47LG50 Stuck In Standby Mode

I have a 47" LG LCD TV,model # 47LG50. I purchased it 2 months ago and it has worked greatuntil this morning when it went in to stand by mode and I cant get itout of it.

So far I have tried two remotes, pressing the powerbutton that is on the TV itself, unplugging the TV and re-plugging it,tried plugging directly in to the wall, and in different spots on thesurge protector (monster power surge).

It is under warranty butI wont be around for a repair person to stop by until next week so I amhoping I can do something myself. Anyone have any ideas?

Thanks in advance, I appreciate any help!

I am not at all sure any of this will fix your problem, but give it a try.

FIRST, read the TV directions if you have them and see if there is a specific keystroke on the remote or the TV itself to reset it or wake it up. If you already did that I apologize, but I'm just offering the easiest fixes to try first..

SECOND, if that didn't work, whatever remote control(s) you are using may have had a hiccup in its memory, especially if the batteries are weak. This applies to TV remotes and cable/satellite remotes alike. Remove the batteries from the remote, test them, replace them if needed, and retry your TV set. Even if you don't have fresh batteries on hand, just take out the old ones, let the remote sit unpowered for a minute or so, and then put the batteries back in (using the correct battery orientation, of course). Believe it or not, this often works.

THIRD, and this will rarely work, unplug the TV, short out the two flat prongs on the power plug (NOT the socket!) by touching a screwdriver to both prongs at the same time. Now set the screwdriver aside and plug the TV back in. Turn on the TV and see if it is working properly.

FOURTH, if none of the above procedures has fixed the problem, and assuming you are using a cable box or a satellite receiver box, the sleep problem may be in that box rather than in the TV itself. Unplug the cable or satellite box, let it sit unpowered for about five minutes, and plug it back in. It may take a while to reinitialize before it is operable. Depending on the type of box, it may also need to have a button pushed on the box or its remote to fully power it up and put it in operating mode. This is especially true of satellite boxes, which may go dormant overnight after updating their software and program directories. I had this problem and finally found the correct button on the satellite remote by trial and error. Once I knew which button to press, the problem was solved forever. The tech reps on my satellite provider's 800 line were clueless about it.

FIFTH, if you still have the problem, and if you are using a cable/satellite box, it is just possible that the TV has forgotten the channel it is supposed to be statically tuned to in order to talk to that box. In the old days that was usually channel 3 or 4, but these days it can be almost anything. Use the remote control that came with the TV, or the controls buttons that are often on the edge of the TV set itself, and change the channel until you find the correct one that talks to the cable or satellite box. It should be obvious by what you see on the screen. If that succeeded, leave the TV tuned to the correct channel. Make a note of what that channel is, in case the problem should ever arise again.. Go back to using the cable/satellite remote control for changing the channel you are viewing.

SIXTH, and I hope this isn't your problem because it's hard to solve, your cable/satellite remote may have forgotten the correct settings to talk to its box. In this case you will need to call the
cable/satellite vendor's 800 line and summon up a lot of patience.

SEVENTH, if none of the above works, it is possible your equipment is truly defective. You can swap out your cable/satellite box and/or its remote control, usually for free, to see if the situation improves. Just take it to the vendor's retail distribution point (hopefully) near you, get a replacement unit, and install it yourself (not necessarily easy to do). However, since you have a warranty on the TV and it covers in-home service, I recommend you use that before you swap out anything else. It sounds like you will be at home to meet the TV repair technician. so try to find out as much as you can from that person, and bank that knowledge against the day when you may need it again. Good luck!

SOURCE: surge protectors

Hey Laduell,

Before anything else, it's probably best to explain the differences between power surges and flux. Power surges (also called voltage or electrical spikes) are generally caused by a sudden, massive increase or decrease in the voltage flowing through an electrical circuit. Flux, on the other hand, can be defined as the actual voltage flowing through a circuit at any given time.

Whenever an electrical device turns on, turns off, or changes modes of operation, it can cause slight disturbances or differences in the voltage flowing through an electrical circuit. Exactly how much of a difference is made may be dependent on the type of electronic device attached, though major electronics and appliances will have a larger "pull" than smaller devices, like clock radios. The more devices are attached to the same circuit, the larger these voltage differences may become.

This fluctuation in voltage - combined with other electrical, magnetic or radio frequency interference ("noise") - has been known to cause problems or even damage in some electrical devices. To prevent such damage, many manufacturers may include "noise reduction" or "EMI/RFI protection" features in their surge protectors.

As both Dynex and Monster Cables appear to include such a feature in many of their products, the price difference you are seeing may simply be related to the number of additional features that the Monster Cable surge protector offers, though this cannot be guaranteed.

If you're in doubt about your purchase, I would strongly suggest contacting either manufacturer for more information. Most manufacturers are able to provide you with detailed descriptions of their product features, and one of the two may be able to point you towards an online FAQ if one is available. Dynex's toll-free hotline is 888-305-2204, and Monster Cable can be reached at 415-840-2000.

Hope this helps you out.

Go Ahead. Use Us.

SOURCE: my HP HDTV trips my circuit brakers

1) Try with a different surge protector. The oine you're using could have a short-circuit
2) Try without a surge suppressor, at least for a day
3) Does the circuit breaker trip when something else starts running? Your microwave, fridge, dishwasher, etc.?

4) Check the user's manual of your TV, under SPECIFICATIONS. Check for "POWER REQUIREMENTS". If the power requirements listed is greater than 15 Amps or 1,700 Watts (assuming you live in the USA and your household is 110-120V), then the circuit breaker will almost always be triggered by the TV. Most circuit breakers inside a house are 15 Amps.

The only option you have is to replace the circuit breaker for one that has more Amps, but doing so on your own without having and electrican check if the wiring will hold the extra load is extremely unadvaisable. You may end up with an electric fire in your hands.

Solutions (2) Best Solution That little fella is only turned off by unplugging it. If all those little lights in America could be turned off we could do with one less nuclear power plant. If unplugging it is not an option, my wife's solution is to cover it with a piece of black tape.

remove all screws on the back of the tv, carefully pull off back cover. you will see two circuit boards one on the left (Power) and one on the right (Video) on the Video board there is a small plug on the right side with a yellow, white and red wire going into a small white connector. the red wire is what controls the orange light on the front. now that the plug is pulled turn it over and you should see a small white plastic piece that holds each metal connector on the end of the wires in. pry this piece of plastic up for the red wire and pull at the same time, the wire will come out of the connector. now tape the metal connector with electrical tape and tuck it behind something or tape it to the chassis. plug your connector back in. put the rear cover back on. now your tv will only show the vizio logo in white when you have the power on. If you wish to disable the logo for both orange and white just disconnect the white plug completely.

47LG50 won't turn on, no standby light at all. DEAD! tried different power sources, but nothing. was on, made a "bzzzddd" noise then turned off. Serious or just a fuse?

you can remove the fuse and check them with a multimeter. put a lead on each end If the meter shows a low number (normally less than 1), then the fuse should be okay. if not than you need a new power supply board. be sure at all times to have tv un pluged while working on them and always be very cautious as the do still hold power. hope this helps

If there is no code, then there is no code.

The only other option would be to buy a 3rd party remote that is compatible with both devices. Unfortunately there is no way to know if it will actually work until you try it.
