Last night the electric went off now my tv will not come back on all its doing it flashing a green light. my tv is a mitubishi big screen medallion model ws 55615

Are the lines always vertical or horizontal? Are they black or multiple colors?

time to take it in for a proper diasgnosis and then to decide if to fix or not

If the TV is a few years old the flashing green light means the bulb need to be replaced. That's why the TV will not show a picture. Check your owners manual on how to replace.

Bad capacitor syndrome. Search 'bad caps' and model and you will find on goog.

CHANGE THE LAMP

Try to unplug set and try it again as if the set was unplugged and then the self check done it will be 1,2 which means NO ERROR detected.

Let me know also what the set does?

Hi.
The TV is in protect mode because there is an internal fault.
The TV must be tested and repaired at component level.
Call Mitsubishi at the number listed on the user manual.
You can also read my comment explaining more on protect mode here:Why my TV does not start up and remains in...

The x-sus or y-sus panel wil be the fault.Check the fuses on these panels ,if one of the fuses is open then that panel must be replaced.Not verry cheap to replace.

i hve the same problem. I turned on my Sharp Aquos lc-32d62u HDTV last night for the first time, but it is black and a blinking green light.
did you find a solution?

My tv did this, if you unplug it for a couple of days, plug it back in and push the reset, my light quit blinking, but it took about 1 to 2 hours
