Hello sir Ibsen,

The first thing I suggest is to check the power cord and its connection if the light indicator on the front of TV won't turn on..Used multimeter or volt meter (range to AC) to measure the voltage..If no voltage,replace the power cord because the cord have internal wire break or open connection that can't visually check..

If the power cord is good,the possible problem is power supply board inside..
Hi, i am having problems with my TV since day - 2_21_2012_1_52_43_pm.jpg
It cost $89.95 to this site
But before you decided to replace the power supply board please try to reset or reconnect all connectors on all boards inside specially on power supply unit..

Also I remind you when the TV already open the warranty will void...

If you more queries and clarification please feel free to reply to this tread..

Hope this solution will be helpful..Thanks for using fixya marketplace and choosing my service..

    In fact the model is not the one listed. It is the XVT 473.
    When i plug the power cable, the VIZIO logo switch on and it gets orange. Remain orange for ten seconds and then starts blinking between Orange and Green 24 times. After that, it gets orange and nothing else happens. Logo remains orange and it does not happen anything. I press any button but logo remains Orange and the TV does not power up.

    kindly try to open the cover of your TV then reset or reconnect all connectors inside like what I suggest to my first solution..

    Because all TV before delivered to the customer it will test and pass the QC.however,sometimes customer like you receive a defective one that cause on vibration through delivery...So I suggest to reconnect all connectors inside..

    Please try this first and let me know what happen..

    Note: this procedure can void the warranty if any..

    Hi Chester,
    Nothing happened. Tryed to reconnect all the parts that have connectors but the problem persists. have you ever saw this specific 24- blinking error before?
    What would be my next move?

    Actually sir there's no error code of 24 blinks..

    I think 24 blinks of green and orange is sounds like the TV want to turn on but there is short circuit or over load cause of faulty parts..

    Try to unplug the inverter board first and power ON the TV see what happen..If persist power off tv then replug inverter and unplug the T-con board and see what happen..if the blinking LED disappear replaced the unplug board..

    There are basically 4 boards in the Tv.
    1- One on the Left (narrow board) I believe the backlight inverter. I have disconnected the plugs and the 24-flashing error was still there.
    2- One board in the center-left. The power Board.
    3- One board the upper-center. i believe it is the PC Board or T-con Board. I have disconnected also the plug of this board and the 24-flashing error was still there as well.
    4- One board in the middle right which i believe is the main board(the one with the HDMI outs and etc). When i unplugged this board, the VIZIO Logo was not glowing nor flashing. As if it was powered off. Theoretically might be the power board? or definitelly the main board?

    Finally I got the faulty parts..

    Base on your reply and base on my experience I can say that the faulty parts is main board..Its sounds like the main board fault to initialize the part # is (Vizio 3647-0312-0150)..But before you decide to replace the board try to check all pico fuse inside (it is marked like horizontal S) on board..check the continuity of it using meter range in ohms..

Hi, my 50inch polaroid led tv model p50led14 tv is not workin, wen i turn it on its just a blank screen, no sound ...u can see there is a back light on the tv but no picture. I have turned it off n on

Ok, it could be a couple of things. It could be the power board, it could be the main board or it could be the T-con board. Unfortunately to be able to diagnose any of these problems you're either going to need some very technical knowledge or a good working board to swap the ones in your TV out with to determine the problem.

My 19" Coby hdtv 's sound will NOT stasy .Itgoes down to zero and when I put it back up ,either remote or on tv itself ,it goes up then immediately goes back down to zero .

unfortunately the coby company has gone out of business probably because they have produced an inferior product that has had many problems, many people are posting problems with these sets. it is better you just purchase a different brand of tv and leave this heartache causing product behind.

Hi We bought a Sony Bravia 40" 2 1/2 years ago. Model # KDL40EX400. After about 14 months we started to experience something very bizarre. The TV would turn itself off. No lights on the screen. Af

At some point you have to cut your losses, this is the reason I suggest getting an extended warranty with coverage (including the maker) of 3 years, 80 of the 140 sets in our shop are less than 3 years old, if this set had that they would have to fix or replace the set----One reason I choose to answer your question (I do this here for free) is this set ought to have a error buffer, when set fails it will count the event and that also indicates where the issue is.

Most of the Sony sets for the last decade with set off and using the Sony remote: Display, 5, vol down, and POWER will if set comes on bring up a display with a number of shortened items listed----they should all if the set has this be a zero. Any with a number indicates a issue and the number indicates the number of times this event has happened.

My dynex has sound no picture 46 inch

Hi, unfortunately it sound like your television has a problem with the backlight system, it is either the backlighting bulbs or the power supply that runs them. It may be possible to reset the televisions brightness setting by keeping it unplugged for a day. Having lower brightness setting may " let " tv resume operation. other wise it'll need repairing. I hope this was of some help, Good luck, Prodzilla

JVC AV-32F702 Color TV shuts off after I power it on.

Any malfunction associated with a flashing light usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.

After a household power blips during bad weather, we have horizontal lines ....

Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .

Goldstar tv

leak of voltage going to mainboard, the 120v suddenly decrease after a whiloe to zero you mean short circuit. it is not power supply problem as you say that it drops to zero after connecting main board. it clearly indicates that problem in horizontal output section.
