Hi Uzziel

The power button is digital these days. That is... it does not have the AC power directly connected to it. Like a normal appliance.
It's a Computer.
Nowadays, the switchmode power supply module converts the incoming AC power to the lower DC voltages required by the other circuit boards.
It uses lots of Electrolytic Capacitors to clean up noise in the DC power. But one Electro Cap is used to store a charge for turning on the switch mode power supply. Being Electrolytic they are prone to leaking & bulging so they don't do their job. They won't hold a charge. By pulling the plug and restarting, you have found a way to overcome the problem. But only temporarily. When the Cap goes fully bad, you won't be able to start the TV any more. Suggest you order a switch mode power module for it or take it to a tech who will replace the module. It's usually in a metal shielded small box full of ventilation holes.
I have repaired many switch mode PS but most tech's these days don't bother. They just get a replacement.
Cheers

Tv won,t come on makes beeping noise


Try unplugging from outlet for fifteen seconds. Press the power button for a few seconds "before" plugging back in. Now plug back into the wall outlet and try turning it on to see if this reset the TV's settings.

Crosley CAWC529PQ1 won't turn on.


First, you'll need to make sure you have the proper voltage at the outlet, and the power cord terminals fit tightly into the outlet slots. Based on your post, you most likely have a faulty electronic control board.
Here is the board to order.

Switch off the TV from remote, then switch off the on/off button on the TV, remove the plug pin from the power outlet. Cool off for 48 hours and then retry. If nothing works, better refer it to a qualified service technician.

no remote but tv was working with front power key? unplug from ac outlet and plug back and listen for any type of indication (noise or chirp) that something energizes inside if theres nothing then suspect a power supply problem, main fuse blown, shorted low volt rectifiers other components could be at fault.

AKAI 32" LCD HDTV WILL NOT TURN ON


The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

Try to reset first if nothing happens we proceed another solution;

Resetting the TV

Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can saved time.
1. Unplug the TV power cord from the power outlet for 3 - 4 hours.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

hope this may help;
