Mitsubishi HS-E82 VCR Bad Picture

Good morning everyone.
This time I have a Mitsubishi HS-E82.
It was a bargain that I found with original remote included.
The problem reported by the owner is that it was working but no output video.
I took it appart and immediately saw that three 470uf capacitors were leaking on the signal board and one in the Hi-Fi board the same value too. I have located them in the pictures in red marker.
I replaced them, cleaned all the liquid remains and the video output got working again.
I saw too that were three surface mounted capacitors, two near the 470uf and one in a vertical board. I replaced them too, they were leaking too.
I replaced one surface mounted capacitor in the drum motor pcb, it was leaking too.
Now, resuming.
I have video output, vcr menu and tv channels with good picture, if I attach RCA cables to audio input AUX, and a bluetooth receiver I have good Stereo Sound, but no stereo in tv channels nor tape playback. I have the problem you can see in the video that I´ve attached.
I cleaned the upper drum heads, with printer paper and IPA, like I do to my other VCR´s, no luck.
Is this bad worn heads symptoms? Or I need to investigate deeper in the pcb´s for more bad caps?

Thank You!

Hugo.
