How To Repair No Power Fault In DVD Player
This DVD player was brought to me with the complaint that it became dead while playing and the customer, being an electrician with half cooked knowledge of electronics, opened the player and having found the fuse blown, bypassed it with a thick wire!
When he switched it on, he heard one explosion and in panic he brought it to me for troubleshooting. When I opened it, I saw what you all can see below:
The IC had blown to pieces because of which there was no way of knowing its number.
Having known the customer’s tendency to do self-service, in a crude way, I dismantled the whole DVD and noticed that this over-smart guy had put a rubber band in place of belt on the loading motor!
Connected boards and tried it out.
It worked very well. So, fit it back.
Here is the picture of defective power supply board, the rubber band, which I replaced with a belt and a cut belt found inside the DVD player.
Thus accomplished in adding another one to my satisfaction list.
