I had the same problem which I lost few days on that.

Here my answer may help others, which helped to render pdf.

For me even though if i mention as responseType : 'arraybuffer', it was unable to take it.

For that you need to mention as responseType : 'arraybuffer' as 'json'.(Reference)

Working code

service.ts

downloadPDF(): any {
return this._httpClient.get(url, { responseType: 'blob' as 'json' })
        .map(res => {
        return new Blob([res], { type: 'application/pdf', });
    });

}

component.ts

this.myService.downloadPDF().subscribe(
    (res) => {
    var fileURL = URL.createObjectURL(res);
    window.open(fileURL);
    }
);
