Question about LG RU-42PX10 42 in. HD-Ready Plasma Television

1 Answer

LG 42 in goes off and on every 15-20 minutes

The TV goes off and on every 15 or 20 minutes or so. I checked the timer settings on the menu and all are off or as far as I can tell they are. I read on another post about fuses; could that be it. We've had a few storms lately where the power went off, but nothing else seems to have been affected. If it is a fuse, where would it be? It's 2 years old today and of course the warranty was for 1 year. I appreciate any suggestions.

Plasma tv randomly goes black


By the highly technical manner in which you set forth the problem, I can see you are far more electronically savy than am I, BUT just a thought: Is there there any sort of timer setting in the TV menu which may be cutting it on and/or off, and which you have somehow failed to notice? Good luck. . .

Why does my LG TV dim every evening about 7:30 and rebrightens about 30 minutes later?


If the TV is turned on random time before 7:30 and it always dim at 7:30, it either has a timer setting to cause dim (please check the settings from main MENU) or may be related a TV station signal if it happens on a certain TV channel.

My LG Lcd tv takes a minute or so to turn on then sometimes the picture flickers and goes out. The tv is on but no picture or sound. When I try to use the menu button on the tv it doesn't work. Whe


The fact that you have no menu or onscreen display, leads me to believe that it is the main logic board. Either the processor ic or the voltages going to the main board are missing. Check to see if the main board is getting 5v and 3.3v to determine if it is your power supply not supplying the voltages or your main board.

Tv turns on/off byitself and it goes through all tv settings before shutting off!?


check to see in the settings menu that there is not a demonstration mode that may be enabled, some manufacturers will include this as a sales tool for the retail outlet to use

How do i set the timer? i use it for my alarm.


Which timer do you want to use? To use the On/Off Timer, press Menu and use the navigation arrows to select Time. Press Enter and navigate (up/down arrows) to select either On Time or Off Time. Press Enter and then use the up/dwon arrows to select Repeat. Select the frequency for the timer function (off, once, everyday etc.) with the left/right arrows. Use both the up/down and left/right arrows to set the time (hour or minute). Press Return to return to the previous menu and Menu to leave the OSD menus. For the On Time, you can also select the input source that will be shown when the TV comes on. (Select Input similarly to the above directions and set the desired channel if the source is TV.) The time must be for this to work (select Time and then Clock then Auto (gets the time from a digital channel) or Manual) and the TV must be in Standby mode for the On Timer to work. The TV will go into standby in two hours after coming on unless a button is pressed on the remote or the TV. The Off timer will override the TV On if they are set for the same time.

The Sleep timer is set in the same Time area or in the Q.menu (from the remote). Select Sleep time and then the length of time you want the tv to stay on before going to sleep. This is reset when the TV goes off.

The Shut-off time is set in the Time menu as well; select Auto Sleep. When this is on (on/off options), the TV will shut off after 10 minutes without a signal.

I hope this helps.

The unit turns itself on and off


Have you checked the tv on/off setting in your main menu? I had the same problem when tv would turn itself on at midnight and switch off at 12.30. Had accidently turned on the timer. Hope this helps.

Tv powers off by itself


Hi,
go to your menu on your television, go to timer and check to make sure that your timer is off. Your timer is probably set to power off after a certain amount of time of inactivity. If it is not in timer, then check power if that is a choice in your menu. Good luck!

The picture on my tv went small


Go into your picture set up menu, which should be in the main menu for the TV, and change your aspect ratio.
