Question about LG 42LG30 42 in. LCD HDTV
The fault is due to its horizontal sync-seperator and horizontal phase detector section, and it is not user servicable. If you want to do it by yoursef, you must have thorugh knoledge in both digital and analogue electroncis, and a high quality digital multimeter to access these sections. A multimeter of the above said type will cost a lot, that it will be a great loos for you to muy such one, more that its service cost. Moreover, you must have a good concept of solering, a sodering iron with ceramic tip, a very steady and stable hand, more patience and concentration, A magnifying glass may also needed.
In my opinion, it will be best for you to get it repaired by a well experienced service technican, who have most modern testing equipments. Otherwise, things will go worse than present as it is. OK.
