What if the LG TV still takes a long time to turn on?

If your LG TV is still slow to start despite the procedures seen above, then the failure is probably of hardware origin. It is very often faulty capacitors. But other basic electronic components can also be culprits.

Test and replace the faulty electronic component

Often, a long-to-start LG television is caused by one or more worn out capacitors. This is all the more likely if you hear rattling when the TV tries to start.

In the case of your failure, the capacitors are not completely out of service, but they may soon be. If it comes to this stage, your lg tv won't turn on. To take the problem into consideration right now and prevent the big failure from happening, you can then test capacitors if you have electronics skills.

Capacitors
You have been warned! : risk of electric shock and irreversible damage to the TV. These manipulations require opening the TV and testing the components. If you are not able to do this, contact a professional now. Always unplug the power cable before opening the TV. If you have the right to guarantee, do not disassemble the TV or you will lose your rights. 

To test a TV capacitor, here are the main lines to follow:

  1. Discharge the main capacitor on the power board.
  2. Visually check if any of the capacitors appear swollen. If so, that capacitor is out of order.
  3. Desolder it so you can test it electrically. If no capacitors are swollen, then you will need to unsolder them all to test them. Indeed, a capacitor can be tired but not totally defective. In this case, it is not necessarily inflated even though it is well and truly out of use. This is all the more likely in the event of your breakdown because the television is slow to turn on but it does eventually manage to do so.
  4. Discharge the capacitor you wish to test.
  5. Using a multimeter set to ohmmeter, put the red test probe on the + terminal of the capacitor and the black test probe on the - terminal. If the value goes high and goes back down to 0, the capacitor is functional. If the value rises but does not fall back to 0 or stagnates on OL, the capacitor is out of order.
  6. Buy a capacitor of equivalent capacity for ten euros and put it back in the same place as the old one on the power supply board.

If you've never tested or replaced a capacitor, feel free to watch a video tutorial by typing "how to test a capacitor" in the search bar. To help you change it, here is a spareka video on how to replace capacitors :

The problem may be more global and come from a faulty electronic board. In this case, you can test the motherboard and power board to find which one is responsible for the slowness. To test the power board, you can watch this video (but basic electronics are still necessary): how to repair a samsung television that has a power failure?

Also note that a tired electronic card does not necessarily have non-compliant voltages. In this case, the fault will be difficult to spot.

Contact LG Service Center or Professional Repairer

Unfortunately, if you are unable to repair the TV yourself or cannot identify why your LG TV is having trouble starting up, you will need to contact a professional repairer. As a first step, we advise you to call LG support. An adviser will then be able to give you information specific to your breakdown and your television model.
