Error in meta_query not get result

I have this WP_Query

<?php
        $args = array(
        'post_type' => 'banner',
        'posts_per_page' => 25 ,
        'meta_query' => array( 'relation' => 'AND',
        array('key' => 'ads_status','value' => '1'),
        array('key' => 'adsposition','value' => 'top'))
        );
        $slide = new WP_Query( $args );
    if ( $slide->have_posts() ) : while ( $slide->have_posts() ) : $slide->the_post();  
    $yourfile = get_post_meta(get_the_ID(), 'yourfile', true);  
    $adsposition = get_post_meta( get_the_ID(),'adsposition', true ); ?>
     <img src="<?php echo $yourfile; ?>" width="1350" height="515">
    <?php
endwhile; endif;
    wp_reset_query();
?>

I have tow meta box (ads_status,adsposition) and its saved good in wp-admin, but in home page not show any result, but when delete meta_query, Its work and get me result.
