    Problems with Abit KT7A

    My PC with the Abit KT7A mb and duron 900 cpu worked well for about 2 years, but has later started having random lock-ups. Also sometimes when I tried to open the cd-drive it stopped in the middle for a sec and then continued opening. Seems as if it had something to do with power. It quickly kept getting worse and worse, and now it won't show anything on the monitor, usually. Nothing happens when I turn it on, other than the PSU and CPU fans start spinning. Sometimes (rarely) I can get to the bios, but it will lock up after less than 30 seconds.

    I've tried to swap all other parts except CPU and MB (no spare ones of those), for no effect. It's been tested without the case too.

    I've also checked all the capacitors, but haven't spotted anything abnormal. The MB has jackcon capacitors, which are on the bad cap manufacturer list on this site. Could these problems be caused by bad caps, and is there any way to find out which ones could be bad if it can't be seen with eye.

      Yes, the problems could be caused by bad capacitors. I have an Abit board that wouldn't POST at all until all the capacitors (Jackcon and Tayeh) were replaced. Other people have reported problems similar to yours, which have been resolved by replacement of the capacitors. Capacitors can be checked using a capacitance meter, but also need to be checked for ESR (lower is better; this function is available on better meters). The likelihood is that you'd find out the capacitors were bad. The cost of replacement capacitors (available through this site or any of several vendors) is likely to be significantly less than a new motherboard. Replacement is not difficult; however, if you are concerned about doing it yourself, there are several people on the site that can do it for you.

          Significantly less where?

          Socket A boards are dirt cheap now in the US...
          Ya'll think us folk from the country's real funny-like, dontcha?

              AA and AAA battery charger capacitors?
              by slybunda
              hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
              it has inside:
              2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
              2 x 470uf 16v LZ105c branded as G.Luxon

              not heard of these brands are they any good?

              iv attached photos of the charger and the board inside for an idea on the type of...

              Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
              by sam_sam_sam
              I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

              This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

              After all of...

              laptop hp g72 b52sf screen problems
              by jean luc ferre
              Hello,
              on this laptop hp g72 b52sf i have screen problems as you can see with the photo joined in attachments.
              the used graphic card is "intel hd graphics" and the id of the integrated screen is : "monitor/SEC3354".
              i verified the driver of the péripherals and they are ok. i verified the definition and settings of the graphic card and of the screen : definition 1600x900 and refreshment frequency :60hz. (they are the sames for the graphic card and the screen).
              i don't understand the reasons of the white stripe at the bottom of the screen below the task...

              Are there any datasheets available for Elna RJG capacitors?
              by Ady2017
              I have a 2007-era Panasonic VHS combo that is full of of Elna RJG capacitors. I am trying to test the capacitors to diagnose the machine and then select replacement capacitors but I can not find any datasheets for them. I did find a Elna catalogue from 2007-2008 but there is no mention of this capacitor series. Where these specially made for Panasonic and so not made available to the public? Any ideas what to find out what the ESR values should be without the datasheets? They are all between 10V and 50V and 47uF and 1800uF. None are leaking or bulged but I know that they need to be tested to be...

              Samsung UN70tu7000wxza no standby light, do I have bad capacitors?
              by ctroxtell
              I picked up a 70" Samsung UN70TU7000WXZA. The original owner said they were watching it when the power surged and knocked it out. I pulled the back off the TV and disconnected the main board from the power board, and the LED backlight came on, which I was told meant the power board was good. When everything is plugged in the standby light will not come on, looking at the main board BN94-17775A with a thermal imaging gun I can see one of the chips labeled 3202 is 251 degrees F just sitting idle. I found a replacement board, BN94-16115X; this board has the same symptoms, except it is a different...
