Question about Sharp Aquos LC-37HV4U 37 in. LCD HDTV
Good evening, i have this unit and it doesnt wanna turn on. All i see is the red light blinking and nothing happens. Sometimes when i press the power bottom stays steady then flashes.
Hold down the input button and volume - while the MAIN POWER BUTTON IS OFF. Then turn on the main power button while those are held down, the light on the tv & avc box will turn green, then immediately let off the 2 buttons and press volume +. Next step is to repeat the process about 20-40 times & the TV WILL WORK!. I have read that this may have something to do with the energy star compliant commads that can changed through the serial port.

Thank you, psxpirate25!!!! It worked. I had to repeat it about 35 times. It came up in a factory setup firmware mode. I could see the video behind it. Pressing buttons on the remote only switched between the settings menus. I power cycled it a couple of times and had to do another 35 times. Finally it worked! Totally awesome!

I had the same problem with my lc-37hv4u and i changed the following board: Sharp Main Board KB453DE XB453WJ. If your a little handy you can do it yourselfand save $150.00 bucks. The only proble is trying to find a new board, which will cost about $300.00 or if you can search the net and find a used one for much less, but make sure they are willing to take it back if it doesn't work. good luck.
