i have access to TV

Please try this:
-unplug the tv POWER cord from the wall outlet.

-disconnect all antenna/cable/hdmi/audio/video/etc cables from the tv.
-wait 3 full minutes then plug in ONLY the tv power cord and try to turn on using the button on the tv, not remote.

REPLY back here and tell me what happens.

pressed only the power button. red light on but nothing else

Since unplugging didn't help- I'm very sorry to say, this is going to be an internal failure that requires diagnosis and parts inside the tv be replaced. If you want to DIY, let me know and I may be able to help you with that here. Substantial electronics experience is required on your part. Otherwise you will need to use local repair shop. In home repairs start at $250 on this model.

Regardless of what you decide to do, I really want you to be satisfied with my service, so before I send the rating options, I want to know if you inclined to give me 5 stars for best service or if you require something more.

Note: You should not base the rating on the fact that your tv needs parts or services outside of our control.

Customer reply replied 3 months ago

You're welcome. All the best.

Please do submit a 5 star rating at the top of this page so that I am at least recognized for helping with your question. If you are having issues with the rating try refreshing the page.
