Question about LG 42 42LK450 42 LCD TV
Prior going to black had vertical lines across total screen - have replaced the T-Con board as I thought the vertical lines were caused by that - no success, than the backlight inverter board. Have checked the capacitors on the pwoer board and they all look fine. Have also put in the old t-con with the new inverter board.
Sorry but you have a bad panel. Repair cost is prohibitive. The T-con was a good choice, but is the last step to the panel.

Tv has a short on the vertical scan board, the board needs to be replaced. The board cost around $89 bucks its a pretty easy fix one you could do yourself....

As soon as you take the back off the set, the t-con board is located at the top middle of the set under some shielding.

If your trying to receive over the air make sure the TV is not set to a Cable mode, if your on Cable your new TV is most likely a ATSC tuner (digital) and the cable company can map channels any way they want. If your old TV had the older style cable tuner, the lineup will be different.
HDTV has level thresholds, if the signal is weak you wont see anything, but the old TV would.
Without knowing much about where or what sort of TV your using, these are my best ideas.
