Forum Rules *ALL NEW MEMBERS, PLEASE READ!! UPDATED!!*

First and foremost, Welcome to the Badcaps Capacitor Search Engine & Forums!

New members that have activated their accounts have limited access to certain features of the site until established. Members with zero posts have no access to the private messaging system. Also, members with zero posts may not edit certain profile attributes, such as signatures. New members also may not create new threads. However, new members with zero posts have full access to all technical information contained on this forum, and that also includes attachments (images and files that other members have uploaded), and new members that have activated their accounts are free to post replies to existing threads. If you wish to create a new thread, the fix is simple! All you need is ONE post to be able to have full unrestricted access, and that can be simply posting an introduction of yourself or say hello in THIS THREAD. This may seem a little strange, but it helps keep spam and abuse curved. Please note, that it may take up to one hour from your first post for the limits to be removed. If you make a post and don't immediately see the restrictions gone, be patient. The promotion system updates every hour.

Please complete your profile after making your first post, with your name, locale, and other info. It's nice to know members on a first name basis, and know where they're from. Makes for a much friendlier environment!

Posting rules for this forum will be STRICTLY enforced by myself as the owner/administrator, and my moderator crew.

Badcaps.net IS A BUSINESS!!! If you are a servicer, service center, or vendor of any kind in the computer/capacitor industry, you are NOT permitted to advertise, link, promote, or plug your business on this forum in ANY way! NO EXCEPTIONS!! This includes asking for "donations" in exchange for BIOS passwords or tech advice for anything! If I see you doing that, your post will be edited or deleted, and you warned. If it happens again, you will be banned. The only exceptions are the references to the companies quoted in the FAQ which the administration have added for the convenience of those around the world who have difficulty to source caps for their repair.

This also includes using this forum's private message system to solicit business. Members, if you receive a PM from anyone offering repair services or components, please alert me immediately! Myself or any of my moderators, will never private message a user soliciting business, for Badcaps.net, or any other servicer/vendor. If you PM me about repairing your device, I will reply and take care of you, however, I will not message you first.

------------------------------------

Posting rules:

This forum was created to be a technical support forum primarily for the do-it-yourselfers who choose to repair their own boards. Any and all technical questions are welcome!

1) Please use the SEARCH feature!! Your question may have been answered in another thread! Please search first and see if it has!

2) When posting a technical question, be as detailed as possible in your thread. The more information we have about your specific problem, the better we can answer your question.

3) Please use COMPLETE sentences, punctuation, and grammar! Nobody is perfect, hence, a spelling error on occasion is no biggie. However, posts/threads that are unreadable will be deleted. This includes any and all forms of 'ebonics', leet, chatroom jargon, and 'text message' shorthand and slang. This forum is not a chatroom/text message, please use full words and complete sentences.

4) Keep discussion on topic!! DO NOT HIJACK THREADS! It's easy to do (I've done it myself a few times...) Lets try to keep it down to a minimal!! If you have something really off topic, that's what the lounge is for!

5) Keep things civil! There will be no tolerance for flaming, bashing, hateful remarks, racial remarks, adult material of ANY kind, and so on.

6) THE LOUNGE RULES! The lounge is a place for off topic chit-chat! If you post something that might be considered questionable or something you don't want kids to see, or something you can't view at work/school, etc, please label that thread *NWS* or NOT WORK SAFE in the thread title as a warning. The Lounge is NOT moderated, anything is welcome... Feel free to post rants, jokes, cars, hot women (remember the NWS warning in the title), or just about anything within reason. It's an open forum! Please refrain from participating in political topics if you have thin skin, they can get heated sometimes!! Remember that we have members here from all over the world, with many different views and cultures. Political debates can turn really ugly, and really fast, and if they degrade to personal attacks and useless banter/bashing, moderator action will ensue. I want this forum to be a safe haven for technical discussions from all walks of life, so lets keep off topic discussions civil and friendly.

