    I was watching TV and all of a sudden it turned off and the red led on the front flashes 7 times and stops and the starts again.
    I called Panasonic and they said to try a different outlet and I did and then they said that they have to send a service-person out to fix it and maybe replace parts. Luckily it is covered under the 1 year parts and labor warranty. But I have to wait until Friday. So I might just bring it to Best Buy and swap it for one that works.

    Hi, If i was in the USA I'd send my board to you, but it's a long way from the UK! I've been advised that the 10 blink problem is likely to be due to the NPMDPPNCA thick film module, circuit reference MC201 and MC301. Can you advise if these are the parts that are usually to blame?

I have a sharp aquos tv model lc-32m400x. When i turn the power on via button at the back the green light comes on for about 10secs then turns to red and flashes about every 11/2 - 2secs. Any ideas.


Those 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.

If blinks continue without any pause, the main board is faulty.
