90% of the time this is capacitor related in the power supply, Remove the back and check for capacitors that are domed shaped on top, Replace these and all should be ok.

Sounds as if the cable may be damaged or a loose connection. May be cheaper to buy a new one from wallmart or similar store.

i would say this is a internal problem how long have you had it?

the only way is by bringing to a tech.i think there is no need fro self-fixing with problems like this.try tapping the tv several times then turn it on.

The 7 blinks usually indicates a high voltage shutdown situation. Without the specific model, I can;t give you details about parts etc. The options are a defective flyback transformer or problem with the voltage regulation circuits. Please update this with the model number and I'll post additional details as soon as I can.

Thanks,

The lamp cover door was not secured tightly. Door does not "push" shut easily. Got a little rough with it and latched it shut, then the tv worked fine.

Please count light flashing again. Light flash time is "0.3 Sec" and there would be pause (light Off time) for "3 Sec". Start counting after pause to next pause.

did u cheak the input cables does it do it on dvd input as well as others ?
