Lg43UJ620V horizontal line
Hi guys I have this tv and in one side of the pannel it shows some line i also cleaned the camble notting, although I found an smd capacitor on the pcb (there's no tcon on this model) but I can't find the same model thanks -

Hi thanks for your reply, the problem is that the front pannel don't work at allπ dedicated knobs and buttons nothing only on and off. Thanks...Last edited by labello; 02-18-2025, 10:08 AM. -

Hi someone can tell me how to check the wattage on that resistor, thanks...Leave a comment:

Hi I'm already doing what you say , first when I plugged in the camble, it going a little spark then the power supply going on protection (suppose short) then it seems that chip and a diode . Thank you...Leave a comment:

Ok so for start 3v and with amp? I have thermal camera also, to see if any component getting hot(it could be a short right)...Last edited by labello; 02-16-2025, 01:22 PM.Leave a comment:

Hi do you mean right here injection 3v right here, and measured on the t-con 3v test point ? Thanks...Leave a comment:

Hi i just finished to look at t-con board it seems that most capacitor are shorted. I put one leg on the ground and meter gives me sound on bot side.. Maybe is better to find another one .....Leave a comment:

Hi if you talk about those around here i already test it there are good . Thanks...Leave a comment:

Hi man thanks for the reply, yes I know, probably about bad connection in that area the board was in protection modeor something like that., hi made me almost mad,that why i share my experience could be helpful to everyone πThe connection of chip itself was okay, bad connection was around it smd components so I decided to refresh all of them, after that tv is on since yesterday. Have a good weekend...Leave a comment:

Hisense smart tv LTDN50K
Hi guys I want to share my experience with this model, maybe it could be helpful for the community π this tv comes with only led blu/wite blinking all the time, so I check the voltages then i didn't have any standby voltage, so looking on primary side everything was ok(mosfet/ Bridge rectify and so on) same results on the secondary side (both diode rectify was OK) I didn't find any short, looking deeper the ic controller don't ave any vcc power, so I keep going on the components smd everything was OK also strip led was oka,but I hear something (like pulse and I was right blinking and pulse... -
It's the original one, wattage? I don't know how to test wattage. Thanks...Last edited by labello; 02-14-2025, 04:52 AM.Leave a comment:

Hi thanks, so in my case there's too much current across it right, I already changed it but no luck...Leave a comment:

You mean datasheet of the board? I didn't find it π...Leave a comment:

Hi thanks a lot for the reply, the voltage is about 8 voltage. The datasheet don't tells me anything about voltage only the ohms...Leave a comment:

Hi i already changed the pico capacitor, I changed all of them. But stil it doesn't work that resistor still getting HOT as you can see on the picture . Honestly guys I don't know what I should do. π thanks to all...Leave a comment:
