Question about LG 42PX4DV 42 in. EDTV-Ready Plasma Television
My LG 42" has started to display a breakdown of the picture after being on for 5-6hrs in a room temperature of 60-65F and 2-3 hrs at an ambient temperature of 65F and up where there is picture breakthrough behind the main picture,skin tones and scenes with white walls and similar go silvery and if left in that state for a while the screen has a lot of pixellation.If I switch to standby for 10-15 minutes then switch back on the fault has disappeared for a short while(about 1 hr) before starting again The set is less than a year old but the sellers have disappeared and LG don't have the courtesy to reply to my email.
Try putting a fan on the back of the tv to see if it is getting better. If it does then you probally have a board that is overheating. If that is the case then CAREFULLY !!! remove the back and place where you can turn on and safely access the open back NO TOUCHING STUFF !!! Mabey lay it face down on a glass table or lay it on a table with 25% hanging over the edge to see the screen. Then take a COLD blow dryer and blow it on the boards to find out which one makes it get better. If one does then it will probally be your problem board. Make extremely sure that is the one before removing it by blowing from all angles on the boards around it without air hitting the suposed problem board. Then try a little hot air to see if that starts the problem on that board so you can be sure. Of course check the surrounding and offending board several times to be sure before removing.

As you may have guessed by now, the breakdown is likely being caused by a bad connection or ground. May need resoldering unless it is a semiconductor breaking down. If you can find a service center that services LG (low grade) products, I would take it there for repair. You have probably noticed a lot of heat escaping from the top of the unit after it has been on awhile. That is a big problem with plasma TV's as heat is the biggest destroyer of electronic parts that I know of (well after lightening storms). A temporary solution would be to install some fans blowing air up from the bottom back of the unit to allow it to play longer before getting too hot. Or watch less TV
