I have a faulty main board of LG 55LW6500 TV and LG stopped making them any more and I am unable to buy replacement anywhere. I do have access to LG 55LV5700 TV's main board which visually looks exact copy. Can I use it?

Re: Main board substitute for LG
hi there the simple answer to this question is NO
as the T-Con will be different to the one that matched your original mainboard.Samsung UE46D6530
Samsung BD-F7500

Re: Main board substitute for LG
Thanks for replying, but both main boards output double LVDS (one 51pin and one 41pin) which is similar too. Do you still think there will be a different T con?Comment

Re: Main board substitute for LG
For anyone who gets into the situation like me, I have found the substitute for the original mainboard.
LG makes a repair package for LG 55LW6500 TVs which includes a mainboard, a small remote PCB, a magic remote and a regular remote. The part number for this assembly is AGF78482709
I ordered this today and hope to get it in next 7-10 working days.
I will update after installing it.Comment

Re: Main board substitute for LG
Hi I got it from www.statewideapp.com.au in Adelaide Australia. believe it or not it cost me $248 only and It worked!!!!.
One thing I would like to mention is I lost one HDMI port so now I have 3 instead of 4 but that does not matter because I use only one and there is no VGA port in this one as well.Comment

Re: Main board substitute for LG
only 248$? https://www.statewideapp.com.au/lg-package-assy-253711 doesn't really say anything about what you're getting.
Kinda seems really high. Do you know what's included?
Also, I just wanted to add, one time, I had two boards that where supposedly compatible and weren't. They looked identical, came from the same make and model TV, the one replacement I bought worked, just not in this TV. The one difference was some hack someone made a long time ago (maybe the manufacturer, because ShopJimmy _used_ to sell these boards with the same hack). No one could tell me what the hack did.
Anyway, I noticed all the small EEPROMs on the boards and just swapped them around. New board worked like a charm. Keep in mind though, with this television, there where a few extra boards that I don't normally see on TVs, like some sort of daughter board for the CD-ROM drive (a CD-ROM drive), etc.-- Law of Expanding Memory: Applications Will Also Expand Until RAM Is FullComment

Re: Main board substitute for LG
For half the price you could get your original board fixed

Re: Main board substitute for LG
Unfortunately here in Australia its not cheap to get electronics repaired. I tried two recommended repair places and they opened their wide mouths. $66 to get a quote and $180 to put an new board in the TV. Main board charges extra.
All they didn't said to me was to turn around and bend. So I think "only" can go with $248

Hi and thanks in advance for any input you might provide!
I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO
Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this... -
Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.
Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
Power Board Connector that goes to Main board
CN6401
Pin 01 NC
Pin 02 NC
Pin 03 "BL_ON": 0V
Pin 04 "N/C"
Pin 05 "STBY 3.3V": 3.5V
Pin 06 "GND": N/C
Pin 07 "AC_OFF"... -

Issue: No Power, Then Rebooting After Main Board Change
Short answer: replace main board and power board
Technical answer: replace main board and Q306 & Q307 on power board.
Long answer:
TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge.... -
Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
Obviously the same LVDS connector for the screen connection...
