Note that myself I do not send those $26 phone offers that you will receive , they are automated by the website and I`m not available for it at this time but another expert might be if you`d rather do this on the phone .
Otherwise you can just decline if you don`t want it .

I do not want to spend $26

No problem , as i said above just decline it or ignore them

Ask Your Own TV Question

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 ?

Customer reply replied 2 months ago
No storm or anything like that. It was working fine when I turned it off and then would not come back on...no lights, sound, nothing.

O.k then from what you described this could be either caused by the power supply or main board which is common with those tv`s

What i would suggest here is getting the repair kit that includes both boards for $50 and also has a video to show you how to replace it
