It was just a dirty connector, it looked a bit dull compared to the other 2 ports so I gave the cable plug a squirt of contact cleaner worked it a bit now its working fine..

I just checked and it seems to be on 30 Hz with no option to change it, I plugged it into the other display port and that does not show the scrambled image on startup and its on 60Hz but if i touch the cable it goes to black screen like the connector is bad .Leave a comment:

Just gone into the bios and all looks like it should, interestingly it seem it only does it from power up not on a restart 🤔...Leave a comment:

Re: high esr on new rubycon caps
So for power supply boards for example if i had no schematic or the capacitor which needed to be replaced, make could not be identified would it always be better to use low esr caps , ?Leave a comment:

Re: high esr on new rubycon caps
Thanks for that info , learnt something new today , I will pay more attention when looking at esr charts in future .
So there must be different charts for low esr ?Leave a comment:

Re: high esr on new rubycon caps
So as a general rule when replacing caps , i would need to see if the caps removed were low esr or not , ?
i just thought i needed to check capacitance value and voltage , .Leave a comment:

Re: high esr on new rubycon caps
The caps i removed were JEC cd110 these are what i used to replace them :

high esr on new rubycon caps
Hi , i just bought some 47uf 50v caps from farnell , the esr of the cap i took out was around 0.8 the new ones measure 1.8 which seems too high , are these a bad batch do you think ? -
Re: CIT 700 w EN60950
not sure if this helps , its the voltages at the ic pins .

CIT 700 w EN60950
Hi , i have been trying to fix the above atx psu ,I think it got quite hot , there was a LOT of dust inside the case and i the fan was not turning freely so may be was stopped .
There were some caps on the output which looked questionable so i replaced them all , i have +5 VSB and that is all .
When i connect it to a motherboard and hdd it works for a second then shuts down , if i leave the green wire and com shorted to power on , it works ok .
It uses a SG6105ADZ ic .
not sure where to go from here ..Last edited by moss99; 11-01-2017, 10:23 AM. -
Re: powered sub wont come out of standby
Hi guys , im about ready to give up on this , i thought i had found something , i noticed when i moved this coil the led would flicker green/ red , i took the capacitor out next to it ,(circled in the drawing ) as couldnt get a reading from it from my esr meter .
Replaced it and after a few seconds the relay clicked and green led , tried it a couple times and seemed ok . but now back to red led again .

Unfortunately apex have said the could not get the driver to this board , typical they have schematics for the good boards ,,Leave a comment:

These readings are with the relay removed , its an earlier photo .
On pin 1 (with the ground probe on center pin of J6) .3 v dc , on pin 2: -12 vdc .
with red probe on pin 1 and black probe on pin 2 i get 4 vdc.Re: powered sub wont come out of standby
