Question about Televison & Video
I have LG 37LH4000. When TV set is cold, only top 2cm of screen works properly and on the other part are vertical lines that refreshes every few minutes. When TV set becomes warmer picture refreshes more often and after 20 min TV set works OK. Could It be a problem with T-CON?

Yes your inverter is bad, I have the same problem my set is about 1 and 1/4 years old. Because Olevia makes a terrible product there inverters are attached directly on to the panel, which means they will only sell the inverter along with the panel i.e $700+ to replace + $100 dollars labor if u don't know how to fix it ur self. I am currently searching to find the manufacture that makes the inverters because olevia will not disclose that information. I believe it is darfon, if so the inverter should cost about $150-200 depending. If you dont believe you can fix it ur self ur best bet is try and sell the set for scrap take ur $100 or so dollar and buy a quality product! Oh and dont call there support they will tell 10 different things before u find out this long for seen truth!

To answer your question;
You`d be looking at a t-con problem.
Buffer/driver boards upper and lower are used in plasma tv`s
Hope this help Good luck

Can you please tell me if you also get lines on the screen with the old old T-CON board also?
Are they solid color lines?
