the signal come back, every few minutes.

    I did check all the solders on the board and I did not see any broken solder joins.

    Any ideas of the reasons of that problem ?

    Thank

    Bye

    Could be a lot of things. Loose or intermittent antenna connector. Or an intermittent component causing the PLL to loose tuning and then returning. One thing you can visually check are all the larger electrolytic capacitors, looking for signs of bulging or leaking.
