I would first start with checking the power capacitors. Check for any that have bulged tops.

that is deafinatly a fault. take it back to the store asap if you can. what the tv needs to be fixed is first replace the main and power board and if problem persist the lcd panel will need to be replaced.

SOURCE: Lg 42 picture turns off after a few minutes

Since the sound remains, the power suply board is probably OK. There is a circuit called the "inverter" circuit that powers the backlight of the panel that could be defective. It is possible for the panel to be defective, but that is not common. If you can update this with the model number, I will locate the inverter board part number and cost. That is the most common failure part. Also, if this set is still under warranty (less than a year old), request warranty repair.

Thanks.

SOURCE: My magnavox 42mf438b lcd tv will be fine for about

that set is highly rated by users .. it first came out in early 2009 (i think) so you might check to see if any warranty remains ... the display is illuminated by several lamps .. each lamp has its own high voltage inverter .. all the innverters are powered by an output of the low voltage power supply (often 18 volts)... i would suspect a problem with that low voltage power supply.. either a bad capacitor or a thermal issue .. .. ..

I have a 2 year old LG LCD TV (model 42LG60) and I am having problems with the screen. I turn it on and everything is fine for a few minutes and then the screen goes to red or green lines that are fuzzy....


Not really a solution, sorry, but I've got the very same problem. I haven't noticed the time before tv faults, but nontheless, it greenscreens or like in your case, redscreens as well. I've been told to open the back, which I did to check the status of the capicitors, which I've done. But, the capacitors "seem" fine. No bulging or popped tops. So, I'm at a stand still...not sure what to do at this point. If someone gives you solution, I sure would appreciate your forwarding it on to me. Thanks. Robert

I have a 42 "


Do you have an HD ready cable/satellite box? It sounds like your tv is displaying your games in a resolution lower than what it can handle.

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;

LG 42 LCD no sound or picture


Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.

LG 42 LCD no sound or picture


This is probably bad capacitors on the power supply board. My LG 42LB1DR has a known problem with this and I replaced the four bac capacitors myself and saved 5-6 hundered dollars that I was also told that it would cost to fix. I fixed for under 10 dollars and about 20 minutes. LG knows about it but they dont really want to admit it. My TV was only 26 months old when this happened. The four capacitors are made by Samxon and are 2200uf @ 10v. They are junk so even if you have the entire board replaced for say $200 its just going to happen again. They need to be replaced with a different brand.
