help with a supposed TV diode

good, I have a tv-monitor brand hyundai model hlcd-2200 the same I left to turn on, connect the cable to the network and turn on a led on the source I measure the output voltage and it is correct 12v https://ibb.co/mj3euk but when connecting the source to the TV and giving the power button the monitor does not turn on and the LED on the source starts flashing. The LED below the screen does not turn on. is then when I proceed to check the plate of the same and I notice that everything is good to the naked eye but I find a component that give me continuity as if it were short https://ibb.co/kWwcfQ prosedo to desolder it and see if it continues giving continuity because I think it is a diode and if it turns out that if there is continuity, then it would be a question of replacing and testing but here comes the question, the "diode" does not have numeration so I would not know for which replace it and in the union of the metal and the black part of the "diode" there is as a plastic union that is not own or that I have not seen in the diodes. Anyone know what component it is? and is it normal for continuity? https://ibb.co/bOWUAQ please copy and paste the links that I did not find how to modify them

Hello, the photos are not seen, preferably upload the photos with the image manager of the forum. From what you say about that component, I think it's a coil. Upload the photo and see how to follow.

pd: if of being a coil is normal than of continuity. I hope the photos

Samuel can see the image only by selecting the url until Q. Apparently as I told you it is a fuse or coil. Look for the fault on the other hand.

Samuel, I do not know if you managed to see the photo I attached in the comments, but the component says F81 so it would be a fuse (or if I do not distinguish the 8 from a B could be FB and I think that's how they put them to the reels? )

Friction thanks for answering the two components that are below the indicated also give continuity if they were a diode they would be bad for what you say I think that is not the case

Check the welds.

are distinct points, that is, each component goes on a different track. the other components look good

those last trea components that are seen in the photo are shocks of ferrite.no are diodes or anything that will be pare.sonos only wire inside a nucleus of ferrite, that is why they mark continuidad.saludos

I sent you this diagram of a similar model monitor, check it out, maybe it will help you. As for the diode, it looks more like a coil Hyundai_H-LCDVD2200MTK_sch
