Default Sony SCD-1 Firmware Upgrade Chip Version 2.53

Sony SCD-1 Firmware Upgrade Chip Version 2.53

If you own a Sony SCD-1 or a 777ES SACD Player and it has Firmware Version 2.40 and you experiance a loud burst of noise at the end of some tracks, YOU NEED THIS CHIP! This is the chip Sony released to fix that problem. Will upgrade any Sony SCD-1 or 777ES Cd player. I ordered this chip just before they were back ordered. it arrived after i sold the player. Now is your chance to buy one of these rare unobtanium chips!

$75.00 plus shipping:

$7.00 Fedex Ground Shipping within the US
$20.00 Global Express Shipping to Most countries.

Yeah, you are right, unbelievable but true Sony made such a blunder in a flagship model.
It should ALWAYS be replaced under warrenty!
But your chip is a big help for those who lost warrenty, highly recommended!. You don't need to solder it, it's in a socket.
The loud burst is after the last track at some CDs

Forgot to mention. to check what firmware level you have.

Press the "Text" Button on your CD Player and at the same time press the "Check" button on the remote. A long string of numbers will appear on the display. The first four are the firmware version 0240 = V2.40, 0253 = V2.53 etc. To get out of that mode. Just cycle the power on your player.

My Sony 777ES Players' first four numbers are 2200. Does that mean it's version 2.20? Will the chip bring it to V2.53 and are there any sonic improvements?

I just double check and your right, there is no Zero for the first digit. yes you have Version V2.20 firmware and you should upgrade. I dont know what all the differences there were between levels. Sony hasnt published that to my knowledge. I know that the change from V2.40 to V2.53 was only to fix the noise burst problem. And i do know that Sony jumped from V2.20 to V2.40 so there must have been significant changes there. and i know that V2.0 has TOC problems so....

On request I can send the technical service note describing the problem.
"if the ROM version is 2.40 or lower replace with the new version....."
No audible difference at all.

I am working on putting together a kit with an anti-static wrist strap, the proper sized metric allen key to remove the top cover and instructions with photos for installation.
