Normally, when this happens, the TV goes into " Protection Mode " because of a failing circuit board. 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 thing to go out on flat panel TVs is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. But, I can't say it's 100% the problem because I can'tactually 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 minutes so the TV can 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 flashing 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.

I keep gettin "no TV Signal" on my Emerson EWL20S5C when i plug in a indoor tv antenna. DoI need a converter box. I live very close to tv towers. HD


I cannot seem to find info on the version "C" model, but everything I find on the base model appears that is is not a digital unit and does not have a digital tuner. Thus it would need a converter box to tune digital HD channels. That said, the specs also say that the set can handle 480p/480i/1080i inputs. Thee is no mention of 720p/720i/1080p capability, which funnily enough, most US TV HD broadcasts are in 720p or 1080p. You may find you need a new set.
