Wide screen viewing

I have a LG model # 42PX12X and since I moved I no longer have wide screen viewing. Everyone says "thats just how they shoot the programing" if thats so why did I buy a wide screen TV?

Several possibilities but most common seems to be power supply defect or poor connection. Check these resources. Note that other Youtubes that may address the problem are also accessible from the youtube link.

HD channels look terrible


You may not have the resolution set to hd even though you are on the channel. Confirm that you are using hd cable and your set is displaying 720p or greater. This will sometimes pop up on the screen when you tune to a hd channel. it sounds like you are on 480 i or p. good luck

Isee half the screen the other half is black and colour vertical lines.(42) Can that be fixed? How much? This is asecond time that happens.The tv is lg model du-42px12x. Tell me of is worth to fixed or not


FIrst of all this is a plasma set and thus does not have a "convergence" board. This could be as simple as a bad cable connection inside the set or a failed supply for one half of the plasma panel. If the unit is no longer under warranty. try removing the back and reseating all of the cables and connectors. Since the signal levels are extremely small inside, it doesn't take much to cause a problem.

Update this with your results and we'll continue as dictated by the results.

Issue with LG Plasma tv model # DU-42PX12X


Another "same probelm"

My set has encountered this magical 50/50 split screen and it seems to be quite a problem since I am not the only one researching this issue. LG was of no use because of course it is just out of warranty. Any solutions on fixing this or am I out of money in buying a new plasma?

Lost video on LG plasma big screen model DU-42PX12X


LG Plasmas and all plasmas have problems with the sustain boards. You can replace them with just a screw driver to remove back and boards.  Try tritronicsinc.com and andrewselectronics.com and search for Y and Z Sus boards.
They are not cheap and you may want to call a qualified servicer or deal with return cost if they don't work

LG DU-42PX12X Verticle lines of various colors, and widths throughout the screen.


Check within you area for a reliable LG repair center. To fix the problem of the blue, red or green vertical line you just need to replace the control board PN 6871QCH038C. The part cost about $150.00 and a honest repair center should not beat you up to bad on the labor. Good luck and Good viewing.
