  1. Verify TV is plugged-in and getting power.

  3. Verify the batteries in the remote control are good.
  4. Verify you have selected the right input for Cable/Satellite, antenna, DVD, VCR or Game Console.

SOURCE: TV on/off light keeps blinking red light/no sound or picture on screen

Here's a solution that I received from an TV expert in another website: "This sounds like a power supply problem. i have seen it several time on your model. i would not keep trying to turn it on it might damage something else in the tv. the reason it is shutting off is because the power supply is putting out too much voltage. a repair cost will range around 300-400. this is a great model and well worth a repair. here is a web site that might help you in finding a repairman.
http://www.nesda.com/locator/state_search.php." <-- $300-$400 is too much! But throwing away a 300lbs TV will cost a lot of $$$ for the towing and dumping too. I haven't decide what to do yet.

SOURCE: Hitachi 55VG825 rear proj television blinking light and screen doesn't light up

Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...

Yes common problem it seems with these. I can help you get the set working but this fix only prolongs the inevitable so I'm told. (more about that at the bottom) Please read entire posting before starting. You will need to take off the front panel, there are 2 screws towards the bottom on each side behind little pop out plugs. Once those are out take off the panel (pull from bottom, sometimes the round clips at the top come off, either glue them back on the panel or leave them out). There are wires attached to the panel, you can either unhook them or just take them out of the "twist tie" holders and move the panel out of the way to the left. You will now see a thin panel. Remove this one also. Once that is off you will see the bottoms of the 3 glass tubes and on the "floor" of the set there is a group of 6 small knobs. This is called the focus block. Each row of 3 knobs are labeled either screen or focus, also, there should be 3 letters R G B (Red Green Blue). (We won't be adjusting the focus knobs).You will need to adjust the Blue screen knob (on my set it was the bottom left knob). If the set will stay on for a little bit you can adjust it with it on. Once you have found the correct knob (don't worry about the white paint) turn the set on, once you see the picture slowly turn the blue screen knob counter clockwise until the blue diagonal disappear. Be careful not to turn this knob too fast while the set is on. Keep in mind, it may take a little bit to break off the paint. You will see the screen turn back to normal as you turn the knob. Adjust it just until the lines disappear This should solve your problem. If the set won't stay on, with it off turn the knob about 1/8 turn counter clockwise then turn the set on. Once it is on you can fine tune it. Adjust it just until the lines fade out of sight. (You may have to adjust back the other way until the lines show up and then back it off again). Remember to turn the knob slowly. I have heard people getting charged a lot of money for this. I was also told that this is compensating for a dying component(s) all I know it has bought me at least a year. I also read that someone has gotten several years out of there set w/o repair just by doing this adjustment whenever its needed. (once the lines start presenting themselves). I can't see spending big money on these sets when you could put it towards a new set so I will keep it going for free as long as I can. I hope this works out for you. I'm tired of typing so good luck and post if you need any more help. BTW this adjustment works if this symptom presents itself in green or red also. Just substitute the blue knob to the applicable color. Now go put your TV back together :)

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Lg 47ld520 red light blinks 3 times then blue


The LG web site recommends that the consumer schedule a service technician if the
set fails to turn on... no help on the red light blinking.
The LG service technician will want to know about the blinking lights, though.

Here's your TV User Manual (in English) for $6.99:
http://www.devicemanuals.com/model/LG_47LD520_manual.html
(couldn't find one free)

The LG site has nothing in the way of a users manual (just a 2-page spec sheet), and
no technical support. They list a parts distribution place though, at:

epd_web_logo.gif Encompass Parts Distribution 1655 Lakes Parkway
Lawrenceville, GA 30043
Sales: 866-779-7906
Fax: 800-552-1431
