Hello naomi1972,

If you checked the fuse, and it is good but the set remains off, this is an indication that you primary power supply has a problem. At this point you will need to have the schematic diagram to check the voltages on the power supply board. If you have a background in electronics you can do this with no problem, however if you do not have a background in electronics, I would suggest that you have a qualified TV repair person fix this TV for you.

My diagnosis of this TV is that the power supply board may be defective. This is the best I can offer with the information given.

I hope this helps,

Thank you,

Will not turn on


check main first, see if any lights are on or blinking also look in back and see if lights flashing. this means something if so, if dead set with no lights maybe main fuse.
