Question about Televison & Video
We are getting horizontal lines across the screen about 4" apart plus on the right hand side of the screen we are getting the picture repeating itself (ie when the weather forecast comes on, the difference place names we can see about four or five of them underneath each other). An engineer has told me (over the phone that he thinks it's an inverter board, but after reading some of the things re inverter boards I don't know if it is or not). The tv is a Samsung LCD - model LE40F86BDX/XEU. We have had the tv for six years this October and until recently we had no problem whatsoever.

Horizontal lines are relatively rare problem in LCD TVs.
The likely problematic areas are:
1) The LCD itself (the micro ICs embedded into the LCD panel structure); that doesn't sound likely based on what you say, but it's not completely impossible. The bad news is it's mostly uncurable.
2) The power board A-1511-322-D G5
Power boards may sometimes cause problems with display, although rarely causing horizontal lines.
I wouldn't start looking here either, but it is certainly a problem to consider.
3) Main board 1-876-561-13 R1506072C
Slightly more possible and yet not quite likely. A high operating temperature and bad SMD soldering process may cause some soldering contacts on the main board to behave differently when the board is cold versus when it heats up. It is very common and may have all kinds of different effects on the TV and the screen.
One way to check for that is with a regular dryer..the process is explained in many other solutions at fixya and around the net, so I wouldn't repeat it here...but it takes time and patience.
4) The most likely place to start with is the T-Con / LCD controller
I'd first replace that and see if the problem goes away.
5) There's a very minor chance that the LVDS cable that connects the main board with the T-Con does not make good contact initially and changes that as a result of getting hot. It's easy to just touch and move it lightly when the TV is still cold to see if it has an effect on the picture.
Sorry I couldn't just nail it for you, but that's the nature of the repair businss :-)

SOURCE: I have a Flat screen
Are the lines all the way across the screen? or just a few? Solid black - or trannslucent?
Horizontal drive has either data, voltage, or control problem from the pixel registry circuit......get it serviced before the problem spreads causing further damage.
However, in all likelyhood, the panel itself is bad. The Bravia line has had a bad rap about the faulty displays, and at $1800 replacement (plus labor) - it may be time to call SONY direct to complain!
