Proscan LED TV Will power up the red standby light & standby on amber when turned on but does not show picture or sound unless I unplug and replug over


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Power light flashing amber


Follow the steps given below. (Please be careful when handling computer electrical components like batteries and AC Adapters)
  • Remove the battery and hold down the power button for few seconds (to drain all remaining power)
  • Power up the computer without the battery with the A/C adapter plugged in.
  • Wait for few seconds and plug the battery back in
After a few tries the computer should start charging normally. The amber battery stops blinking and turn green when fully charged.

Pushed the on button, the green light comes on,


Green light comes on, what about other indicator lights? Is there activity like fans humming. Try to take out the battery and power up using the ac adapter only.

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
