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.

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.

How are you getting on with the instructions? I have just bought the chip and would be garteful for the info.
🙂
I don't how well this will appear, I've just copied and pasted it from the technical bulletin. BTW, the chip is in stock at Sony and would cost £71.44 in the UK.

The chip costs less in Cyprus and takes only 1 week to procure - about GBP60 including VAT

Price is good, but a week is slow! - Sony spares in the UK take two days, they are flown over from the European spares department in Belgium by DHL.
Still working on the instruction sheet. Adobe is not co-operating with me and i am having to reformat the photos as the file was too large at first.
Instructions are very simple however. Make sure to unplug power.
1- remove allen head screws in outter rim of top cover.
2- lift cover off. may stick to rubber bumpers. may take a little effort to lift off.
3- Lift cover and unplug cable to door assembly. remove top cover.
4- Locate IC716 on the Main Board just behind and to the left of the front display.
5- Slide black plastic IC cover assembly to the left. may require some careful effort. Beware of small parts on PCB in the area. cover will click. then be free to lift off.
6- remove IC by lifting straight up. Make sure to note Orientation by Dot on the face of the IC.
7- Replace IC. Make sure to place new IC in the same orientation. Gently push IC down to seat fully/
8- Replace top IC cover. Push down slightly and slide to the right. Cover will click into place. May take some effort gently
9- Replace top cover, make sure to plug cover door cable back into motherboard.
10- Plug in power and Test. If Display comes up, your OK, check firmware revision by pressing Text on the player and Check on the remote at the same time. 0253xxxxxx should come up on the display. power off and replace top cover screws.
Pretty simple! the real deal coming soon!

P.S with exchange rate and shipping. how does my price of $75.00USD compare??? I would be willing to flex slightly on price to match. As i have mentioned in other post's. i am not doing this to make a profit so much as to recover my cost's and provide a service.

Better; if you use USPS global priority you should be able to do it for $90 ie GBP50. also it is a hassle to order in UK because you have to go thru' inefficient middle men.
Suggest you do the sled motor as well worldwide.

Global priority shipping adds $20.00usd for a total of $95.00, I cna drop the price to $90.00 with shipping no problem.
I will look into the sled motors.

Just done it. Difficult to tell if the black cover has clicked back. Arrow on cover is on top to the left. Right??
