My LG 50PS3000 is shutting down after 20 minutes of running and getting progressively worse

Hi Liz, I am sorry about your issue. Please remove the HDMI cable from the receiver that is connected to the TV as a test. Check and see if the receiver stays on. If it does not the receiver would need to be serviced. Thank you, Onkyo USA

Sorry to get your hopes up but I have a similar problem with my 2005 Yukon Denali. How long does the truck stay running before it shuts down? Mine started out with short spurts of the truck shutting down while driving. It slowly progressed to the point where it will only run for about 45 seconds. Originally the truck would sputter the gauges would die and then the truck would die. It slowly progressed to the point where it only runs for 45 seconds and there is no signs before hand. Does any of this happen to your vehicle? I have checked all of my cables and the main ground wires. Along with changing a few of the relays. Nothing has helped. My problem started with an electrical component heating up and quitting. Now it doesn't matter how hot it is in only runs for a couple seconds.

ngine stalling issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

she is having trouble because she knows them capacitors are going bad...... replace them... but it nay be more than that... dont give up on finding this problem, because you may find a breakthrough!!

I had the same problem on my Env. Try deleting the Back Up assistant software on the phone, then load a newer version. This fixed my phone.

have you checked your auto shutdown timer?

Have you replaced the fuel filter?

The button on the plug is a GFI. Ground fault interuppter. Like on your hair dryer. When the unit is running, or has just tripped out, feel the plug and the well receptical. If either feel warm or hot, do not continue to run the A/c unit. Get an electrician to check for a faulty/ worn/improperly wired outlet. The units tripping out for a reason.
