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...

Re: Repair LG 60UF770V

Re: Repair LG 60UF770V
Not sure what you mean to rework IC under white heat sink. Here is a picture. Where should I heat it, I've got a hot air gun on my aoyue solder Station.
I've spotted a few solder points that look like they need touching uo...Leave a comment:

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...Leave a comment:

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.Leave a comment:

Re: Repair LG 60UF770V
There isn't a main board available anywhere. Lg quoted me 400 quid can you believe
I've got a decent soldering station with hot air gun. I've used the hot air to solder smd leds but never rework components.
What temp should I be hitting it with
Also my TV doesn't turn on at all ow, standby just blinks a couple of times. I can get a power board for 20 quidLeave a comment:

Re: Repair LG 60UF770V
Is it worth leaving in to a TV repair shop. If it is the main board will they be able to repair it without replacingLeave a comment:

Re: Repair LG 60UF770V
LG told me to ring Very. Very told me to ring LG. Both not interested. Complained as much as I could. Purchase price was £1099. Tv 2.5 years old. 1 year warranty.
LG said new main board £400.
I’ve got this lvds cable through, Is it worth replacing?Leave a comment:

Re: Repair LG 60UF770V
Problem is worse now, tv not coming on at all. There is power, standby light flashes red three times but nothing displayed on screen.
Does this point to the main board, can't seem to get one on eBay or anywhere for that matter.
Thought LG may have got back to me, wonder what they might do for me if anything.Leave a comment:

Re: Repair LG 60UF770V
Luckily I have a mobile with IR. I got the service remote and done a in stop reset but no joy, still the same.
I done the test screens, the colours only show up on the good half, does this mean anything
I have already ordered a lvds cable as it was only £8. Since removing TV from wall is a pain I will do the cable swap test when new cable arrives
Do I need to swap lvds cables at both ends or just one end....Leave a comment:

Re: Repair LG 60UF770V
TV needs to be in store mode to set demo mode. Buts ive reset it anyway and can confirm its def in home mode. Gaming settings hasn't made any difference. I don't use that mode anyway. Turned off all picture settings in normal mode...no difference
Ive opened up the tv and taken some pictures so I know if i do buy some parts they will be correct. I plugged out cables and reseated lvds cables but hasn't helped.
There are two lvds cables, is it possible one cable has affect one side of tv...
Def seems to be hardware issu...Last edited by aidy55; 07-21-2019, 06:53 AM.Leave a comment:

Repair LG 60UF770V
Hi folks, I bought this tv in 2016 from Very. I don't think it came with a 5 year warranty but Ive sent a repair request to LG to see what they say. Last few expensive AV items have been bought from richer sounds as they seem to do 6 year warranty on everything.
Anywhoo, this tv has been great past few years and i literally was watching a netflix programme last night, paused it to answer front door, came back and tv was like this.
It seems to affect only the right half of the tv. The menu displays on the left hand side so I was able to reset tv but no joy. Left it... -
