LG 49uf695v vertical coloured lines

[pni]

Hi guys…I need your help. My cousin ask me to fix her tv. The tv when I went to pick up showed 3 horizontal black line. So I know it was a bad panel issue but I could try to fix with the tape method so I said her I could fix easy. When I come back to home, I turned on the tv and now the tv show vertical line colored….and the problem is that I unplug the ldvs cable, first the right side then the left side I still have the lines. The lines never disappear. When the right side is plug in I don’t have nothing on the screen only this vertical lines, when the right side is unplugged I have picture on half left screen but always with the vertical line….did I finish to break the panel when I pick up it from her house? Can I fix it?

It's not so important in a closet or not, if is at open air, more or less, it damages itself, modern tv sets are very fragile, there is no efficent cure as i have fully tested until now, you can only try heating with hair dryer the panel fpc (flex tabs) until some oxy goes away.. i do not see horizontal lines..

dont use hair dryer or any source of hot air.. its wrong from some one dont know and dont have the right tool.... buy T silicon Iron for COF and apply to the COF near to line area... this could help some time but not always as need to renew the COF pasta.

why you asked this and my warning didn't took it,, now you pushed air between COF and Glass , nothings you can, only COF vacuum Stamp machine can renew the defect COF soldering... search at your country service they have the vacuum stamp machine.

The T shaped iron tip does not work, i own this and i already used, the faulty connection can be between the chip and the flexi support, they are bga or qfn chips, if a soldering is poor there, much better to apply heat directly with normal cone iron tip, rapidly on the amber side, with a shim in the other side, otherwise the cof breaks, the T does not apply correct heat
