You need to monitor your standby voltages first, to see how stable they are 5v-3.4v-12v. If they are stable then locate the ON command pin going to the inverter board and see if it is going High then Low. If it is then replace the main board.

Inside your LG there is a component call backlight inverter that is was cause of the loose of tone. Normally the part is located on the left side of the screen. You can call LG and they can give you the part number average cost is about $45 to $75.00 very easy to install.

Green discoloration is bothering the whole screen.


Check the pins at both ends of the cable, also try it on another PC to make sure it is not the PC video card problem.

I am starting to get a discoloration in the bottom left side of my screen. It is slowly making it's way up to the middle of the screen.


If it is a tube type TV, probably needs degaussing. The screen within the crt becomes magnetized or external magnets from speakers are causing a problem. Sometimes changing the direction or position the tv faces causes degauss problems. If moving nearby speakers changes the discoloration, then speakers are too close or TV needs degaussing. Some high-end Asian tvs have E-W adjustment in users menu to correct this problem.

If it is RPTV 3 tube crt TV, maybe a convergence problem.

If it is DLP or LCD rear projection, probably optical engine failure.

What model is TV. Is picture normal in BW with color turned off?

I loose my picture but i still get sound


Just try to reset so picture will come again, some LCD TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the LCD TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the LCD TV power button for five seconds.
4. Plug the LCD TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the LCD TV is responding again.
6. Turn off the LCD TV and reconnect the devices.
7. Turn on the LCD TV.

Hope it may help you;

Got a 51" LG HD


The LCD panel can not be fixed, only replaced. Without the model number, I can not give you a cost, but expect the cost to exceed 1/2 of the original purchase price. Post hte model number and I'll get you the part number and cost.
