AKAI 27" Wide-Screen LCD TV,

AKAI 27" Wide-Screen LCD TV, Model #LCT2785TA The red stand-by light is on. When turning on the TV using the remote or the TV power button, the red light blinks and there is the normal turning on click sound, but the green light does not come on and the TV doesn't turn on. Any idea what the problem might be?

    Over the last three weeks, we have unplugged the TV for periods as long as 4 days at a time, and have tried using a jumper across the positive and negative posts of the plug. As yet, no change. Any ideas?

    I would like to see if there is another opinion on whether we can fix the TV ourselves before taking it to a repair shop. Please see original submission and extra comment on what we have done ourselves to try to fix the problem. Thank you.

There are 3 capacitors that become defective very often on this LCDs, causing not to work properly or not at all.
The location of the capacitors is in between HS4 and HS3, their values are 1000uF/16v but you can use 1000uF/25v at 105 degrees Celsius.
If you know how to solder, this might be a DIY always keeping in mind de danger of working with devices that hold an electric charge for days even after being unplug from the AC power.
I repair these power supplies, if you need further information.

The tv is in protect mode, try first unplugging power cord for one hour, and see if this solve the problem.

    The TV does not turn on because there is an internal problem, like a short, a bad voltage, or more commonly a faulty component (IC , capacitor etc.).

    When this happen, the main Chip inside your TV detects that there is a fault, and send the TV in protect mode, activating a safety switch that prevents TV from turning on. The switch keeps turning off the tv, and that is the clicking noise that you can hear.

    Unless you have experience as a TV repair, try first keeping TV unplugged for one hour or more. This will reset TV circuts draining power completely, and sometimes can wake up the TV from protect mode.

    If it does not work, that means that there is a defective component inside the TV. In this case I suggest calling the phone number listed on the user manual to get support from manufacturer.

    Sorry to contaddict Jaime, but I repair LCD screen, for living I mean, and when power supply capacitors have blown, you do not get power in the whole unit, not even led on.

    This TV is in standby mode because there is some other faulty component, and you do not know what it is until you test it, as the TV have about 3000 components.

I have 55" akai rear


You are going to have to look for open PICO fuses along with bad bias resistors close to the ic's. You should have close to +27 and -27 volts of B+ on the chips to start with. That will ensure the fuses are good. Then trouble shoot the convergence circuit from there.

Tv wont come on and a red light is blinking. I have a Sony Wide screen projection TV model kp-46wt520


Can you unplug the TV for about 15 seconds, and then plug back in and watch the stand-by light. Tell me how many time the stand-by light blinks in regular intervals. If it doesn't blink at all, you need to change a fuse on the g-board. Once this is done run back through the stand-by blink light process, and more troubleshooting can be done if problem isn't already solved. If the stand-by light just keeps blinking with a count over ten just tell me, and I'll look for other possibilities.

I have an akai 27 lcd tv which shut down while watching. No sound no picture but the power switch is flashing red.I don;t know if it is a power supply problem or a burnt out backlight.I haven't opened the...


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.

TV -Ferguson (Wide Screen) model no: W7023U. unable to operate either with remote control or manually.


Is it possible it has locked itself? It can be locked in 3 ways according to manual.

1. by pressing the remote's stand by key for more than 3 secs.

2. By programming an auto stop.

3. By putting it on stand by after programming a wake-up time.

Flashing "red on" indicates it is locked. It can only be turned on by the remote. Press any number key on the remote to unlock it.
