Your description of the problem points to a power supply in the process of failing.
If it was mine, I would leave the set unplugged overnight, remove the back panel of the set, locate the power supply (likely on a separate board related to the incoming AC cable and will have larger components on it), look for an assembly number (often on a printed label), contact the manufacturer's service company and inquire about replacement or repair cost.
When you plug it back in, note whether it behaves normally at first turn-on.
If is does, this tends to support the suspicion of a failing power supply since some of the passive components in it have had a chance to recover before weakening again.
Modern supplies are a good bit more efficient than 'linear' supplies of yore but are far more complex and much more dependent on quality of components.
SOURCE: It will not power on when I press the power button.
try to run diags, press and hold fn key then press the power button an release them both at the same time when the computer turns on, check for any error message, or try to reseat your memory modules too

your speaker are hooked up wrong.or there may be dust in or on the terminals.i used a q-tip with rubbing alcohol and wiped them down.hook up the speaker cords properly and try this again.if this does not work then unplug the stereo and let it sit overnight and try again.
SOURCE: When I press power, light blinks for about 15-20
Your television is in need of repair. Hard to tell what exactly needs to be repaired but when the power light blinks in that way then this is the TV's way to tell you it needs to be serviced.

I recently repaired a GX250 that refused to turn on (flashing power led), and apparently this fix works for most other problems too, including "no disc" errors and no sound output. 193 views
