silberzahn1 just to clarify, we are talking about a Sharp Aquos LC70LE732U?

Sharp Aquos. TV suddenly went off, the power button blinks 1 fast then 1 slow.

pulled back off, checked diodes used compressed air can (dust off) and blew off the dust. Tried the reset, unplug hold input and vol down then plugged in, name sharp briefly appears before going black and back to the blinking…

silberzahn1 the 2 slow 5 fast flashing LED signifies a Panel power supply error. Unplug your set and open it up. then check the power supply for anything obvious like leaking or domed capacitors etc. Post some images of what you see with your question. For that use this guide. It will allow us to see what you see.
