SOURCE: Screen powers up then goes blank after 2 seconds

Hi, was there a resolution to this? I am experiencing the same problem with LCT3285TA purchased at Radio Shack in Media, PA. Radio Shack has refused to service the unit and has put me over to Akai for the manufacturer's warranty. I'd like to know what to expect and if this problem with the Logo coming up and the unit shutting off/restarting can be easily fixed, thanks.

SOURCE: power light blinks red - tv will not come on

I bought one of these tv's at a thrift store and it had the same problem, orange light blinking and static sound coming out of the speakers, no video at all.
The problem was the power supply board, this power supply has multiple outputs that feed the circuitry, 12V, 24v, 5V.
There was nine electrolitic capacitors I had to replace to fix it, all of them were bulged they are easy to spot, I measure one of them that was supposed to measure 1000uF but measured only 65uF. you can buy these from digikey for about 50 cents each, they need to be rated at 105 deg c and the profile has to be below the heat sink otherwise they will hit the top of the heat sink, the spacing between the leads has to be 5mm so they fit in the pcb. I replaced 3 1000uF/25v, 3 470uF/16v and 3 1000uF/16v and that fixed the problem, I bought this tv broken for 100 bucks fixed it with 6 bucks.
Good luck, don't perform repair if you are not familiar with dangerous AC voltage inside the TV.

SOURCE: VIDEO BOARD

Your tv is going into an error protection mode upon startup. The problem is probably not the video board. When the tv starts, it checks with the cpu to confrim voltages, if a voltage is off or there is a short somwhere, it will prevent the tv from starting up by clicking the relays to power off the high voltage of the tv. The problem could be the power supply, zsus board or ysus. Its hard to say without opening up the back of the set and testing some stuff with the meter, but normally its just a shorted cap, worst case you blew out a fet.. But easy to find if you know what your looking for.

Use a flashlight to shine light near the screen in a 45 degrees angle when the TV is ON, press menu to see if you get fainted dark video in the background. fainted video indicates that the backlight is defective.
This type of failure could be due to a lower backlight inverter voltage as well.
Check this link for availability.
Let me know if you require further assistance.

Sound but no picture on a akai lct3201td


There could be 2 failures with your TV:
1. The power supply might no be providing 24 volts to the back light inverter board or the voltage is low.
2. If the voltage is normal then is more likely a defective back light inverter board.
The best way to know if you have a back light inverter problem would be to shine the light from a flash light near the screen and observe it from a 45 degrees angle and you should be able to see a fainted image. No image at this point might mean a power supply failure. If the image is there but fainted, then the back light inverter board is defective.
Let me know if you require further assistance.

Can't get anything on the screen


Unplug the power cord from the TV set and leave it unplugged for 5 minutes. Plug the power cord back into the TV and turn it on. It should work. This is not an uncommon problem for the Akai line.

I have the same problem. My Akai 27" flat screen shuts off inconsistantly. Sometimes it will stay on for hours and then we have to turn in on every 2 minutes. It seems to be getting worse. Is there anyone who has found a way to fix this?
