I do not want to spend $26

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

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: replied 1 month ago.
No storm or anything like that. It was working fine when I turned it off and then would not come back 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

Looks at your tv`s serial number prefix letters , is it one of those sets ; LAQKNRGP,LAQKNRGQ,LATKNRGP,LAQKNREP

Customer: replied 1 month ago.

O.k then i`m sure what i have will do but can you check those letters i mentioned above ?
