Coby DVD Player Repaired
Customer complains that when he plugs the player into the outlet an explosion occurred and some smoke came out of the player.
First thing I did was to open the player up and check for any sign of burnt component… I did not want to apply power because the complaint was smoke and explosion inside the player.
After that I notice a Capacitor shell with the markings of 10uf 16v (See picture) fell out of the player.
I look for where the Cap came from and I replaced it.
I did not stop there I continue checking the other surrounding components and found all to be good.
In the picture above you will notice that the fuse is not a glass fuse but a piece of wire on the Circuit board. I unsoldered the wire and did the light bulb trick. The light bulb did not light, and the power came back On but there was no sound coming out from the speakers. I use some other speakers for comparison and the problem was still there. I began to trace the exploded cap and it leads me to a power amplifier IC TA8227P.
I suspected that this IC has been damage as well and I directly replace the IC and tried the radio again and there was sound from the speakers. Problem solved.
