Re: akai tv 27"
This model is notorious for power supply problems (mainly bad filter capacitors). They are large electrolytic capacitors located at the top of the switch mode power supply (SMPS) board. Most of the time they are easily spotted (the tops are pushed out in a dome shape rather than the flat top they are supposed to have) but it could be something that is not so easily detected. At any rate, the power supply is probably to blame, and unless you have knowledge in electronics repair, it will have to be serviced by a repair tech...

The power supply might have a shorted/defective diode(s), blown resistors, capacitors if the light is blinking on the front of the LCD.
I repair these power supplies, write to [email protected] if you need further assistance.
I have a different thread going, but saw yours and had a question. Is your light blinking steady and then off? or is it a blinking erraticly or even flickering? My bad caps (15 of them) were all on the secondary side of the PSU. I have been told (thanks to Jaimie Hernandez) if you have a steady blinking, then it is very likely that you have a bad zener diode Z3(27v/1Watt) shorted in the primary side of the power board. If that diode is shorted, it's very likely that 2 10 ohms resistors might be open, these resistors are connected to the cathode of Z3. Also check for bad caps on the Primary side.
I had a huge incentive to fix the TV, it is my wife's TV and she has been in my Man Cave since it died. How about that incentive.
I would suggest to start by measuring the voltages from the power supply to the main/back light circuitry. If the voltages are low or jumping up and down, that means a defective power supply.
If the red light is blinking, the power supply has a shorted component.
Let me know if you need further assistance.
I own a Akai TV but when we bought it, it was working fine. Then we moved it to a different position and plugged it in.. Now the red light keeps blinking and then it shuts off.. then about maybe a minute later it turned on by itself. can anyone tellme what the problem is???
