Last week it couldn't be used, no electrical output, the lamp indicator was die.
Before I decided to buy the new one. I tried to open the cover, and check what is the cause of the problem.
Finally I noted, the problem was caused by a cracked tin. It may happen for hot circuit or high current/voltage.
I took the soldering iron and the tin to repair it.
Now it is back to normal.
Bellow are the steps what I did :
• Unplug/disconnect the electric input
• Remove the screws using screw driver
|2 screws must be taken out using screw driver|
• See the picture, red arrow show the cracked tin on the pin of the Power IC
At 50x Zoom you will see :

• I did to solder it
• Take the cover back and fix the screws.
If you have the same problem may be have the same cause, and the same solution.
