No, it is an LCD Television, so a lot better.

No picture on LG 42LK450-UB TV Red standby light at plug in and blue light on power. Removed cover and no backlights lit Is the board that drives the backlights bad and is board part of the PS board.


Hey Marc,
You question is a little open..... there is more info needed to help narrow down the problem. If it is a backlight issue you should still get sound out of it and you should be able to take a flashlight and shine it on the screen and start to see a picture( note this part takes a little patience and staring, it will be hard to see it but you will if it is there). The backlight driver board is a separate board ( here it is at shopjimmy http://www.shopjimmy.com/auo-19-42t14-001-backlight-inverter.htm ) You could also have a bad main board: example- no back light, no pic, no sound, but it seems to turn on and off. In that example the firmware on the main board became corrupted due to a failing board, so check those places above and feel free to order that backlight board.

LG LCD TV 42LK450 - Sound but screen is black..


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.
