Re: Not a repair, only a purchase advice ask for
Some incomplete info I know of LG TVs.
Bag BGA or processor:
LG series from 2009
LD some models
LV
LM
UF higher end models
Horrible panel:
F
J
H
Bad Backlights:
F
J
H
The whole F, J and H series are a fiasco, backlight that turns blue over time, and panel dies like flies, develops horizontal lines or flickering.
Seems that from UM series forward LGs have been solid, at least compared to Samsung, their NU series have terrible backlights. RU, TU and expensive QLEDs have been having panel problems. I haven't seen any LG UM models or newer with any fault for sale around here.
Easy to figure out when you search the motherboard for a select model and check the price, usually if it has bad BGA there will be listings offering to "repair" the board, and a working one will cost at least 70% of what the TV is worth. -

Re: Not a repair, only a purchase advice ask for
being sold new?
LB 2014 < backlight problems
UJ 2015
UH 2016
UJ 2017
UK 2018
UM 2019
UN 2020
UP 2021, being produced and sold for now.
For Nanocell I'll use a single model as example:
SJ8500 2017
SK8000 2018
SM8600 2019
NANO85 2020 - NANO86 in some countries
NANO85 2021
The "U" is for ultra HD (4k), for 1080p/768p LG uses "L" prefix, like LF or LJ
Bottom tier LED TVs have reached stagnation, there's nothing new since 2017, same peak brightness, panel types vary from manufacturer, lg 55 inch is IPS or ADS, they're similar, some 60 inch models uses VA.
Even high tier, most of them are 4k 120Hz, the only difference between them is having a higher peak brightness with mini-led or 8k panel, which has no use right now.Last edited by Biruslapio; 04-13-2022, 04:52 PM.Comment

Hi all,
I've had trouble with the power on this device since I got it. It always shut down with no warning and would often fail to power up. Dell's advice has been to disconnect the power and battery, wait, then reconnect and boot. Letting the battery run down completely also helped. I had them come out at one point and they said they replaced the board. This helped for a while but then it just stopped powering on. At this point it's well out of warranty. I missed the chance to get them to come out again because life. Current situation is it shows zero signs of life with both barrel... -

Problem: I need to purchase a mosfet chip from board 820-02100 M1 Pro, that is supposed to be Q5820 but according to Digikey, the schematic diagram I sent them, neither are relevant to the actual mosfet specification I sent them. I just basically need to find this mosfet to purchase, I cannot find it anywhere and am hoping someone could point me in the right direction without have to purchase this entire allusive board. Already checked with Digikey, Mouser, Aliexpress, eBay. Any suggestions?
Mosfet specs are as follows:

I want to fix Video door phone which works its doorbell but it is not able to display any screen.
So I disassembled its plastic case and I detached FPC film cable from LCD display in order to inspect LCD display's PCB
I measured ESR resistance of all smd capacitor on this PCB and I noticed that there is some SMD capacitor which has high ESR value(48ohm 50V 0.47uf,15 and 28 ohm 50v 3.3uf,10 and 8 ohm 35v 10uf)
I desoldered this 5 suspicious SMD capacitor like below screenshot.

Hi, Im looking to replace some EMP21N03 mosfets on an Alienware motherboard, but I'm having trouble finding a legit supplier. The ones that are available from China have pictures with the engraved logo looking very scratchy and sketchy. Nobody in the US sells them. I'm trying to find a compatible mosfet, but I'm not well versed enough to be confident im making the right choice. Does anyone have a suggestion or advice that could help me find the right mosfet? Thanks!

Hi all,
Recently installed a new motherboard but during the process I seemed to have damaged my Gigabyte Eagle 3060 Ti card.
My motherboard ROG STRIX B550-A is detecting an issue with the VGA (light ON)
I have attached 2 photo's of my GPU board, one above and the other is what I believe to be the 5V - as you can see, this has visual damage so looks suspicious to me.
If I replace this part what are the odds this will resolve the issue? - any additional information on where to source the parts would be much apricated too!
