Generic problem for all Monitors
LG 500G MONITOR
IN MY MONITOR HORIZONTAL OUTPUT TRANSISTOR(C5855) FOUND SHORT. I REPLACED IT BUT AFTER FEW MINUITS IT BECAME SHORT.AFTER CHECKING I FOUND A DIOD(MUR460L)SHORT.I WANT TO KNOW THE FUNTION OF THE DIOD AND THE EQUIVALENT DIOD FOR REPLACE (BECAUSE MUR460L IS NOT AVAILABLE IN OUR LOCAL MARKET).

as your h/output got defective due to short circuit.proceed as follows.
isolate h/output section fom power supply& check power supply output is ok as you know high output may give such problem.
when it becomes ok, check hor.section
1 h/output
2 cap & diode connected in eht winding.
3 ptint short near eht.
4 at last eht tranf.
5 if it is ok re connect h/output supply.
put on set.

1 Function of diode is to convert AC TO DC
2 you can use BF159 or BF157 as equivalent.
