Are you sure that the power supply is the problem? These sets have protection circuits built in that shutdown the power if a problem is detected. What are the symptoms of the problem? Perhaps we can walk you through the repair. Typically Akai schematics are not available outside of the repair centers.

Please try a hard reset to turn on the TV

Posted on Jul 29, 2008

  • dewan nafees ahmed Jul 29, 2008

    leave the unit plugged off from the wall power for one night

    and then again turn ON the unit

    if it comes ON then problem may be a minor one.

    else there may be any damaged capacitors in your power board.

    you will have top replace them as soon as possible before they damage more and start leaking in your power board causing a major damage.

    thank you


  • dewan nafees ahmed Jul 29, 2008

    you can find few big capacitors in the power board.

    you need to just replace them

Hitachi tv turns on then sometimes it won't


The clue is does the power light come on or not, several of the older ones had a problem with a relay in the power supply, unplugging set one or more times would allow set on.

Tv goes off then comes back.


Sounds like you might have a cold solder or bad connection at the power supply. Don't fool with this yourself. TV's today are very delicate and you need to take it to a professional. It probably won't cost you much. Let him take a look at it, give you a price for repairs, then let him fix it for you.

My toshiba RC-3910 tv turns on but 10 mins later it turns off and it wont turn back on why


hello!
it seems, like the problem of your TV is the power supply module, particularly 12v power supply I.C. chip.STRW6735 or similar. I've replaced few lately with similar problem TV. It might have a few bad electrolytic capacitors on the board, as well. Solution: if you are possess electronics technician skills and have all the necessary equipment and parts , you may do the job yourself. Otherwise, look for replacement power supply board, preferably at used boards distributors(shopjimmy.com or similar). I won't recommend to buy used on e-bay, unless it has been rebuilt. Or, remove the board and take it to local TV repair shop for rebuilding. This way you may save a few bucks.
Good luck,
Alex.

The tv wont power on at all


Hello,

Your TV Won't Turn On
If your TV won't turn on, you should check the power cord. Make sure that it is securely in the wall plug. Sometimes the power cord has burned out and needs to be replaced. You may also want to check the batteries in the remote to make sure that they are working properly. If otherwise
Common problem with this TV is the power supply module.
Check the power supply; look for bad caps with leaking/bulging tops, check to see if you have standby +5vdc at the power supply connector, the front red indicator will not be on if you do not have this +5vdc standby voltage due to shorted out power transistor and zener diode, if otherwise, Power supply board just die.It can be dead at anytime.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

I hope this will help to solve the problem.....

I have RED verticle lines all the way across the screen fro top to bottom 10 minutes after I turn my Panasonic PT-52LCX65 TV on. Is there a solution?


Hello
Check and replace the main filter capacitor in the power supply section. Replace all of them in the secondary section of the power supply too. The problem is due to insufficant smoothing and regulatio fo the power supply section. If main smoothing capacitor gets value deveoped, it won't supply enough voltage to the switching section, and switching section also will go inefficient. Replace all of them. It won't cost not much. OK.
