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/

You cannot replace a screen that big. The manufacturers wont ship it to you. IT has to be done by an authorized service center.

What problem with your LG phone? As far as I know there are two possibilities to get this error message.One is poor signal of that respective network for which you just need to switch OFF and ON your mobile and the mobile will be able to receive the signal from near by tower.You may also get this error message when you are trying to insert a sim other than which the mobile is locked to.To solve this problem you need to unlock the phone from that particular network or use the same sim to which the mobile is locked to.To unlock your Lg phone purchase unlock code from any vendors online like

I've had "Record-blocking signals detected" on my LG RH398H-M recorder off & on since I bought it almost a year ago. Also other minor problems. LG replaced the recorder 4 times with no change in problems. I became suspicious when I found that when these messages came on I could switch to any channel, digital or analog, even the weather channel, and I would still get the same message for about 5 minutes & then everything would be OK again. Recently I finally got the chance to try something. When the message came on I disconnected the input to the recorder and the message still came on! Again, I got the message "Record-blocking signal detected" with ABSOLUTELY NO INPUT CONNECTED to the recorder!!! Of course it's impossible for the recorder to be receiving blocking signals when there's nothing connected to the inputs. I wrote to LG again and threatened a law suit but so far they've been ignoring me. I would like to hear from anyone who can duplicate the above.
