Hello

Welcome

So the blue light means the set is in the ON mode so if you press the menu button of the sets own remote control does the menu come up please?

No. Wasn't sure if it had to be attached to a signal to see anything. I don't think it does. Should show a menu when it comes on correct?
Customer: replied 7 months ago.
also not sure the remote works, but should be able to press the side buttons correct?
Expert:  Anthony_Infotech replied 7 months ago.

You do not need a signal to see sets OWN menu

If you switch the TV off with the remote does it obey that command?so light will change to red?

Customer: replied 7 months ago.
unfortunately right now, I don't have the remote. when we powered it up about a week ago, the remote seemed not to be active. was told the batteries were new, but we got nothing. I figured I would just get the TV at my home and take the back off to look for a surge on either the power or main boards, but I see nothing at all. Back is still off the TV, so was just looking for what could be the issue.

You see we need to cover tests each test leads on to what avenue to go down like finding your way out of a maze, so without the remote then is there a MENU button on the set itself in the front?if not let me know what all the buttons are on the front of the set please

Expert:  Anthony_Infotech replied 7 months ago.

Yes if you have the back off thats not a problem do not touch anything though just switch ON and let me know if the MENU comes up

Customer: replied 7 months ago.
OK. Here is what I have. Red light flashes and then it is solid blue. No display at all.
Expert:  Anthony_Infotech replied 7 months ago.

Expert:  Anthony_Infotech replied 7 months ago.

No I am running checks with the data on this set please give me upto 5 mins to reply and also these are simply checks so I know what is wrong with the set when I know what is wrong I will let you know thanks

Its looking like the main-board has took a hit and will need to be replaced do you think you can do the work yourself?I will provide all the relevant info for that let me know

Before doing anything though please cycle the INPUT button of the TVs own remote and see if you pull in the sound from the cable or sat box
