Just some advice which may help. If the diode is a large one ie a black diode about 5mm long (if it is still there) Then it probably is a rectifier and I would try something like a BY127 or a fast recovery diode of at least 400v working. If it is a small glass diode it would be something like a 4142 signal diode of around 50v working. Look for something similar in the same area and if there is one then check the details of that to verify. If the circuit marking has a diode symbol with a small line towards the + point of the image then it is a zener which will need further investigation. You can try an internet search for a service manual for the TV which will cost, but in the end it will enable you to identify the component.
