I turn my tv on the picture and sound all work and after about 20min the picture goes to a black screen and I still have my sound. I turned the tv off wait about 5 min turn it back on the picture come on...


If you have electronics experience - check the power supply and make sure you are getting the correct voltage to your inverter boards and main av board - also do you see any movement on the screen take a flashlight and shine on the screen - if you can see a dark image on the screen check inverter boards and power first.

thanks,

michael

After about 5 min. it tells me digital signal lost and goes black screen.Waited,but re booting only way to get picture back.Then 5 min later black screen again..over and over.


Could be in your computer power settings make sure that you do not have the monitor set to turn off after 5 minutes. Go to the control panel and select power options and check this out. I set mine to all never. Unless it is a lap top computer. If this is not the case most likely it could be a lose connection to the cable to the video card or most likely it is a video card going bad. The only way to fix this is to get another card and to test your monitor plug it into another computer and see if it powers off from another computer.

Picture goes black mins after watching


Bad flyback transformer. It has a short in the winding making the Horizontal output transistor heat up so when its too hot the set goes into protection.

Tv goes fuzzy and when turned of on stand by for 5 mins its ok


This is called image retention where the screen is not dissapating the last picture information quickly enough. This can be cured either by adjusting the settings on the Y-Sustain board or a software upgrade can fix the problem. Either way I suggest you contact an LG dealer to arrange an engineer to do this.
