My LG TV
switch on no picture but short period of sound then nothing

TV was working fine, moved to new home and the problem began. Picture rolls to the right, picture is fuzzy and will clear up somewhat at times. The picture will stop rolling at times also,but may be a half and half screen. Sound is fine, can you help me with this problem please.

To verify that the tuner is the problem, move the cable from the second to the first. If you don't get a signal, the tuner is bad. The main tuner is part number 859843000 and is available for $47.38 from tritronicsinc.com

No,not repairable,because the front screen panel are 90% of the tv,sorry ur tv now,it only can be salvage for electronic boards for parts,that it.The tv screen panels are only can be purcharse from the tvs corporation themselves.They'll charge u the screen panel the same priced as new tv.Because the tv screen panels are in limited production and 90% improtant to the tv,that why.
