We were watching tv, and it was a storm. My lights went out and the tv turn off, when we turned it on again it wouldn't show picture but you could hear sound. We waited a couple of months to actually purchase another bulb, and that didn't seem to work. The volume abd power buttons started flashing and it seemed like it kept turning on and off again.

i found something on internet for your problem.

Your surge protector did not function properly, contact the manufacturer of the power strip.

Something died in there - perhaps a capacitor or a solid state device just blowing and cracking into pieces. happens. Open up the set and see if you can spot it around the power supply area.

That's because somehow the lightening caused a fault in the power board.
Ypu can try an unplug for 2 hrs and then reconnect and start again If that dosn't work you will require intevention to replace the power supply

you have defective flyback

hi everyone, well i,ve solved our problem. i had the same head bashing problem for months,tried everything.what you have to do is turn all display settings to 0 and then run tv for several hours like that,then slowly bring up brightness and colour only leave contrast at 0. i,ve tested this for a week now and bingo the light show is over at last,my god the relief.good luck everyone
