I've been getting intermittent pixels on all channels on this TV and now when it's turned on the left half of the screen is totally messed up but after a while it goes away (for now). This TV is almost three years old. It's getting worse daily and I'd sure appreciate any help greatly!
I just fixed this problem on my friend's a couple of days ago. It is indeed the tcon board. It does not need to be replaced though! I just took it apart, cleaned the grounding connections with isoprol alcohol, and double checked all connectors. Turned it on and it worked great! I hope this helps yours and anybody else's problem! A lot cheaper than sending it in for repair. Don't try this if you're inexperienced at fixing electronics though. There are some high voltages built up in the power supply.
The T'Con board might be faulty. You have to check all the connection strip wires goes to in and out for any loose. T'Con [Timing Control Board] board is one which controls the pixels on the LCD screen.
Testimonial: "Thanks so much for all your help. You've been awesome!"
Thanks for the help... Would this possibly explain why the left side of the TV keeps looking scrambled now? It's intermittent at this point but sometimes completely wipes out the left half of the screen and then after a while it seems okay again once the set has been on for a while. I'd really appreciate any added advice!
It will be best to get the set repaired by any well experienced service technician. Because, the strip wires that goes in and out to the board are of carbon conductive types, and can be easly damaged if handled carelessley. More over there is a lock for each end of these wires, that only an experienced one can take it out and reinsert in to safely. The fault is loose contact itself.

SOURCE: I have an LG 42" LCD tv with blurred image on half the screen
lg 42 in lcd tv power button blinks nine times before staying on and has sound but no picture
SOURCE: lost half of picture
This can be on the matrix drive board, or the display assembly itself. It is possible to also have a defect in the address decoding area that will cause this.
The procedure is to swap out the suspect boards to determine where the fault is, leave the working boards in the set, and then follow up any necessary calibrations that are necessary.

This issue is a common,
but hardly talked about from LG. Your tv is probably 1 or 2 months out of
warranty, and now you're hearing a series of clicks. ... If you have the
courage to open the back cover of your tv, and you do "NOT" see any
bad (bulging ) capacitors on the power supply, then it could be the voltage
regulator. After weeks of fighting
with LG to replace my tv, i decided to fix it myself. i'm proud to announce
that my 50PK540 is now working. want proof? Take a look at the video i

OMG i'm having the exact same problem with my LG 42" LCD tv that is 3 years old. I was told that the LCD was bad and that it would cost me $624 to fix. I don't know what to do with this tv.
