Is the set in standby ?usually a red light

Ask Your Own TV Question
Customer reply replied 4 months ago
No standby light or anything on the front, just a click,click pause click,click pause etc
TV Technician: Anthony_Infotech, Technician replied 4 months ago

Sounds like a primary power-board issue, as there is no power-light at all this board will likely need to be replaced ,one voltage check would be needed just to see if the main-board is receiving 5vdc, would you consider doing this yourself?

Ask Your Own TV Question
TV Technician: Anthony_Infotech, Technician replied 4 months ago

I am not sure at the cost of a board but around $80_$100

Ask Your Own TV Question
Customer reply replied 4 months ago
I cannot check right now for voltage but there is a red light on one of the boards on the back that is blinking
Customer reply replied 4 months ago
every time the board does a double click the light goes on and off on the board on the back
TV Technician: Anthony_Infotech, Technician replied 4 months ago

Yes that is the logic board and its normal for it to blink, sounds like power-board ,the set is not reporting a fault otherwise the light would be blinking so something odd has happened, has it been subject to storm damage?

Ask Your Own TV Question
Customer reply replied 4 months ago
No storm damage that I know of
Customer reply replied 4 months ago
If it is not the power board what else could it be?
TV Technician: Anthony_Infotech, Technician replied 4 months ago

Usually the set will report a problem with the blinking so its either power or a main-board issue here one of those boards will need to be replaced

Ask Your Own TV Question
TV Technician: Anthony_Infotech, Technician replied 4 months ago

If its been subject to a surge or storm damage then both could be bad, so you are looking potentially at a $200 input which may not be a good idea for a set of this age

Ask Your Own TV Question
Customer reply replied 4 months ago
where is the main board located?
TV Technician: Anthony_Infotech, Technician replied 4 months ago

The main-board is the one with all the AV inputs attached

Ask Your Own TV Question
TV Technician: Anthony_Infotech, Technician replied 4 months ago

Usually its in the bottom right hand corner

Ask Your Own TV Question
Customer reply replied 4 months ago
gotcha, is there any way to test the main board-I do not want to purchase both boards if I do not have to, and if I were to replace one board first which one would you replace first?
TV Technician: Anthony_Infotech, Technician replied 4 months ago

No that is the catch no way to check effectively either board, I can because I have the expensive test gear but you have no chance the main-board is a data board anyhow data boards can't be checked and the power-board can only be checked properly on a jig

Ask Your Own TV Question
TV Technician: Anthony_Infotech, Technician replied 4 months ago

The pointers are what you told me, no power light lit or blinking

Ask Your Own TV Question
Customer reply replied 4 months ago
Which one would you replace first?
TV Technician: Anthony_Infotech, Technician replied 4 months ago

As it stands the main-board, but ideally a check needs to be made with a voltmeter

Ask Your Own TV Question
TV Technician: Anthony_Infotech, Technician replied 4 months ago

The check will just make things a bit clearer

No that is the logic board it does different work and the power-light would blink if this was bad it WONT blink if the main-board is bad this is the board covered by the black metal over the INPUTs,I think you can see about a quarter of it sticking out the top,
