Re: LG 55LS4500 No Standby light will not power on
There's some on ebay here, I'm not sure which sticker numbers need to be matched up for compatibility. https://www.ebay.com/sch/i.html?_fro...acat=0&_sop=15Quit because THIS SITE LETS A ROGUE MEMBER TYPE ANY GARBAGE HE PLEASES AND THE POWERS THAT BE NEVER DO ANYTHING ABOUT IT SO HE NEVER QUITS.

Re: LG 55LS4500 No Standby light will not power on
okay I don't usually purchase something unless I know what I am buying.
The control board has an orange sticker bottom left, next to mounting screw. It states:
55L84500-UD.AUSWLJR
VER.3.20.12
PM.VER.3.1.2 Y.C hand written 2
How does one go about making sure the control board is a duplicate or a compatible board?
Other places selling a control board for a LG 55LS4500-UD on the internet state:
Part Number: EBT62227807
Identifying Numbers That Appear On This Specific Part: EAX64437505(1.0) / EBR75708201
Works in televisions with SVC code: 55LS4500-UD.AUSWLUR
One other thing, the control board main IC had two dobs of clear translucent silicone securing the black heatsink. Some boards on Ebay have white dobs of silicone have these been repaired?????Last edited by RFITTS46; 07-10-2019, 07:55 AM.Comment

Re: LG 55LS4500 No Standby light will not power on
Ok, looks like you need to match your svc code if yours is 55LS4500-UD.AUSWLUR then those boards should work. I did notice that there's an S in the code where yours is an 8, I see the J and U are different too, I don't know what the difference is if there is any?? I know the boards look the same.Last edited by nomoresonys; 07-10-2019, 09:37 AM.Quit because THIS SITE LETS A ROGUE MEMBER TYPE ANY GARBAGE HE PLEASES AND THE POWERS THAT BE NEVER DO ANYTHING ABOUT IT SO HE NEVER QUITS.

Re: LG 55LS4500 No Standby light will not power on
I guess the easiest way is to call or email shopjimmy or another trusted entity and ask them how to match them up.Last edited by nomoresonys; 07-10-2019, 10:10 AM.Quit because THIS SITE LETS A ROGUE MEMBER TYPE ANY GARBAGE HE PLEASES AND THE POWERS THAT BE NEVER DO ANYTHING ABOUT IT SO HE NEVER QUITS.

Hello everyone,
I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
What I already found is that the 12.8V are not an the connector to the main board connector to the power... -
Hey All,
I have a Sony 65x900f that I purchased cheap because of a no-power issue.
I assumed that because there is no standby light visible, it would be an easy fix - however upon opening up of the unit I can confirm that the 3v3 standby voltage is making it's way from the power supply to the main board. I'm a little confused as to why there is no standby light.
I am firstly wondering if anyone has this model of TV, or has worked on one and can give me some insight. I have tried to find a service manual for this model, to no avail - and would really appreciate... -
Hi everyone,
I'm trying to troubleshoot and repair this old LG OLED curved TV, model 55EG910V.
I did some basic troubleshooting and reviewed most related posts here, but I wasn't able to isolate the issue.
The TV shut itself off during playback and never came back to life - the standby light remains off. My dad claims that it has happened a few times in the past but the issue resolved itself after some time. Not this one.
After checking the basics I did the following:- I measured all voltages and as expected the only active supply is the 3.5V standby. It

TV: Samsung QLED QE65Q7FNAT
PSU: BN4400940A

I got the tv in spring 2024. At that time it started, then ran 60 sec and poweroff. Seemed like reboot issue. I didn't have time and room to check it in summer so I plugged it in and now the standby light is on. I press button on remote, standby light goes off and tries to start?. No picture or backlight on LCD. I thought about removing diodes like in this thread: https://www.badcaps.net/forum/troubl...sung-qled-q60r... -
picked up a tv and when the power is plugged, the standby light flashes real quick then goes off. of 3.3, 12, 24v is all there but i couldnt find any 5v on the back-end board. ON/OFF is low, which it seems is what turns on the backlight so i removed the wire at the back-end board and put a 10k resistor to the 3.3v, which when plugged in brings on the backlight for a split second and also a blue light "LED1" on the inverter board, which goes off after a short time.
am i missing something to bring on the backlight or is the inverter/ccfl gone bad? would that cause the inverter board...12-01-2023, 09:55 PM
