These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.

SOURCE: Power light blinking red

The tv is NOT in standby mode... it does not have a standby mode !!! But what is happening is.. your tv is getting lamp errors. this can be caused by voltage drops and spikes while the tv is on... and a factory reset can correct this. OR it can be one of two problems.. Bad Power supply or defective lcd panel.

SOURCE: Red blinking light on a Magnavox Plasma TV

Here is the solution. For less that 100$ your Magnavox Plasma TV. Model # 50MF2310/37 will be running like a champ.

Issue:

Magnavox Plasma TV. Model # 50MF2310/37 screen has no picture. There is no sound, TV comes on and then after a few seconds clicks and screen remains blank.

Cause:

On the main power circuit board to Capacitors are prone to failure from over load. The caps are 3300uf 10v 105+c capacitors located to the left of the AC power input.

Service:

Magnavox will refer you to a service center. They will advise $$$ for an inspection. They will also want to charge upwards of 500$ to replace the entire board.

Solution:

1. Unplug your TV
2. Disconnect all connections from your TV
3. With assistance lay your TV on its face on a non-scratching service
4. Remove the back panel screws.
5. Lift back panel off
6. The central board is your main power board.
7. Remove all wire harnesses from the main board.
8. Remove all screws that are holding the main board in place.
9. Lift the main board out and carefully place it into a non electromagnetic pouch.
10. Take the board to a Circuit Board repair shop.
11. Have them replace the the above mentioned Caps.
12. Re-install the board in your TV.

NOTE: Replace the caps with 3300uf 16v 105+ high temp caps(preferrably Japanese caps)

This fix cost me 80$ and my time to search for other who had the same issue. Try searching for Magnavox Plasma TV. Model # 50MF2310/37 bad circuit board or Magnavox Plasma TV bad capacitors or Magnavox Plasma TV bad ciruit board.

Hope this all help, Magnavox is should take ownership for this problem and recall any tv's that have these caps in them. The worst part about this is that teh **** from the repair center that was paid 100$ to check the TV, stripped out the screw holes and damaged the case for the TV.

Portland Laptop Repair was awesome. They repaired the board and it looked like new. Check them out at http://www.laptopportland.com/

SOURCE: Sharp Aquos 32GA5U red blinking light in front but no picture!!!

Right now your TV is in " Protection Mode " because of a failed part inside. The blinking red light is a error trouble code. Only someone with the actual Service Manual for the TV will know what the code means. Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common board to go bad is the Backlight Inverter Board. It what supplies power to the screen. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

SOURCE: LG 26LG30 screen suddently went blank. Light flashing blue/red

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

SOURCE: black screen

There is a post by Stivo on this board that has helped many fix this type of problem. There are two capacitors on the power supply board that go bad and if replaced can fix this problem . The parts can be purchased at your local Radio Shack for about five dollars or less. I just did it today and it worked!!!

Possible that the suspect could be the controller board, you can switch the machine off power for sometime, check the power outlet for the correct voltage. If not the front panel must be removed to check on the board and a possible fault of the processor or memory.

Pinnacle Video Transfer: at REC, all lights turn red--except USB


how about deleting all the software of that device and reinstalling it as a new device.

the program may have corrupted the flash drive and all the data that is on it and when you pluged into any other device it may of worked a few time but that it will start corrupting everything you have plugin your flash drive into.

you are going to reformat the flash drive and re install any type of drivers for the flash drive and check every where you have used the flash drive has not corrupt any of the systems you are using.

let hope we got it before you loose your intire system due to corrupted software downloads or uploads to flash drive and computer system and this may include a network if you are on one.

Sounds like the hard drive has had a failure, you need to get a replacement one, and reinstall it, along with the opperating system, and any other programs that were on the old one.
