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.

It's the seller not the manufacturer you should be on to, arguing a TV should last longer than a couple of years.
I suspect it is a BGA or Processor issue on the mainboard.

Luckily I have a mobile with IR. I got the service remote and done a in stop reset but no joy, still the same..

LVDS not easily got damage unless they broken while wrong reseating them . this you can approve it with good loop to check the end silver pins if any short or Brocken.

according to last photo you have issue on MB much its like reflow issue on IC100 or Picture processor in case the LVDS are good and there no damage as i mentioned above

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.

It's not the LVDS cable you want, it's the flat ribbon cables that go from the Tcon to the panel boards.
Swap left for right.

See pic for attention,

Def seems to be hardware issue...

with all LG TV which working but had issue, the first things we do reset it with IN_STOP command which it will roll back all drivers. reset the TV via normal setting menu its just clear profile of setting. so start with IN_STOP

Possibly tab bond issue.

Swap the 2 flat cables going from the Tcon to panel over & see if it follows.

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 issue...

Can try going to: picture settings-picture mode/game settings-scroll down to picture options-turn off all those settings/filters, see if that works.

Not sure but tv might be in demo mode, try engine button or some settings button on remote change from demo mode, hit menu for exit.

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 off overnight but still the same this morning...

Could this possibly be a LVDS cable or mainboard issue. If its the screen I presume i may as well dump the tv.

This thread shows similar issues although not identical. Ive found a LVDS cable which is only £8. Can anyone provide a link to a mainboard, not sure the cost of those. The fact that tv is perfect one half and terrible on exactly leads me to believe its maybe not the screen but in fact something smaller...

Im not too bad with electronics, never dismantled a tv like this before, is there a repair guide anywhere...
