Electronics Question
 

I have an inexpensive bluray player that has become totally non-functional after a thunderstorm. It is powered by a plug-in 12 volt, 1 amp transformer which is not damaged and is still functional. I could understand if the transformer were damaged, but I don't understand how the bluray player was destroyed. Any thoughts before I throw it away?

I can take a look at it, but here is a possibility, if it was connected to a TV with cable, you may have actually had a surge that ended up going through the blue ray player. I would be glad to discuss with you if you like, send a PM.

Thanks VT, but it is really not worth the effort for a 60 dollar unit. It was a friend's player, and the player was connect to a TV via an HDMI cable. It just seems strange that a bluray player with only an HDMI and a low voltage power cable connected would stop working with no other apparent damage.

It's the capacitors in the power supply. Look for split/bulging caps. It's downstream from the transformer

The power connection is the yellow box in the lower left corner. The external transformer works fine with other devices. I think it would be too difficult to remove the circuit board because I would need to disconnect a lot of plug ins.

Well, if you're not going to remove the board there is no point looking at the schematic.

Typically, it's a power supply issue. The Chinese tend to under spec the caps.

It looks like you will have to let a few moths free by opening your wallet and buy a new one

Thanks for your input.

Just checking in the event that the Blue Ray Disk was put in upside down? Or does that baby not turn on at all?

Remember, the flow is connected to the Dynaflo. What does that Mean? I don't know. "THE HONEYMOONERS": Norton the Engineer - YouTube

Not being a wise guy :boxing2: just thinking outta the box. I've seen it all! :ohdear:

There is no disc in the player. The player will not power on at all.

OP, lightning is a strange phenomenon, and problems like you are describing can happen when there is a remote ground (think cable or satellite cable) connected to the equipment, in this case, the connection was probably through the TV set, which apparently survived. I am guessing, there was a surge, it was capacitively coupled through the power supply or the cable to an internal component that was tied to both and failed.

You may be correct. The Comcast cable box was damaged, and one of the HDMI TV inputs was also damaged, but not the one connected to the bluray player. The bluray player only had a low voltage power connection and an HDMI connection to the TV, neither of which was damaged.

I think you are one heck of a guy! I've seen your post offering help many times and am impressed.
