Contact any service technician. Might of of its power board complaint. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

My polaroid lcd tv, wont turn on, its 16 months old, any ideas?


Try plugging it into another outlet - one which you are certain is working. If that doesn't work, you might have a bad fuse inside your TV. If that isn't it, the power supply board may have failed.

WON TURN ON


For the first step, try using the button on the TV itself.
Secondly, check if the power cord is snug, and not burnt. Sometimes after a blackout, there would be a power surge, and that might burn your plug.

If both doesn't work, the fuse in your TV may be blown, or the Power Supply may also be burnt too. If this happens, you're going to have to hire an expert to help replace the broken parts.

Note that in some TV models, the fuse can be replaced by users. If this is your case, try checking the fuse to see if it's blown or not.

Tv wont turn on


tried to unplug the tv for a while to reset the power supply and then re plugged and turn it on let see if it will turn on. if still doesn't work and no power at all, at this time you will need to remove the back cover to access the power supply board, then look for a bad fuse or a burnt parts. replaced bad parts with the same value and rating.you can find replacement at www.digikey.com.

I had the same thing happen to me a time or two and after extensive troubleshooting I found a simple solution which will hopefully work for you as well- at least in the short run:
Unplug the TV for 30 seconds or so. Then plug it in and try again.
Unfortunately you're probably going to eventually run into the same problem that I'm having now- the TV won't turn on or even light the indicator. I'm guessing it's a short somewhere that caused both issues which slowly escalated. I'm going to be working on that soon to see if I can just replace a fuse.

I have a 42inch tevion lcd tv it was working this morning, and now it seems there is no power in the tv at all. tried changing the fuse, that not woked, there is a 3 yrs warrenty on it but they wont help...


Hi,


Please check the following steps to troubleshoot your problem:-
Check that the power cord is securely plugged into the power outlet.
Make sure that the power outlet is receiving electricity by plugging a different device into the plug and turning the power on. If the other device does not work you likely have a blown fuse or tripped circuit breaker.
Replace the blown fuse or reset the circuit breaker as needed. If it happens again, an electrician should assess the problem.

If the above steps won't work to your problem contact your dealer or customer support.


Please get back to us if you have any further query or else accept the solution.

Thanks for contacting fixya.com

Tv wont turn on


Unplug it for 20 mins then try again plugged in.
It could be something as simple as an inline fuse but dont try opening the set EVER with it plugged in.
