The power supply board or inverter. The power supply board is the first step. Look for any capacitors that are puffed up. Replacing them should take care of the PS. Check to see if you have 24 volts going to the inverter. If you do PS is OK and the inverter is most likely bad...good luck

The infrared receiver light just keeps blinking red and TV won't power on. Tried unplugging for a little while but didn't help.


kindly count the blinking led to diagnose where the fault came from..

also try the initial check....open the back cover and inspect the power supply board for any bulged capacitors inside..

Remote won't work. Tried new batteries, reprogramming, etc. Universal Remote doesn't work either. LG #42PC5DC


Hi,
To confirmed if the remote control is working fine, aim the remote control sensor(IR emitter) directly to your cellphone camera. While pressing any button key on the remote control, you can see the flash of an infrared emitted by the remote control if it is working fine.


If you've confirmed that the remote control emitted an infrared but still the tv won't communicate with it, this is an indication of faulty IR sensor board of the TV. Check if there's an obstruction from the IR receiver in front. Keep away all of it, clean the plastic window of the IR receiver with soft clean cloth.
If the symptoms still persist, you have to replace the IR sensor board. Check the actual part no. of the board before ordering.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.
