Hi friends
welcome back.After a long time again i am writing this artical revealing how i solved this Wipro monitor no disiplay complent.Before start pls look in to the photo snaps one came to my service center for repair.
Above is the one came for repair
Back view after removing back cover
Let us know what is happened to this machine.When i opened the chassie as useal i observed the filter caps bulged as a common case .see below for your reference.
After looking this really i felt very happy so that i can easily solve this problem.Confidently i replaced this filters and switched on the equipment to know the results.There is no any sign of light inside the monitor panel.Now i need to know & go for further investigations .
Further i glanced the circuit for any physical damage /crack on components/etc
Now my next step is to go for voltage test methods to catch the culpirt.Since the problem related to back light my doubt is to check the voltages in inverter pcb.
While testing with my multimeter test prob taken me to the fuse input which is showing open.This is blocking the DC12 Volts reaching further circuits inverter pcb.
After replacing fuse again getting open further investigated the reason to cause this. The main culprit is one of the inverter transformer.Replaced the inverter transformer which is removed from the junk board for same type, Now Monitor started working in very good condition.Happy to see this from customer end.This is the repair success story of wipro monitor.
Assembling the unit after repair
Happy to see the result after caps/fuse/inv transformer replacement
Thanking you let us meet in the next session with one more intersting sucess stories
take care with best regards.
