Turns off & on by itself - LG 55LE5400 TV

try to unplug it for 15 minutes, if tyhat does not fix it, yo can reset all funtion to default, that will take care of it

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/tony_a41fa0b801734e2f

sounds like a defective str power regulator ic .......but my advice get a tech to resolder all the pins at the power suppy board area, there may be some open pins that triggers the on and off episodes

Check its mechanism for fault.

One of two things can be the problem...one the bulb is bad...two the ballast is bad. If the bulb is not bad then the ballast is...it can usually be fixed by replacing a resistor on the board itself...it is labeled R3 and is a 1000 ohm resistor

disconnect the additional speaker it cause overheat your system or it may damage.

Hello jayPRICAN,

You do not say what kind of speakers you are running on the amp and that can affect how you troubleshoot the problem.

Most often, a wiring problem such as a faulty ground or short in the speaker wires will cause such a problem. Here are the most likely causes for the amp to go into protection.

1) When a speaker wire is shorted or grounded.
2) Overheated.
3) When a ground wire of the receiver/head unit or the amp itself is not properly grounded.
4) When the amp itself malfunctions and a DC is sent to the speaker output.

First check your power, ground and remote turn-on wires. Then disconnect the inputs and speaker wires. If the amp does not power up normally with all the other wires disconnected, the amp itself is defective. If it does power up with everything else disconnected, reconnect the wires one at a time to determine where the problem is located.

Hope this helps.

TRY BLOWIN IT OUT

take off all your speakers cables from amp and test if it is fixed you will have a problem in your cables or speakers itself-if not you have a problem in amp itself and needs to repair in service center.

Have you plugged the amp into the AV9000. Check if the outlet you are using is switched or unswitched. Changing the outlet will most likely do the trick.

Let me take a stab at it There are two types of resistance... Static and dynamic. These resistance change depending on the position of the cone. Now im guessing the short bursts of bass are not small ones. If the cones are forced further than allowed the resistance of the combinded drivers may drop below the rated impediance for the amp...causing the amp to into protection to keep itself from over driving itself (the less reistance a amp sees the more power it will produce, till it essential blows itself up)
