Re: Vizio vp322 hdtv10a

this is all beside the point though if u have found the best all around caps to get which are the panasonics...
do they stock them here and im just blind?

Re: Vizio vp322 hdtv10a

please i want to order before i go to bed and its already 3am... sleep is so inconvenient sometimes!!!

Re: Vizio vp322 hdtv10a

I don't know if badcaps.net stocks them because I've not ordered from them before, being in the UK. Tried digikey? Badcaps.net store is more for motherboard repair than power supply repair.

Re: Vizio vp322 hdtv10a

ahh ok thanks ill look em up there

[triplefour]

Re: Vizio vp322 hdtv10a

almost there but im having trouble finding just one of these caps:

the samwha 16v 100uf 11mmx6.3mm lists impedance as 0.15

but in the panasonic fc and fr series the only equivalent is 0.3 impedance
the rubycon yxf is 0.4
and the panasonic fm doesnt exist in 16v 100uf apparently...

is .3 ok compared with .15 even though thats double the impedance?

Re: Vizio vp322 hdtv10a

For a small 100uF yes that should be fine. Significant ripple current not expected.

ok this is the cart ive got picked out. should anyone else want to save time

Re: Vizio vp322 hdtv10a

think ill go ahead and order double so i can fix both of em one time

Re: Vizio vp322 hdtv10a

ahh nooo.. why doesnt digikey accept paypal?? i got my wallet stolen recently and i had to change my bank card so i dont have the new number yet....
laaaaaaame~

[tom66]

Re: Vizio vp322 hdtv10a

Because PayPal take 3% extra... AND they don't let merchants pass this cost on (as e.g. a PayPal payment fee +3%), so they have to roll it into all of their payment methods.

Re: Vizio vp322 hdtv10a

paypal takes 3% more than the credit card companies? crazy!

Yes, a leach on the industry IMHO...
Merchants SHOULD pass on payment charges to the customer (and no more, just the exact rate)
That way there would be competition for these companies to offer lower interchange fees...
Right now it's actually ILLEGAL for a shop to charge extra for using a credit card, what the hell?

Re: Vizio vp322 hdtv10a

well i guess u just gotta factor it into the price... cant someone make a new paypal thats cheaper? payfree anyone??? that'll be the day

Re: Vizio vp322 hdtv10a

its been a crazy week. finally got it together and ordered the caps from digikey. crossing my fingers!

Re: Vizio vp322 hdtv10a

wouldnt u know, i found another one of these TV's with some minor screen issues but all the boards are fine. swapping out the working psu I know now that my other 2 tvs are just fine...when the parts come in ill have 2 perfect ones and one with a minor screen issue (burn in) is there any way to reverse the screen burn in on plasmas?

Re: Vizio vp322 hdtv10a

and why is "too low" ESR bad? i thought lower ESR was better?

It depends on the circuit and what function the capacitor is performing there.

Low ESR is good for switching power supplies because it means the capacitor dissipates less ripple as heat, meaning it stays cooler and thus lives longer.

But switching power supplies are tricky circuits to design, and require rather tight tolerances on components. You already know what happens when the ESR of a capacitor gets too high, or the capacitance reduces. The PSU outputs are not filtered properly anymore and the power is full of ripple and noise, which results in improper circuit operation or even damage to the load.

In some cases the PSU becomes overworked trying to compensate for these bad capacitors and can itself become damaged due to overheating etc.

If the ESR is too low, a similar thing can happen. Filter and feedback circuits which were designed for a capacitor above a certain ESR value do not operate properly when the ESR is too low. This leads to improper PSU operation, stressed components, and ironically, higher ripple and noise.


So when you are selecting new capacitors, it is a good idea (in most cases) to choose ones which have an ESR value close to the originals. It does not have to be exact, though, and a replacement with a bit lower ESR than the originals is preferable to one which is higher.

Re: Vizio vp322 hdtv10a

I need to find me one of these, as far as burn in repair... Not likely fixable but you can put it on tourch mode and run a pixel shifting or a screen wipe for a hour a day.

Disney WOW bluray has all this stuff for TV/Audio calibrations and what not.

Re: Vizio vp322 hdtv10a

The picture is really nice I can only see the burn in when the screen is blank but lit..what is this torch mode? And what does Disney have to do with all this? Thanks

[Shinju]

Re: Vizio vp322 hdtv10a

Torch mode is vivid/dynamic setting with contrast/brightness/cell light/ or what ever makes the screen bight as possible (all settings set to max).

Re: Vizio vp322 hdtv10a

...so wait...i have to get a blu ray player and this disney disc...and it can fix the screen burn? is torch mode something i can do without that? how do i access such a setting?

err is it just setting everything to max brightness and displaying a white screen?

for how long?
