Question about LG 42LG30 42 in. LCD HDTV

1 Answer

I have a LG 42lh30 that gets a distinct vertical bar, about six inches from the left hand edge of the screen. Occasionally the area between the vertical bar and the edge will be filled with small horizontal bars that flash. Sometimes after an hour or so, the bar and discoloration on that side goes away and sometimes it doesn't... sometimes turning the tv and jiggling the wires on the Aux. AV port will make the line go away, sometimes it doesn't. Is it fixable?

Hello
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.

LG 42LH30. About six inches of screen on left side goes white. If pinch outer edges make it go away but seems to come right back.? Suggestions. ?


This is most likely the panel itself, but could possibly be the wiring. Check the wiring on the panel to be sure it is not corroded, loose or broken. if it is any of the fore mentioned repair or replace the cable.
If it is the panel & under warranty, contact Manufacturer. if it is panel & out of warranty, replace unit as panel replacement is not cost effective even if the panel is available.

The color red and especially red colored lines or a pinkish hue are indicative of an impending screen failure. The only other possibility is that the data cable on the left backside of the lcd panel may be loose at the socket or on the motherboard. 9 times out of 10 though, it is the lcd panel that it failing.

Red line down right and left side of 42" LG plasma.


Hello; I am John at J D Electronics in Poland, Maine. I have an LG TV that was donated to me. It is a plasma model DU-42PX12X. It had 1 inch wide red and green vertical bar on the right and a blue and yellow on the left. These bars appeared intermittently. pressing on the control board would make the bars go away. I have read many blogs on this problem and they all say to replace the control board located under that huge A / V input board ( held in by 4 screws on the large aluminum frame). The original part is # 6871QCH038A The replacement ends with a C instead of an A Aprox 90 to 135 dollars. This board is used on many different LG and Zenith models and is a HIGH failure rate part. I like to know WHY parts/boards fail and I found out why this board fails. There is a large square IC in middle of the board aprx 1 1/8 inch square. This type of IC is called BGA or Ball Grid Array. The solder connections cannot be seen , since they are under the IC . This IC was not properly soldered at the factory and that is why hundreds of these sets failed. I used my hot air soldering station on it's highest setting to heat up this IC . The IC must be directly heated from the top and some heat on the bottom of the PC Board. Liquid flux should applied to the 4 side edges of the IC prior to heating. The bars are now gone! To get to this board, remove all perimeter screws and all middle screws of the back cover. The A V board will hinge back to expose the control board if you unplug the cables to the side inputs and the one to the button board. The set will still run face down on a table with something to prop up the bottom screen so you can watch the bars. If the set was run for a long time with the bars, there will be some darkening where the bars have " burned" the screen. This is perminent, but usually acceptable.
