Hello Dylan, for what you are saying, your TV has suffered a shock of tension, it is probable that the current input fuse has been burned or in the worst case the power supply has been damaged.
If you are going to see if the fuse is burned, just replace it with one of EQUAL VALUE, neither bigger nor smaller
If you replace it and it burns, I suggest you look for a specialized technical service
I hope you can solve the problem

Hola Dylan, por lo que comentas, tu televisor ha sufrido un golpe de tension, es probable que se haya quemado el fusible de entrada de corriente o en el peor de los casos se haya da?ado la fuente de alimentacion
Si vas a ver si el fusible esta quemado, Solamente reemplazalo por uno de IGUAL VALOR, ni mas grande ni mas chico
Si lo reemplazas y se quema, te sugiero busques un servico tecnico especializado
Espero que puedas resolver el problema
Saludos Franco Dosil

I had one that was doing the same. swapped out a back light inverter board... fixed it. this doesn't mean that my fix will be your answer. to help find which one is of the 2 sides is bad..unplug power to the board one side at a time & half the lcd will fire up. good luck
SOURCE: My Sharp Aquos LC-52D64U shut off by itself, and
sounds like power supply/ohm supplies for repair in uk
SOURCE: I have a sharp Aquos
Do you get any sound at all?
I had a similar problem. I had a 52"
RCArear projection tv. It
would do this when I initially turned on the television, but then after a few
"on/off, on/off, on/off" cycles it would stay on. Eventually it
started doing it more; until finally there was a spark and that was it. The tv
was dead.The bloggers called it "the blinking green light of death" (because
of green light on the panel).The
power board is going out.ALSO holding down the Input and Menu buttons afterward will give you
some diagnostic information via 2 sets of blinking indicator lights. You may very well
have issues with capacitors on this set being that it is or very similar to the
V26 chassis. Since I have spare test lamps laying around, I would normally try
that first. If the lamp still would not stay lit, I would then suspect the
electrical chassis (capacitors). When I suspect the chassis, I can usually
verify it by pulling it out and partially disassemble it and find blown capacitors
Solution

The PNL-POW (LCD panel Power) and the PS-ON will be 0V until the main board send out the signal to turn them on, it is working.
Do you get backlights?
Did you check the fuses on the Inverter board? You power supply is working.
