Morning I don't understand this (a resistor on 3.3v) you meant should I mesure with a resistance mode on 3.3v or reading or what voltage i have on those resistance . Then with one, of reg 12v i should put the car lamp it's 24v car lamp will be okay or i need the 12v Thanks

For the 3,3v i would load about 0,5A with a power resistor about 6-7ohm 2W, for the 12v you need 12v lampComment

You have, as i explained, load the board with = connect that resistor on output of the 3,3v standby, and the light bulb to the 12v output, then check if the first heat up and the tension, and if the bulb light up bright and the tension also..Comment

At the ground output (GND)Comment

what sorry..... if you want to continue with this wrong experiment ob to you i just waned you... enjoy toastingComment

OK you made a mistake, you connected TCON 12v output with 3,3v output with yellow wire, but since tcon output is so disabled you would have had no damages... so move the Yellow wire to the end of connector,.according to the printed scheme near there.. 12v 0,7A is not so bad as an experiment, so proceed..
when you finished, leave the set as is, there is the second part.. where you add another jumper BL_ON - 3,3v , connect the led lamps and check if also leds turns on....Last edited by Davi.p; 11-19-2024, 01:02 PM.Comment

Ok guys I stopped myself because the tv is not mine, so I'll put the main bach on the tv and i have 3.3 v the tv turn it on but restart it and then error seven again. How many voltage i should have on the output led? ThanksLast edited by labello; 11-19-2024, 01:04 PM.Comment

Why did you short-circuit stby 3.3v with a 7.5 Ohm resistor to GND? You will kill the power supply completely.Comment

Don't listen to Diah, the test is 100% good, R 6ohm as a load is good, V/R=I=3,3v/6ohm=0,55A
Pr=3,3*0,55=1,6WLast edited by Davi.p; 11-19-2024, 01:16 PM.Comment

Ok is better to close.. I'll speak to the owner to buying another board and that's will solve the problem, because the tv still have same issue. I don't think about leds because they are new.So I ask again what voltage I should have on the output led...? Thank you!Last edited by labello; 11-19-2024, 01:33 PM.Comment

hello everyone I am looking for a solution for my tv, I think corruption of the eemc,
the TV starts, LG logo, then nothing (rear backlight)
no reaction to rear command or infrared
the usb procedure that I tried on the LG site is a procedure with the screen and the remote control so I can't.
I have a chance with a usb procedure or other if you have .bin
if any people have this main board
Sony LG 60la620s EAX64797004 (1.1)
thank you... -
Hello,
Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.
So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.
I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,... -
I'm looking at the transmitter from these wireless headphones because the range is too short. One of the LEDs failed many years ago (nine years ago - I found pictures that I took then) and was simply bypassed to make them work again, but it seems like the range has been degrading since then. They're near-IR LEDs (I can see them dimly lit red, so they aren't the standard 940nm), and I haven't been able to find the actual wavelength. Does anyone here happen to know what replacement LEDs I should use? Maybe I can adjust the transmitter was well while I'm in there, or there's another fault. I should... -
Hi all,
Because of two bright spots and a couple of dark spots I decided to replace the backlights in my Samsung UE48JU7000. See attached photos:
I thought all went well, but after full assembly and testing it out it turns out not all is fine. The backlights are completely fine but I have some weird issues on the right half of the screen. Since I didn't really touch the T-CON board (apart from taking out the ribbons of the display and reconnecting them on assembly) it would be weird that the issue is with the T-CON board... But based on the behavior of the service... -
Hi, I'm hoping someone can help me with this issue before I give up on this TV.
In short, I replaced the T-CON board due to an error code indicating that was the problem, after which it flashed a green and orange LED meaning software update required. I cannot get the tv to do the required update via USB, so I am stuck.
Here is a rundown of the symptoms and the steps I have taken to troubleshoot:
I inherited the TV with the symptom that it would turn on, then turn off after 5-10 seconds and a red LED flashed 4 or 5 times. Sometimes it would be 4, sometimes...