7) Spamming and spammers will NOT be tolerated or accepted in any way, shape, or form! Spam bots are instantly and permanently banned, and their threads deleted! The mod crew is really quick to zap spammers, we typically pop them before they even get to post. This also includes regular members as well. be courteous and not post spam. This includes links to off-site information that's not relevant to the thread at hand. Do not plug other websites, forums, or businesses in your signatures. You may do so in a thread if the off-site link you're posting is relevant to the topic, but otherwise, don't do it. If you see a thread which clearly a spam bot posting that we have not removed yet, DO NOT click any links in it!! Simply click the 'report bad post' button, and it'll be taken care of, usually within minutes.

8) Account removals & closures: Since no personal information is given in the creation of your Badcaps.net Forum account, requests to remove and/or delete accounts will be declined. Any requests for removal of threads & posts you created will also be declined. The reason is the missing posts can/will leave threads incomplete and fragmented. For the threads to be of help to others later on, information can't and won't be missing. However, if you inadvertently posted personal identifiable information in a post (such as an email address, real name, or phone number), please contact a staff member. In those cases, the post may be edited or removed, at the staff members discretion.

That's about it for the rules, the setup here is pretty loose. However, if you're caught violating any of the rules above, here's what will happen:

First offense: Warning by me or a moderator
Second offense: Banning for 1 day
Third offense: Banning for 3 days
Fourth offense: Banned permanently.

If you do something really dumb, or are just a troll, I will skip the warning and the temporary banning, and ban you permanently!

The rules are pretty cut and dry... However, if you have any questions about this policy, feel free to contact me.

        I was told that you scan down until the FFFFF HEX starts then you should not have any data after where the FFFFF HEX ends. But this so called known good has data before and after. I am using HEXHD. You using Text string or Hex Value for searching 001c?

            Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

            Yeah i found that already. That is the Model and Serial number of the ps5. I did a compare for differences and found some other entries that didnt match across two BINs but I think its irrelevant. Trying to find where entry where the motherboard is paired to blue ray daughter board. Any ideas on that?

              in theory there should be:
              model,
              serial,
              ethernet mac,
              wifi mac
              and maybe the cypher-key for pairing the optical drive.

                Yeah the cypher key is the hard one to find. I remember with the PS4 there was a extractor app that would pull that specific info and make a small BIN to edit with a hex editor.

                  the only way to find it is to compare several dumps and identify the other stuff so only the drive key remains.

                  unfortunatly when people do post dumps you dont know the serial/mac's etc to look for them in it.

                    Well i ordered 10 Winbond 25Q16JV chips from Digikey. Plan is to flash backed up bin to new chip, re-solder and pray. Haha But i will keep digging at these entries and where to find them. Will try to find a common placement. Thanks stj!

                      Update: I erased and flashed the original bios chip with original BIN. No change. Still waiting for new bios chips to arrive. Anyone have a diagram they have obtained or created that maps out all the known good board voltages for EDM-020?

                          Stj,
                          I will check the BIN I backed up later today for that entry. Have you personally been able to find any diagrams of board voltages. I may make one for the board i have. Cod3r has some great vids showing the voltage power rails. But i would love to open up a pdf and be able to reference on the fly. I may buy a psn suspended known good working board and take the rail readings from there. Just curious. Thank you.

                            i have no idea, never even had a ps5 on my bench.
                            i'm just interested in documenting/decoding the syscon content for future uses.

                                So while I wait for the new bios chip to arrive. I decided I would take the thermal cam out one more time. Here is a look at the EDM-020 powered up. More to come. Need to document part numbers heating up in pics.

                                  There are (2) 3219A chips on the board that appear to be heating up. The first is located left of the APU and the other is located just below the bottom left RAM chip. If i had a known good board i could see if these chips getting warm normal or not. Anyone else have a EDM-020 board? Maybe we can work together to fix two units?

                                      I am wondering if they are worth replacing. Dont want to go down another rabbit hole. What you think?

                                        They should get warm, check the datasheet for output voltages.

                                          Oh sorry i missed that. 40 celsius to 85 celsius. Well the highest i have seen is 60 celsius on the chip to the left of the APU. The one below the RAM chip is running low 40's to 50.
