Re: Keeps turning off

This unit has a common problem with fans. If one of the cooling fans is intermittent the unit will turn off when the fan fails. A qualified tech with a service remote can get into the service menu and on this unit the is a menu line that shows pwr down failures.

Kindly do not keep attempting to turn it on, as you are likely to spoil some other boards/parts/components of the TV. Look for any loose contacts in power out let, RC jack, cable and socket. In order to ensure, it is not caused by the input device, connect a DVD player
and see. Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.

Hello mrdavidmetca,

Welcome, and thank you for using FixYa!

I would start by pulling the batteries from the remote control. Manually turn the TV off and then back on, manually. If the issue resolves, replace the remote.
If the issue continues; you will need to find a local TV Repair Shop and have the Tuner Board replaced.

Have a great day!

I have an LG 42" 42PX4DV Plasma, keeps resetting itself.

Do you use a regular antenna, or cable/satelits tuner?

I use only satelite tuner, and had the same problem on a differnt TV. I solved it by connecting a regular antenna (actually just a piece of cable) and go through the search and store routine once. Then the TV remembered that it was configured. Before that it thought it was "fresh out of the box" every time.
