Hi,
This symptom indicated that the T-con board (LCD controller) was already gone bad. The problem is that, this board is not repairable. You have to contact your local LG service center for parts availability. If you can't troubleshoot the unit yourself, I would advice you to send it to them. Ask for an estimate first for parts plus labor to have an idea how much money you are going to spend sending the unit for repair.
Thanks for using Fixya.

    I've had the problem today and just fixed it using the following method.

    Press exit on the remote control. Power off on the remote control. Then power on and select input. Worked for me!

Hello i have a 19 inch LG M197 WDP monitor/tv, when i switch it on the screen is white with a little gray bock that flashes and slowly moves across the top of the screen reading v3.02.0 which i presume is...


I also had an LG M197WDP tv/Monitor with the same problem. It comes straight on when plugged in, but with the blank screen and scrolling version number across the top.
The solution:
1. Use the remote control (check batteries first)
2. Point at the working TV and press either MENU or EXIT
3. Static should be seen on the screen.
4. Switch to standby using the remote, by preesing POWER button.
5. Switch back on using the POWER button.
All should then be working normally

Mines a LG RZ42PX11 it intermittently gets a black vertical line down the middle of the screen.


Hi I have a LG RZ42px11 there are 6 vertical thick black lines running down the middle off the screen, when cold the TV seems OK but if it has been on for around 10mins or on standby the lines stay on screen.

Thanks.
