Re: Replaced Caps and made things worse...

After my previous post I decided to go back and review some of the earlier posts by yourself and others trying to assist.

Unless you can test all of the electrolytic caps with an esr meter (a must if you are repairing smps) you will be forced to replace them all - as has been suggested by others. Also, if you have replaced some capacitors with new ones then don't extend them on fly leads.

You didn't post the model of your TV but that may not be too important if this psu is used in various brands and/or models....

Re: Replaced Caps and made things worse...



It is rare for transformers to fail on smps. Usually, a failed transformer will be indicated by severe charring or dark colouring of the windings and perhaps cooked pcb pads. Your transformer is in pristine condition and it is not the main switching transformer but more likely a feedback isolation transformer.

To me the problem seems to be more that your inexperience with smps repair means that you are plucking at straws or fishing in the dark for the failed component/s. Unless you can get a schematic of the...

Re: Antec TruePower380 & the Fuhjyyu Syndrome



That is a reasonable suggestion and I had considered it and then abandoned it. My reasoning (based on many years in electronics design and repair of smps) is that while the lower voltage will provide a suitable margin above the working voltage, the physically smaller size of these caps means they have less volume of electrolyte. As it is, manufacturers are constantly trying to reduce the volume of their capacitors in order to occupy less board space and this means there has to be some compromises. Less volume = less...

Re: Antec TruePower380 & the Fuhjyyu Syndrome

I know this thread hasn't seen a new post in 3 years but I thought I would add my threepence worth (apologies to those non UK or british colonial descendents)

I built my pc back around 2006 using an Antec desktop case, Antec Truepower 380 PSU with an ABIT AA8 Duramax 3rd Eye motherboard (with LGA775 P4 3GHz CPU). and it has generally performed flawlessly (apart from a few minor problems such as replacing a noisy north bridge chip fan and graphics card cooler fan).

Last week I found that when trying...
