Power wont come on and blue power button just blinks for a while
Sometimes it will come on and stay on for a bit but after about 20 minutes shuts off. Now the power button will just blink several times but the power never comes on.
Re: power wont come on and blue power button just blinks...
Do you hear a thumping coming from the speakers when the power switch is pressed? If so, you have a shorted video IC or your convergence ICs need replacing.

Samsung HLN507W turns on for about one minute then shuts off, three blinking lights stay on in front. It is not the lamp, nor the blue lamp cover switch for sure. I unplug it and immediately turn it on. It always does the same thing: comes on for 1 minute, then powers down - there is no wait time in between unplugging and powering on. All fans seem to work and I cleaned the dust out of it. Help.
The new battery stays on the shelves for quite some time and probably discharged. Does you ac adaptor work? Make sure it does, charge it up first a bit then start it. If you have voltmeter, you can measure its output which should be around 19 volts. Sometimes the connection to the laptop also gets loose after a while, but make sure the ac adapter has power to it.
try turning off the auto shut off feature in you set up screens . you can find them through the menu button on your remote. scroll through till you find it and turn it off.
Do not use the power button to sync. To sync device, Press + button
(volume) and Silver button (on boom) at simultaneously. LED Light will
blink RED & BLUE. Device ID should appear on your screen. sometimes it is tricky and you do have to turn on the power so try it both ways and if the power is on hold the 2 buttons for about 30 seconds to 1 minute if the light stays blue turn off and try again they are not easy to sync the code for pairing if they ask you for 1 is 0000
when it shuts down press menu and input buttons both in together on the front panel and hold in for 8 seconds and see if the LED blinks a two digit code . If so let me know the number of blinks
Were the pale blue lines real thin in a slight diagonal from bottom to top of your screen? If so you either have a bad component in the blue drive, Blue CRT socket or your Blue CRT is shorted.Try removing the blue CRT socket and trying to power up your set for a moment without the blue socket attached to the tube. Be sure the CRT socket doesn't touch any components when you try this. Let me know if the set starts up without the blue.
