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.

      Re: Which Eprom programmer to buy

      Guys I'm reviving this topic to ask if in your opinion buying a TL866ii plus is a good move considering I only need it for TVs; or which one would you buy?

      Also I found on a polish (I think) website a "homemade" programmer called NANDLite which is only for TSOP48 nand. Does any of you have experience with it?

      Right now I'm using a ch341 which woks great but it can't do nand and I'm seeing nands more and more even on non-smart TVs so I guess I'll have to be prepared.
      TiA!

        XGECU has a new universal progrmmer along side the TL866II called T56. It uses the same software as the TL866II too. The T56 is faster and it also does more chips.

          T56 is 3x as expensive -if you need 48pins then it's a bargain compared to the competition though.

            Thank you both for the answers.

            So you recommend the T56 over the tl866II

            On the aliexpress page there is a link to a compatibility list, right now I want to try programming a H27U1G8F2CTR that I have on a LG tv but it's not on the list, so how does compatibility works?

                That is the list I searched in and this exact model is not present so I googled a bit and found that if you find a chip that it's essentially the same you can program it anyway (what I found was a screenshot on a forum of a guy that had 2 nand and checked them with a SW and the only difference he found was the "generation" of the chip, so older and newer model), the question is how do you do that? You can't possibly manually check 250k datasheets..

                  Re: Which Eprom programmer to buy

                  start by removing the letters from the front - they usually indicate the maker.
                  so you have 27U1G8F2CTR

                  next remove trailing letters - because they often indicate stuff like revision or package material
                  so you get 27U1G8F2

                  then search:
                  and you find in the list - HY27U1G8F2B

                  so then you just need to compare 2 datasheets to see if the parts are compatable.

                    So same as SPI Flash, perfect. Thank you a lot for all the infos!

                        Re: Which Eprom programmer to buy

                        Anyone knows what's the main controller chip inside EZP20xx programmer ? Of course might be unknown (covered in plastic) as often with chinese USB devices.

                        I personally like CH341A with AsProgrammer software. That software allows adding unknown chips (xml file), it allowed me to succesfully flash M45PE20 short time ago.

                                Differences between EZP2019+ and EZP2023+
                                EZP2019+ uses a CH552G microcontroller, EZP2023+ uses a CH554T microcontroller
                                EZP2019+ on the board says "EZP2019+ V1.0", in EZP2023+ on the board it says "EZP2019-2"
                                Due to the fact that the microcontrollers are different, the layout of the tracks is different, but in fact the circuit is the same, taking into account the identity of the ports themselves on the microcontrollers.
