Main board substitute for LG

[mannuoye]

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.

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?

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.

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.

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.

For half the price you could get your original board fixed

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

Re: Main board substitute for LG

did you ever try that LV5700 board? Is 55LV5700 a model sold here?

Re: Main board substitute for LG

No I didnt tried LV5700 because the one I used was specifically made for my TV
