Re: eax64905001 No Pfc Help ?
Hello,
I have got the same problem here- LG 32LN570R, but the board is the same tan the one mentioned in the comments above.
The PSU board is eax64905001 ver. 2.4
I can see the image on the display when I use torch , therefore the Backlight is not getting voltage I believe.
I have measured the voltage to backlight, which fluctuate between 11V -21V
Other voltages on PSU board seems to be right 3,3V , 3,47V , 12V and 24V.
Any ideas which part is causing this ?
Thanks for any help

Re: eax64905001 No Pfc Help ?
I have exactly same problem, voltage to backlight fluctoates between 11-20V. I replaced MAP3202 - but problem is the same ... can you help me to further diagnose fault?Hello,

Re: eax64905001 No Pfc Help ?
Check the 24v diode and the Led mosfet for S/C that could be pulling the 24v low.Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only. Anyone Doing So Will Be Banned Instantly !

Re: eax64905001 No Pfc Help ?
S/c means short circuit if you upload a picture of the top and bottom of your power supply im sure we can pont them out too you unless reece knows the location number alreadyComment

Re: eax64905001 No Pfc Help ?
So on the connector its 0-20v then on the cap which is the Led output filter its 48v ? I dont see how you measured this as the cap goes straight to the connector ? Seems to me like the controller is still bad, or something that feeds it is bad.Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only.

Ahh yes I see my bad I got confused with the other cap. What VCC is going to the mosfet ?Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only. Anyone Doing So Will Be Banned Instantly !

Re: eax64905001 No Pfc Help ?
I disconnected mosfet q801, and i got 46V on led connector and no fluctuation... does that mean that q801 is bad?Comment

Hi there !
I'm having an issue for several weeks with my quite old K70 LUX RGB keyboard. I haven't used it for few months, and once I setup up again my desktop computer, I got several dead LEDs on that keyboard. I tried the Corsair troubleshooting thing (disabling options in iCUE, ...) but nothing changed so I conclude that for some reason some LEDs went in retirement...😅
Decision taken to change these LEDs as I have access to desoldering iron and binocular magnifier, I wrote a ticket to tech support, hopping to obtain the LEDs reference and... They refused to tell me 🙄...10-08-2024, 11:58 AM -
So I use this TV daily as a second monitor for my PC or my Playstation - at one point a few months back I tried to fix the problem - but in the process, I figured out something that works so I haven't posted this for awhile. It is an annoying trick to have to do though, so I decided to post about it to see if anyone could spot what's wrong. It baffles me because it works on it's own half the time.
When I first got this TV, I was told it wouldn't turn on, and of course I did the flashlight test, and the image was there. Also, the red LED on the front indicated that it had power (it... -
Hi all,
I have what should be a simple job but is causing me issues. There are three LEDs (yellow, green and red) on the indicator panel of a solar PWM controller and these have broken off. I need to replace them but I am unsure of the voltage drop across these. I don't want to replace with random LEDs in case they blow.
I took one of the LEDs out of circuit, put 19V across it with a 500 ohm resistor in series and there is a drop of about 13V across the LED, and this seems to increase as I increase the input voltage.
I thought I could just put a resistor... -
i have replaced many leds strips that have changed blue when they are worn
and the new replacements are perfect white
but when fault finding do quantum leds always look blue? -
Hello everyone
I'm new to LED strip LED replacement.
The original LED comes with a single internal LED or chip. I only get at the moment LEDs with two internal LEDs or chips.
I understand that this is due to the tone of the light they emit.
My Doubt is:
Can I use the LED with two internal chips without problem?
Will there be much difference in the picture?
I'm going to replace all the LEDs.
Both LEDs (original and replacement) are 3V and the same size....03-04-2022, 04:03 PM
