This usually indicates that the remote receiver or IR as its call is faulty in the television, this is a releatively cheap part to replace but you will need to know how to unsolder electronic componets and resolder them. But before replacing the sensor check the supply voltage to it, it should be 5 volts on one or two of the pins if the voltage is there then replace the sensor..

What make and model remote are you using?

LG 37LC7D 37 in.... | Answered on Feb 14, 2010


It is likely a capacitor on PSU that is starting to blow. The TV must be taken apart by a technician, tested and fixed replacing the faulty board, of the component.

If it is PSU, for example, he will either replace the set of capacitors, or replace the whole board.

More faults, concerning different parts can cause the TV shutting down after a pop noise. The TV must be disassembled and tested to find out.

The best thing to do is contacting LG at the number listed on the owners manual. They will give you instructions on how to get it serviced.

The caps (capacitors) in the powerboard are going out. This is a very common problem in all class and price ranges of modern lcd and plasma tv's/ monitor's. I don't know if this problem has been like this for awhile or it just started, but either way, if the tv takes an abnormal amount of time to "warm" up then it most likely will go out all the way sometime in the (near) future. If you have a tiny bit of will and knowledge ypou can open the unit and get to the print board. Examine this for "popped" capacitors, they will have a buldging top instead of a flat one. Im gonna try to include a pic of them here, if i can get it this time, I've tried bfore lol. But you can google image a "popped" or "bad" capacitor and you would be able, with ease, to diagnose if you have any of these. Usually only one or two. Radioshack sells capacitors (couple anyway) for $1.59 each. MAKE SURE the replacement is of the SAME voltage or HIGHER, or you will be right back replacing those 2. Every capacitor has a negative pole marked with an (-) on the side of the capacitor(by one of the "legs", always puit the negative (-) "leg" of the new capacitor in the same hole in the printboard as where the previous negative (-) "leg" of the capacitor was ( a capacitor with the negative and positive "legs" put in backwards will result in the new piece "popping" as sson as you turn it on!!) make sure the "uf" rating (for example the most common popped capacitor is the 1000 uf) is the same as the one you are replacing. I needed 1000 uf, 105 c and 26v (volt) ratings for the 1 capacitor I needed to replace to fix my LG 19" lcd panel monitor I found by the trash that the light came on off, but it didn't come on. I replaced that capacitor with ; 1000uf, 85 c and 36 v (volts0...It works fine eventhough the volts and the temperature rating (36v and 85c) was not the same as the (26v(volt) and 105c ) capacitor I removed !! Further, I've replaced capacitors that had the celcius rating of 105 with the only ones Radioshack had, namely 85 c(celsius) they have been working great, but I'm not sure about any effect, nor have I heard or read (yet?) about that making an urgent difference. Many threads that I've read people have done the same, so we should be ok (my stuff has been running good for a while longer then most brand new ones!.............(all these ratings ; 'uf ' and 'c' etc are on the side of the capacitor you are replacing and on the side of the ones you are replacing them with)...For all this all you need is the cheapest solder gun u can find (I bought one for $7.99 at Radioshack), a camera (to take pictures as you go to remember how to reassemble the unit) and, once you have your materials, 20 minutes to replace 2 or 3 capacitors and you are good to go...Most monitors and tvs (lcd/plasma) I've seen you have to lay flat on the ground/bed/blanket etc, to work on (screen side down). Usually there are 2 or 3 screws (or a few more) to remove, then you will have to carefully (its comes off easily most times)insert a flat screwdriver inbetween the casing and gently pry it up as you go around the whole frame. Sometimes you have to remove the little washer arouind the cable input orso, just be gentle and you cant go wrong. Once insidet here will be a box with wires running to the sides etc...unplug, gently, these wires and open the box. Inside you will find 2 or 3 circuitboards, check them all for "popped" capacitors, replace, reassemble and plug it in....Have fun becoming an overnight tv mechanic lol!

If this helped yopu (or not) please rate!, thank you.

This is a main board issue and will need service.
Some LCD TVs have a 2 year warranty.

LG 37LC7D 37 in.... | Answered on Jan 20, 2010

Most likely you will have to use the audio component input.

LG 37LC7D 37 in.... | Answered on Jan 14, 2010

Why not, if they WILL but most 3rd party coverage plans are for repair. Keep OLD or get NEW?? I would always vote for the NEW.

Good Luck, big IRISH.

Please follow the steps below:
Step 1: Connect the two RCA plugs on the Y adapter to the right and left Audio Out jacks on the back of the LCD TV.
Step 2: Insert the mini-plug on the cable attached to the right-channel PC speaker into the mini-plug jack on the Y adapter.
Step 3:Connect the mini-plug on the audio cable attached to the left-channel PC speaker to the mini-plug jack on the back of the right-channel speaker. This completes the PC speaker connections to each other and to the television. The TV sends an audio signal to the right PC speaker, which separates the signal and sends the left-channel stereo information to the other PC speaker.
Step 4:Connect the AC power plug to the back of the right-channel speaker and plug the other end into an electrical outlet.
Step 5:Switch on the speakers and the television to enjoy audio from both the TV's built-in speakers and the external pair of PC speakers.

yes it is just rember to un plug tv first and were all wires go back ( take picture )

LG 37LC7D 37 in.... | Answered on Dec 12, 2009

Most likely it is the LCD Panel causing this and it could get worse. The only fix is to replace the LCD Panel and if it is out of warranty it would be too costly. We are talking replacement cost of $900.00 for the part its self.
