I ave a jmb 66w widescreen TV and over the last couple of days when I try to put the ttv on the red power light is on and if I try to put the TV on the green light comes on for a second as if the TV is going to come on then it goes back to red at first the TV came on after a few tries but now it just won't come on... can anybody help please

I'd look into the manual under troubleshooting (if you haven't done so already). Those LED's are telling you why the TV isn't working.
