Greetings

I just bought a busted RS2 off of a fellow forum member, and I'm attempting to repair the damage to it. I've found the likely culprit -- a fried diode on the main processor board. The diode is labeled D1 on the PCB. The JVC part number for the board is NAL0053-001. If anyone has any inside information or can otherwise assist me in identifying the part number or specifications for this diode let me know.



Any help is much appreciated.

A diode with 3 terminals is no regular diode. Do you see any others nearby that are not cooked? Can you see any markings on it?

Looks like that diode has been replaced before. Might want to consult JVC to see if they can recommend a better substitute.

The closest one I can find (it looks about the same size as D1) is D4. All of the others are definitely different sizes.

There is a N and what looks to be a marking that looks like a Tetris piece on it.


Not sure how to identify the part number from that.

I looked through all these logos but so far could not find a match. If you can look for others and find the Mgfr, that might help.

Thanks for the help. That website is especially useful for the future, even if it did not yield results here. I called JVC and the tech tried to help me identify the part but in the end he doesn't have a part number for D1 because it not considered a replaceable part -- they usually replace the entire board. I ordered the whole board for now -- but my hope is when I get it to be able to identify the diode off of the replacement and get the original working so I can return the replacement. If I can't identify it, then I will keep the replacement board.
