Half picture on LG LCD TV

I have a LG LCD TV model #42LB5ZDF and late when I turn it on I only get half a picture. One side of the screen comes in clear while the other is pxelated and streaky. Once the tv warms up - anout 20 seconds, the picture returns to normal
Any idea waht could cause this?

You need to replace the inverter board if you can find the spare part. Otherwise you need to replace the whole lcd panel.

Try One of your working TVS and connect it to your cable outlet of the TV that is having problems. If that TV Does not work then there may be a degraded fitting or the Leg coming of the splitter to that outlet could have a Low Signal Problem
Next Take the First TV that was not working properly and put it on the cable outlet of one of the TVs that is working properly and if the TV set works on that Channel then you know it is not your TV that it must be the cable

Only half screen working


LCD sets commonly use inverter boards--two which each drive half the screen for a picture---

Google the model number with "parts" to see a possible list of them--Shop Jimmy is a good source for this type of information.

Half screen is blank 42lg20 or 42lg50 when


This is likely to be the T-con board. If the entire screen glows but you have no picture on the second half of the screen then it is the main board, not the backlight inverter. If the screen is half picture and half gray it is the T-con board.


Replacement of one of the above will fix the issue.


Please rate if this helped :)

Have 42 inch LG flat screen...for about 3 years...


Take the back off with no power connected..You should have 2 invertor pcbs..one on the left and one on the right..well the side of the picture you cant see is the same side of the faulty invertor..replace this and this should solve the problem.it is the cheapest option..if not..im afraid is is a new LCD screen unless you are prepared to take it appart and replace backlight bulbs :)
