Look into the convergence circuit area, check the convergence amp's, bad solder the convergence module, & for the possible bad stk's.

    I have mentioned the list of no. of flashes and their solution:

    ONE Blink--- not used for the self-diagnosis
    TWO Blinks---B+ over current protection (OCP) , unit goes to the standby
    mode then displays the 2 blink fault. Could be a short in the power supply of
    any of the circuits.
    THREE Blinks---B+ over voltage protection (OVP), unit goes to the standby
    mode then displays the 3 blink fault. This is also a problem in the power
    supply circuit, check T603 and R672.
    FOUR Blinks---No Vert. Deflection (V STOP), Screen goes to a single
    horizontal line then the video signal muted. Check IC1509, Q1505
    FIVE Blinks---AKB circuit (AKB), the timer/standby indicator blinks for about
    30 seconds then goes to the self-diagnosis function. Something is wrong with
    the video. Check video out, Q705, 732, 761 and other components on the C
    board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking,
    try turning up screen slightly.
    SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
    function immediately. Check C515 & 516 and the jungle IC, IC206.
    SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k
    and the unit goes immediately into safety shutdown. Check power supply
    regulation and horizontal circuits.
    EIGHT Blinks---Problem with the audio (AUDIO), unit goes to standby and
    blinks the self-diagnosis code. Check IC406 audio amp, PS401 and 402.
    Intermittent problems ?? This is a great feature. You can also bring up
    these fault codes ON-SCREEN to see a list of the problem numbers with the
    abbreviation of the problem and the number of times this problem has
    occurred. This is slightly different than entering the service mode. To see the
    diagnostic screen, Press the following buttons:
    Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up
    a screen with a list of the problems and number of times they have occurred.
    Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC.
    We have repeated them in parentheses in the text for the "Blinks" described
    above so you can correlate between the diagnostic screen and the blink
    codes.
    So, now that you know about these self-diagnostics, how do you use them?
    Say that you have a set with a black screen. You see that the LED is blinking
    4 times....This would tell you that you have no vertical and that is why the
    video is muted. If it was blinking 6 times, you would know that you have a
    horizontal fault.
    It's not a sure cure, but it's a little better than a poke in the eye with a sharp
    stick.
    IMPORTANT: after you repair the unit, PLEASE clear the values on this diagnostic screen. These codes do not reset themselves after the fault is 0 corrected, so if you don't clear them, you'll be seeing "old" fault codes the
    next time you enter this screen. Clearing is done by going into the service mode ( display, channel, 5, volume plus, then power ) then press 8 and Enter, which of course returns
    everything to the factory preset condition.

    Please don't forget to rate or accept the solution

You seem to be having a problem with the power relay. You may have to get this replaced. It could also be an issue with some other component on the power board/circuit.

I recommend getting a qualified TV repairman to check this and give you a correct diagnosis, as some testing may be required to correctly isolate and identify the faulty component(s).

    I dont recommend you doing this if you have no prior experience, but you will have to replace the capacitors on the board. There are a total of 19 capacitors: 3x 1000uf 16v, 2x 470uf 16v, 3x 470uf 25v, 2x 1000uf 25v, 6x 1000uf 35v, and 1x 470uf 35v, as well as the 2 main filter capacitors that are 100uf 450v.

    You can get the full service manual from here:
    http://www.nodevice.com/manual/newmans/l...

    It will give you details as to the location of these capacitors. You dont have to replace them all. Just look for the ones that have swollen tops..they are faulty.

    Once again, beware when dismantling TV's, as there are voltages inside that can KILL , even if it is unplugged. In my honest opinion, it would be best to let a qualified professional do this.

    Kindly take a moment to 'Accept" this solution if it was helpful to you.

  • Priya darshan Jun 15, 2008

    is it possible to turn tv on manually? if it is, problem is with remote
    control. if it isn't, i believe its a problem with power supply.if it is too high, tv will not turn on.Front lead blinking red indicates that it is gone into the standby mode.
    I strongly recommend you to get it repaired.

  • Priya darshan Jun 15, 2008

    Please cooperate with Irishdruid.He will help you fix it up and make sure you rate his solution.
    Hemantraj that list is only for sony TV models not for Akai.

My akai television won't turn on


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

AKAI LCT2715 will not turn on gives blinking


This series of TVs has a famous issue with the power board (part number MLT166A or similar). Several capacitors and zener diodes burn out causing some resistors to burn as well. If you are capable of doing component level repairs check capacitors on the board and zeners Z2, Z3, Z4, Z5 and resistors around them. If you prefer to spend hundred bucks and simply buy the working power board for it - ebay is your answer.
