The tv does not stay on or off. When you try to turn it on it keeps flicking on and off till you un plug it so you do not loose the tube

TURN OFF AND WAIT 10 MINUTES,MAY RESET ITSELF.

open the back cover then tried to dis connect the supply going to the inverter board for the screen back light whci may cause of shut off. let see if the indicator will stay to green and not turn to red.

With the phone UN-PLUGED and powered OFF. Hold the home button and plug into a computer using I-tunes. Continue to hold till the restore screen starts on the computer. You will restore the device to factory and loose everything but it will be useable.

The button is probably stuck down. Try rolling the button as this will sometimes "un-stick" the button.

Keep in mind since you cleaned it out, only have the AC adaptor hooked up to rule the battery out. If the laptop stays on with only the ac adaptor hooked up and doesn't shut off then you know that the battery is faulty. If it still shuts off even with just the ac adaptor hooked up then it could be the ac adaptor.

Also check one more thing, with only the ac adaptor hooked up, wiggle the cord where it plugs into the laptop and see if the laptop shuts off, if it does then the dc jack on the motherboard is loose and needs to be resoldered back into place so it stays put.

if the sound goes out its not a tube problem . a bad tube would have no effect on the sound .you problem (my guess) is in the power supply . a modern tv power supply has parts of it that stay on all the time unpluging it is not the problem its when you plug it in ! the power supply gets a JOLT . you might get away with it ,you might not . thats why we install surge arrestors on power plugs and with expensive tvs i recomend a UPS a power unit that keeps the tv powered even wnen the line power is out . thats keeps everthing in the sets nice and even ,so the tv lasts longer ... a modern tv turned off uses about 1.40 in electric a YEAR in standby mode , so what are you saveing if you send you set to the landfill early and have to buy a new one ? over 1.40 in electric ? . turn down you water heater or something else simple dont be blowing out you electronics for the sake of a few cents ..... good luck .... if this answer helped please rate a 3 or 4 , this high rateing will hepl keep me in the paid answer department . thank you

the problem of your tv is the flyback...the power is fluctuating that makes the power light flicks on and off continuously.change the flyback,the flyback is apart that have a cap and connected to the tube...

there are some boards in the tv that plug in (push down) have the power off and unplugged have a look around, and see if any boards have come loose, stay away from any thick red wires (EHT) DO NOT PULL At the Gray Rubber Caps that go to each gun (tube) RED GREEN Blue, this can carry a heavey charge even if the tv is off and has been for days, regards mark
