AKAI 32" LCD HDTV WILL NOT TURN ON

Yesterday I tried to turn my TV on and it did nothing except display the red standby light in the front of the unit ( when the set turns on like it should the red light turns green). I unplugged the unit from the outlet, waited 10 seconds, and plugged it back into the outlet and the TV turned on. Today I tried to turn my unit on and nothing happened except the red standby light like yesterday. The unplugging and plugging thing did not work either as it did yesterday. I did notice that when I plug the TV in to the outlet I can hear a high pitched sound coming from the back of the set, but when I push the on/off button nothing happens except the red standby light. The TV is dead in the water.

Please Help!

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

Find and replace the following caps, Ec18, 19, 20 / 1000uf/16v,
Ec9, 10 / 1000uf/35v, Ec14, 25 / 470uf/35v should resolve the problem. You can get the caps at almost any electronics supply.
This is a common problem in this unit.
Good Luck!

TV ON STANDBY MODE


The blinking light on the front indicates a shorted part in the power supply. The power board will need to be replace or repair to restore the LCD functionality.
Let me know if you required further assistance.

The power supply most likely failed on your LCD.
How old is your LCD?

Akai LCD TV wont turn on


Hello davidshu,

The issue seems to be a power supply problem. The television has a switching power supply. This might be the problem. I would suggest getting it repaired at a television repair shop due to the possible complexity of the work that needs to be done.

AKAI LCT3285TA seems to be stuck in "Standby"


Greetings,

We own a small TV repair shop in Ohio and have ran into similar problems with this TV.

To fix this problem we replaced 3 caps near and in the powersuppy of the TV.

This TV is very sensitive to electrical problems ( more then most if that's possible) so check the caps near the PSU.

Over all this TV is a fairly decent product.
