Test (experiment) Over !
NO BOOOM !
For good measure now being used in an Australian LG VCR/DVD player - all good so far all day nothing in there getting hot or bothered....its a happy ending!

For this test ..in addition the experiment will be powered up in the middle of the Garage concrete floor!

Good thought - will put in a 750ma fuse...Leave a comment:

Re: SMPS - Can they all handle wide range of Input Voltage?
Thanks for questioning!
I just checked the Varistor V101 and it is the 650V as per Schematic...and this correlates with the one version of the part as seen in the Parts list.
.. been looking over the Parts listed for this SMPS.
Cant see any further gotchas wrt to Voltages as far as I can see.....so once the 450v Cap turns up and installed will test with wooden stick and Dim Bulb....Last edited by ketone; 12-19-2022, 04:30 AM.Leave a comment:

Re: SMPS - Can they all handle wide range of Input Voltage?
For Ref
Uploaded pictures of a 240v EAX39561401 board
and a 120V EAX39561401 Board for visual comparison.
Physical size of Cap C103 looks the same between the two boards...so perhaps the terms 'NARROW' and 'WIDE' seen on the Schematic do refer to Input Voltage ranges?!...Last edited by ketone; 12-17-2022, 08:11 AM.Leave a comment:

Re: SMPS - Can they all handle wide range of Input Voltage?
No stickers - the model is EAX39561401 and they use the same Model number for use across different countries and different Electrical Devices its used in...so not very helpful..perhaps thats hinting that they are all basically the same but who knows!
The schematic I posted highlights the different Capacitor C103 as a difference between locations.
Will see how she blows! I mean goes
after changing the Cap....

Re: SMPS - Can they all handle wide range of Input Voltage?
Well yep I think so.... will rig up a 25/50watt dim bulb/load lamps in series with the power supply. Still Im not sure that would save any damage...maybe less smoke !...

Re: SMPS - Can they all handle wide range of Input Voltage?
I just spotted that Australia uses the 63uF 450v for the same module - spotted from a picture of one on sale in Australia - ebay.
Still hard to ascertain if any other differences from a picture.Leave a comment:

Re: SMPS - Can they all handle wide range of Input Voltage?
Thanks Per
Yes currently C103 is a 250v 150uF - so "NARROW' and lower voltage.
I could change it easily for a 450V 100uf 'WIDE'
or 63uF 450V cap..
Not sure what 'WIDE' gives me as in what input range it then allows.
the 63uF is meant for S.AFRICA so I know its supply voltage is 230V...pretty close to Australia's 240V supply.
Then as you say there could be differences not listed in the Schematic......Last edited by ketone; 12-17-2022, 03:53 AM.Leave a comment:

Re: SMPS - Can they all handle wide range of Input Voltage?
eccerr0r thanks for your thoughts!
Is it possible in anyway to ascertain if the module is able to handle a wide range input voltage or not?
FWIW here is the Circuit from an SM....it does not say specifically unfortunately.!
EDIT
I noted from the Schematic it states C103 can be either 100uF 'WIDE', 150uF 'NARROW', and 63uF 'S.AFRICA, INDO, CIS' - wondering what 'WIDE' is referring to.
At the moment C103 is a 150uF so its NARROW.
Voltage in S.AFRICA, INDO, CIS'...Last edited by ketone; 12-17-2022, 03:42 AM.Leave a comment:

SMPS - Can they all handle wide range of Input Voltage?
Hello Forum - See I got this SMPS Module!....its sourced from a US device and I'm in Australia.
As we know Supply voltages in Australia 240v Versus 120V US.
The Model of the SMPS is EAX39561401 and is used in LG and JVC DVD/VCR Player/Recorders...same model is used in both Australia and US...but perhaps they have differences??
What's the chances I can use it in Australia - plugging it in to 240v instead of its origin country at 120v?
Is it expected that most SMPS in such devices would handle between 100-240V by default?
How can I... -

Thanks Pete
The unit is 2003 so you are spot on.
What decade/years did Snap In capacitors start being used? do you know... curious and thinking as the unit is so old they might be Radial Through Hole Caps.!?...Leave a comment:

Ty Mariushm very helpful!... I will have to check to see if a Snap-in will fit...will remove an existing Cap and have a look. Cheers ...

CHEMI-CON 4700uF AH Alternatives ?
Hello Forum
Looking for advice ... need to find an alternate Capacitor so I can replace four:
Bulging Chemi-Con 4700uF, AH Series, 50V DC, 85c, 28mm x 45mm Radial Electrolytic Capacitors installed in a decent Audio Amplifier Power Supply.
I have searched for anything more about the 'AH' Series ..but found nothing...they must be a special for the Amplifier Im thinking.
What is the best Capacitor that I could replace these with ?
Thanks in advance. -
Re: 60PX950 No Picture, Test Pattern Ok, Main Board Failure?!
Updating this issue: As expected it was a main board fault...managed to obtain a used main input board and Voila..picture is back!
If this happens again..will look at BGA replacement..link BGA Replacement/Soldering Video

Re: 60PX950 No Picture, Test Pattern Ok, Main Board Failure?!
As a side note to this problem... it occurred the morning after attaching an old wii console to the tv using a third party component video cable. I didnt think it could be possible that the two somehow related. But! the backup TV was working fine until the old wii console was again connected...! This time the fault is different....more a solarization of the picture! which increases the longer the tv is on...this now happens on all Inputs including DTV and is seen on the menus...I assume this could be a Mainboard issue...Leave a comment:

Tried oven trick 8 minutes at 195c ... no go... is it possible to change the BGA chip? .. as the main board is no longer available.Leave a comment:

60PX950 No Picture, Test Pattern Ok, Main Board Failure?!
Hello all!
Ive researched previous threads and tested my 2010 LG 60PX950 TV... jumping between R51 an R52 on the CTRL Board...test patterns OK.
No video on turn on...TV LED acknowledges remote presses.
So guessing with these results its one of 'those' main input board failures!?
The main input board is no longer available from LG...(must have had a lot of failures I guess!)
So no boards available means we are now looking for anyone who can component fix the board...anyone had any luck ! or have any clues !?
I noticed that my...Last edited by ketone; 04-09-2017, 11:49 PM.
