Question about Jwin Televison & Video
I took a look at your user manual & searched for firmware updates for you, but was unable to find any reference to firmware upgrades for this unit. Therefore, there are only four reasons your player is refusing discs:
The discs from a different region than your player has been activated for.
The discs are scratched or dirty.
There is condensation inside the player.
The lasers lens is dirty.
If condensation is your problem, then no discs should play. If some discs play while others don't, you can rule that out. Place the unit by a moderately warm air vent to blow the water vapor out if this is the source of your symptoms.
If you want to try cleaning the lens, 'cleaning disc kits' are available. Or you can open the unit and very gently roll Q-Tips dipped in 99% isopropanol alcohol across the laser's lens until they come away clean.
I hope that helps.
