Hi
I'm a noob regarding electronics, but I'm willing to learn. I know I can just throw this TV out and buy another. I'm willing to try and learn how to fix this problem.
My LCD TV is not turning on. Need some help.
This is what I have done so far:
I have an Akai LCT2016 LCD TV

The tv has an AC/DC adapter producing 12V 5amps

I tested the power going into the TV which produced around 12V

I opened up the tv
http://g33stone.com/lcdtv/DSCF0100.JPG
I plugged the power into the board and these are the readings

I noticed there are 3 leads coming off the power connector and onto the board

Questions:
- Is the power supply really pushing out 5amps even though the voltage is correct? Does this matter?
- There are 3 leads coming out of the power connector on the board. What are they for (I'm assuming one is for ground?)? Why does it have only 4.3V and 4.4V? Is there a problem with the connector? Shouldn't I be getting 12V?
- Are there other areas I should be testing?
Thank you for any advice,
Brad
