Re: Lg32lb561v power supply(i think?) problem
Thanks for the answer again
I think i expressed myself wrong english is not my first language, sorry , i meant if there's an opening in the leds circuit, should i get sound/tv working and no lights or no sign of life at all? Because looking at some videos regarding this problem they all seem to have sound and tvs working without backlight ofc but mine isnt putting out any sound nor it does turn on
When i plug it the red light blinks and dims to off, pressing the button does not do anythi...Leave a comment:

Re: Lg32lb561v power supply(i think?) problem
I'll check it as soon as i come home
So if one of the leds is bad or there is an opening in the circuit of the leds the whole tv wont turn on at all right?
So i can be sure about the power supply right? If the leds are the problem, changing them would bring the tv back ?
i'm sorry i'm spitting out questions like a machine i'm just interested in how these circuits work

Re: Lg32lb561v power supply(i think?) problem
Its 2 wires to the leds, measuring those 2 wires gives out 80v when leds are connected and 64v when they are not
Led(-) to ground gives 0.00 and led(+) to ground still gives 140v
Thanks again for your time...Leave a comment:

Hi, thanks for the answer!
I still keep those capacitors because i never saw something like that, i attached a pic of those
So is it the led stripes in the panel's fault? i tried measuring while unplugging the connector and it still gives out 140v like if the 117v line broke somewhere on the power supply
If i may ask you a question, would the tv turn on without backlight if i unplugged only that and everything else was fine?
Thanks again!

Lg32lb561v power supply(i think?) problem
Hey guys! I've been trying to fix this tv i had laying around for some time, was wondering if you could help me find the problem because i ran out of knowledge, i'm just a self taught repair wannabe so i apologise in advance for my lack of knowledge
So, one day this tv stopped turning on, only flashed the red light once and then stopping, i took it apart and looked at the power supply, noticed two blown capacitors (the red circled ones) and replaced them, soldering was a bit wonky because one was longer but its the right farad and voltage, still nothing, no turning on no...Last edited by gtanick; 09-18-2018, 11:40 AM. -
