psu mlcc
i came across dead seasonic prime psu with shorted mlcc caps on the modular board, this is the third time i encounter this problem, i usually just removed the shorted mlcc and not replace them since theres a lot of caps around the psu i used to think those mlcc probably does not matter much, i have no equipment to test or proper knowledge for this. i just reuse those psu on low end machines. but few days ago one of the machines have its 2 sticks of ram died, it keep on getting blue screens. 2 sticks of ram died at the same time, its probably something else and not just the ram. in the past when... -
PSU selection
my computer recently acted strange, random freezes , video card died and next the harddrive died, and now i have parts left the processor,motherboard and i still have 160 gb old hardrive around
a friend of mine offer 2 psu for 40 usd, both used for less than a month, ( hes paranoid that those psu would kill his system )
now i have both psu on hand and im paranoid also if these psu would kill my remaining components
1.huntkey greenpower 550 watt? (6550hg) psu
2.huntkey APFC 700 watt psu ( similar components to huntkey win7 )
which of these... -
Re: Weird PSU
i removed c33 to take a closer since its different with the other caps same brand but with different label color (blue) , also the capacitor in 5v rail is also different its OST i guess this psu have previous capacitor failure in 5v and 3.3 v rails and been replaced. im using the psu right now and its working fine tested played heavy game (metro LL) for almost 3 hours and only a very little drop in 12v rail 11.988 to 11.877 my only concern right now is those caps that are replaced if they are in correct specs. also i really dont know where to find good caps in my area...Last edited by jescolta; 06-06-2013, 10:17 AM. -

psu brand is powerstation2 ps2-450
internal number is mtp5002

im using it now and system is stable only one thing i noticed system now runs hotter than before
my main concerns is maybe this psu is not really 450 watts at all or... -
Re: LCD Problem when hot
by inspecting more the main problem is the lcd panel , it is not flat , it is curved in the middle, which causes massive back-light bleeding, i reduced the bleeding to minimum by adding layers of tape each side of the lcd screen adding small gap between the lcd and the light source , the power board uses not just crap capacitors but the super crappy one , i doubt if it will even last a year running 24/7.
thanks for those who tried to help me

Re: LCD Problem when hot
the transformer is the one that's getting too hot , sorry i cant take pictures i dont have a good camera device , but the problem is like " light bleed" or "lcd bleed" on the area that's getting hot.Leave a comment:

Re: LCD Problem when hot
im also thinking of adding a small fan , but that would cause dust buildup and yes its running really hot , i guess the components used are underrated , im planning to put a thick sheet of metal under the power board , with some insulation . will that prevent the power board heat to reach the lcd?Leave a comment:

LCD Problem when hot
hello i recently purchased a 23 inch led tv and im using it now as computer monitor, i got this thing for so cheap that i agreed that it doesn't have any warranty at all , they sell all their stuffs since they are closing their business.
the only problem this tv have is when it is used for long period the power board heats up a lot and the part of the lcd screen which is underneath this very hot power board changes its color , its getting brighter than the rest of the screen and looks like being color inverted, its more noticeable when i play games with dark areas, any way to fix... -

Re: PSU overloaded?
its working fine no reboots no stability issues
12 v reading 11.99 to 12.04 v dropping to 11.93 at heavy usage
5v reading 4.99 to 5.02
i opened the psu today
2 caps are leaking some kind of oil on its top
i also noticed the fan is running very very slow i cant even feel the air coming from the back of the psu
replaced the fan with .15 A 12v fan and it wont spin
voltage from the fan controller in the psu is 4.6v even heavy loaded - so i removed the thermistor and tested with multimeter it change resistance when heated...Leave a comment:
