Facing TV Problems? Ask a TV Technician.
Hello , my name is JackPerhaps I can help you with this problem but first i would have a few questions like the full model number of the tv so could you please send me a reply when you are ready to proceed ?By the way , this is NOT an answer so there is no need to rate yet.
Thanks , a few questions coming up
Did it quit while watching it or simply would not come on today ?Any electrical storm or power blackout in your area prior to this ?While its trying to turn on , do you get the sound ?
O.k then you lost the sound and picture , it turned off while watching ?
In that case the first thing to try would be this ;
Unplug the TV's power cord and hold the power button directly on the tv ,keep holding it for 20 secs or so then let the tv sit unplugged for a couple of minutes before you try it again.Although i do not expect much out of this procedure , it has to be done to confirm that this problem can be cleared or not with a reset.If that does not do it then we are looking at internal problems with the tv.
let me know how that goes.
Ok then as I said , I did not expect much out of it but it had to be tried
If that does not do it then you more than likely are looking at a power board that failed while you were watching the tv .
After the model number 42LS5700-UA can you see letters like AUSDLUR or AUSWLUR ?
There are 2 versions of that board for your tv and you can identify it with those letters or by the part number directly on the board
O.k then you got the EAY62608801 (EAX64427001(1.4)) Power Supply
how do you want to proceed from here ?Look into this yourself or the repair shop ?
Let me know and i will help you along if you wish to look into repairing this yourself ,otherwise i will give you the details and costs you could expect.
