Is working in the field of manufacturing television sets permissible (halal) or forbidden (haram)?

If your work is not connected to the manufacturing of devices that are often used in sinful acts, and it does not assist in them, then there is no issue with your work. However, it is more preferable to leave it and search for another job that suits you. But if you are directly involved in manufacturing these devices yourself, or you cooperate with those who manufacture them, and since it is common today for this device to be used in sinful acts, then it is not permissible for you to work in this field.
