Large screen, won't turn on. The power indicator little green light comes on but no picture or sound. Any fuses or known issues to look for on this one? Thanks, Ray.

See if either or both the fuses F9a04 and F9a05 open. These fuses are for the +24v and -24v which feed to the STK392-570 convergence chips.Cool

I am a motorcycle mechanic & CAN fix things but where in the tv are these fuses you are telling me to check? Thanks, Ray.

Inside the TV on the circuit boards are things called "parts". Each part on the board is assigned a "Location" number that is stamped/silk screened onto the top (and/or bottom) of the board.
You may have to carefully rearrange the dust to enable you to read these numbers. Simply match the location number assigned to the part in question.
If necessary, "Google" the part you are attempting to find (ie, "fuse"), choose "image" and you should see many pix of the many types. Alternatively, visit a parts site like Digi Key or Mouser, they have pix of many types of fuses.
