Re: Repair LG 60UF770V
Will try all these tips.
I think I will replace power board as well since I can get one for £20.
Maybe it will allow the tv to turn on again
Is it possible to test mainboard, is there schematics available to check readings with multimeterLast edited by aidy55; 08-02-2019, 11:34 PM.

Re: Repair LG 60UF770V
I've replaced the power board, no difference. Replaced one of the lvds cables, they are not the same, they are different sizes so could only try on. But I don't think its that anyway. Going to return these parts.
I can get a t con board on ebay but not sure what that could do
A computer repair shop nearby does bga rework, might try them.
But the TV is not booting up at all. When you press the power button the TV does light up but just black screen but it is even back-light if you know what I mean, so it couldn't be display
Still can't find anything solid on why standby light blinks twice

Re: Repair LG 60UF770V
You mean this chip here. Yea looks difficult. I can see what I can do with my heat gun.
Ready to give up on this TV. Its up in the attic now out of the way, will have to make do with a 42 inch on the wall.
Maybe will find someone who has smashed screen, spares and repair.
Does anyone know of any centres that may deal with large number of broken TV. Basically a scrappy for tvs lol

Good luck with finding one though, BGA failure on the LGs is common so they are rare. You might get lucky on ebay but most people seem to ask silly money for broken screen TVs, although you do occasionally find them cheap.
You ideally need more than a hot air station to effectively reflow the solder. The heat has to be even and you don't want just the processor area heating up, the whole board should be around 150c to avoid thermal stress before reworking it.

Might find a replacement board on that page but who knows if it will have the same problem in the near future: https://www.ebay.com/sch/i.html?_fro...&_odkw=fire+tv
