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.

    SAMSUNG UE32T5372AU
    by SzymonB
    Hello, I am asking for help. After connecting the power supply, the TV will first blink once and then after a few seconds it will blink 4 times. All voltages on the motherboard are OK, but when there is a cyclical one blink the voltages 3.3V, 0.9V, 1.5V, 12V on the L80 coil also reset. So this x1 blink is like Reset_SYS and then it's x4 blink. Where to look for the problem? There is no Service Manual, I rule out the problem of bios on IC401 because I have already done it. I found descriptions of SOS on the Internet and 4 x blink is Power SOS P Board​ Help. Regards

    VGC-LV1S MBX-199 M820/M830 find the schematics
    by skynet85
    The device is quite old, M/V MBX-199 M820/M830
    1P-0087J02-8011, the video chip flew (artifacts - no picture), removed the old one and installed a new one, but before installing the new one, the area under the video chip sank slightly and Pyataks were found, under a microscope, the contacts were not involved, it was decided to install. Now after switching on there is no initialization, all voltages are normal,
    I couldn't find a diagram, maybe someone will have one. The MBX-199 motherboard was also installed on these models, but I couldn't find the schematics for these either PCG-2E1M...

    HP 455 G7, D0X9MMB8F0, rev.F
    by hopkok
    Hi, I am looking for bioses for HP 455 G7, D0X9MMB8F0 rev F, I found some on web, but different Bios chips and they did not work. Another service erase both chips, so empty chips on board. Customer said, before laptop did not boot at all, just stuck on HP logo. He tried to remove all drives than can access BIOS, updated to last version, but if any device connected back, just stuck on logo. Now he is asking service for files, but with no luck.
    So I decided to ask here if anyone can help. Now laptop completely dead of course.

    My bios chips are on attached photos.

    Samsung 55HU8590 UE55HU8590 maybe one connect box ocb
    by An-klamm
    Hello!

    I have a TV that I can't get any further with.
    It is a Samsung UE 55HU8590 with one connect box.
    When I turn on the TV without the one connect box, the animation on the TV tells me to connect the ocb.
    As soon as I connect it, the TV restarts (panel goes dark) and the TV tries to start continuously (relay on the SMPS clicks about every 3 seconds).
    Since the TV works without ocb, I assume that it can't be the PSU?!
    I have measured all contacts of the one connect cable against GND on the ocb board and there is no short circuit anywhere.
    Is there...

    17PW15-8 blows fuses after lightning
    by Sraros
    Hello,
    I picked this PSU 17PW15-8 from a friend's TV with a burnt fuse, after some days of rain and lightning strikes. The TV was on standby when it happened.
    With new fuses it burns them as well. I checked bridge rectifier, all the TO220 components, diodes and basic caps, replaced IC806 SMPS, and FETS driving the big transformer. I also isolated the secondary circuit by cutting the rails of the FETs to the primary coils. I don't know even know if that makes sense, but I did in hopes to isolate the problem.
    Any ideas what to look for?...

    After flashing bios, no power, nothing comes on ASUS K56CB
    by cyrgh
    Hi
    LAPTOP model: ASUS K56CB (i7-3537u cpu)

    BIOS POST took a long time, more than 30 seconds, it was never like this before. I decided to flash the bios using AFUDOS.exe.
    I downloaded the original BIOS file from Asus site ver205. I used RUFUS to create a boot-able USB flash having this command in AUTOEXEC.BAT:
    AFUDOS.exe BIOS.ROM /GAN

    It read the bios then gave the warning about writing to bios may ruin it. I confirmed and as soon as I pressed the enter key the power went out and it doesn't power on anymore. Even the battery power light does not turn...

    Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
    by chth96
    I have purchased an 100-240v AC/5v 2a DC adaptor from aliexpress,and a month ago It smelled burning when I plugin it powerstrip.
    Since then, This AC/DC adaptor have been out of order.
    But A few days ago,I replace 0.5 watt resistor with 1 watt resistor(1ohm) in this adapter.
    After replacing resistor,It succeed to recharge all of android phone.And When I measure voltage on the two pins of USB port,It shows 5.5v
    Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
    And Is there any possibility that it will suddenly explode as well as to be out...
