SOURCE: looking for screen replacement for LG LCD model

You could try disassembling it, because in most cases on lcds there is the very delicate actual panel, and then a thin piece of protective plastic. If there is, you can simply replace that. It all depends on whether the lcd itself is damaged.


Without more information, it's difficult to tell how hard it'll be to do. It can also be quite expensive (usually around the original cost of the TV for a new replacement screen). If you have a LCD projector set, that too can be quite expensive unless you're able to obtain a rebuilt unit somewhere.

I would recommend selling the parts on ebay.

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 ) 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.

No power on LG 42LK450 LCD TV(Remote or manual)

Does the power LED at its front panel light up? If so, the fault should be with digital main board. If it blinks, count the number of blinks that occurs at one time switch on and go to this link for details. It has details about blinking codes to many brand TVs. Pull up older posts there by its left side bar. You can get an idea about the faulty stage inside your TV. If you want any more assistance, be free to comment by Fixya

LG 42LK450 flat screen.I tried auto tuning but didn't pickup channel 31. I tried manual tuning with no result. The old style TV I had prior to this could pick up channel 31 so it isn't a reception...

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.
