Hanns-G 19" turns off. PSU overheated and bad caps

Re: Hanns-G 19" turns off. PSU overheated and bad caps

I get them from Digikey or Mouser who I understand ship internationally but as you are in the UK then RS Components or Farnell may be a better choice for you.
Badcaps.net also ships to some other countries but the grades here will far exceed your actual needs.

Best take that advice from someone that buys caps often in the UK.

Also whats the difference between Panasonic FC series and Panasonic FM series?

[PCBONEZ]

Re: Hanns-G 19" turns off. PSU overheated and bad caps

FM are higher grade than FC. [Better ESR/Ripple ratings.]
FC is good enough for your application.
Would be no problem to use the higher grade, just probably cost more.
Panny FJ is common on ebay and better than FM. [FAR better than needed.]
Pansonic FC and FM don't mind hot places like power boards.
Not sure about FJ that way. I never see them used there.
-
I don't remember ever seeing Panasonic fakes but that doesn't mean there aren't some.

Here is example of what I mean by grades using [ESR/Ripple] specs:

All are 1000uF 10v 10x16mm
FC .068/1050
FM .026/1790
FJ .019/2000

Less ESR is better and more Ripple is better.

Re: Hanns-G 19" turns off. PSU overheated and bad caps

Filter caps are used to send [short] ripple [noise] to ground.

In layman's terms:

ESR is a measure of the caps 'resistance' to sending ripple to ground.
[Resistance is not the technically correct term but easiest to understand.]
- Less is better.

And 'Ripple' spec is a measure of how much Ripple it can send to ground without overheating.
- More is better.

-> No

Look for:
Rubycon, Panasonic, Sanyo, Chemicon, Nichicon, Elna, Hitano, NIC Components.

~~~~~

There are several dealers on eBay that sell counterfeit caps.
Counterfeit Sanyo, Chemicon, and Rubycon are not uncommon.

.

The dealer Scenic suggested is mostly a good source.
I have bought there a few times.
They do sell some crap brands but they don't hide the brand's name in the ad.
They may have some Sanyo fakes and not know it. It's very hard to tell in ad photos.

Fake Sanyo:
[Color applies to WG series only]:
The gold color is too dark and too solid. [But probably can't tell in photos.]
- Real Sanyo WG have a lighter gold color and a 'washed out' looking gold stripe.
-
Real Sanyo have a K shaped vent stamp but not the same K as Rubycon's.
-
The "V" standing for voltage is the same height as the numbers on real Sanyos.
On the fakes the V is shorter than the numbers.
.

These came from eBay.
I suspected the 2200uF were fakes so I sent samples to Sanyo for testing.
I was right.
The 2200uF in the photos are fake. The 1000uF is legit.
(Note color, The 'V' next to 16, and the vent shape.)

Seller is still selling these caps but he rubbed the Sanyo markings off.
Doesn't state a manufacturer in the ad anymore at all.

Re: Hanns-G 19" turns off. PSU overheated and bad caps

haven't bought any Sanyos from him, so i can't tell much about that.
i've only bought pannys rubys and nichis there (and a few NCC input caps)

[PCBONEZ]

Re: Hanns-G 19" turns off. PSU overheated and bad caps

I didn't get the bad Sanyo from him.
Was from someone that uses at least two accounts named like Modern-Life____

[Scenic]

Re: Hanns-G 19" turns off. PSU overheated and bad caps

oooh.. that guy... IMHO he's only selling fakes or poor quality caps.
most of the time he doesn't mention a brand at all and/or the pics are useless for identifying them.. -.-

edit: also from this seller.. Rudoycon *lol*

Any news on the LCD, baileyboy?

[baileyboy]

Re: Hanns-G 19" turns off. PSU overheated and bad caps

Hello
I have replaced all the caps you recommed and the monitor is still not working. What do you suggest replacing next. The problem is exactly the same.

Post relation of the originals and the replacements. Also, measure voltages in the pins of the output - they are marked easy for testing. Check the 5v and 12v outputs (that they are close to that and that they are stable too). Post the results. I'm messing with a K717 that has the same PSU so maybe I can help. And by the way, that looks more like a Proview/Sylvania/KDS/MAG than like a Hanns-G. Please post a pic of front or back of the monitor to confirm this (all the Hanns-G that I've seen so far have the model stamped on the upper right front bezel, as well as in the label on the back).

Re: Hanns-G 19" turns off. PSU overheated and bad caps

The sticker on the back is mainly in chinese but there is the code AG172DP. However this is a model no. for a 17" not a 19" and this monitor is 19".

Hello

I have a Packard Bell Virtuoso 190 P/N 6969280000.
PSU 200-000-170DTL1 Version A+
I replaced C209 - C210 - C211 - C212 - C223 - C224 470uF 25V C219 220uF 25V
The screen works for a short time.
What is the voltage on the backlight lamps.

Re: Hanns-G 19" turns off. PSU overheated and bad caps

I also replaced IC204 AZ7812T for a MC78T12C
There are 4 connectors are that 4 separate lamps?

Although we're reviewing here what it looks like a Hanns-G 19" with the interior of what it looks like a Proview 17~19" with a Model number of a Hanns-G 17" that has that PSU (or one almost the same, also from Mirage), you should take a look at this thread.

And as of the V going out from inverter to lamps, must be between 500 ~600v.

Resolder transformer T1

I bought one and bought two more 6 months later. All 3 have the same CapXon caps. The first one hasn't blown a single cap. The two later ones 10 serial numbers apart died.

These often hiss before dying completely. Fortunately no bad inverter transformers in the mix. A few caps and a little solder and they are up for another round.

This power supply has an adjustable current sense.

Re: Hanns-G 19" turns off. PSU overheated and bad caps

You've put in a complete mish-mash of OST, Rubycon, Teapo and all sorts.

Not how I would have done it...

I've done it twice in out-of-stock-and-time-urgent conditions with Rubycons and Panas FC (ones in the inverter section and the others in the primary/secondary side, in groups).I prefer not to mix, even for aestethic purpouses (I took pictures of almost everything I repair), but sometimes you just have to do what you can with what you have .....
Not recommended but it worked for me.

Re: Hanns-G 19" turns off. PSU overheated and bad caps

Most caps are in parallel. The likelihood of two different cheapo brands failing is low. These will last another 4 years at which time they will be set on the curb working or not. If they are still valuable then they will be recapped again.
