Sharp lc-c3742u will not power-on can i cut wires and unite them bypassing what it looks like a hot-dog

SOURCE: sharp television will not power on

Check the internal fuses AFTER eliminating power supply, power strip, etc. But it sounds like it is in sleep mode. Try unplugging it, wait 5 minutes then power up while holding the power button in.
Good Luck!

It's a power supply related problem. When it turns itself off, this it called protection mode. The TV automatically turns off to protect other parts form being damaged.
The most common problem is the Power Supply Unit or the Backlight Inverter Board.
You may have to take the TV to a repair shop to find out which one is bad. Paying a repair shop to replace the board for you maybe more than the TV is worth. If you let them diagnose it and you replace the bad circuit board yourself, it would be cheaper.

Here's a place I use to get parts for TVs:

The problem is the repair shop may charge you double or three times of what the part costs at the web site link above. Then, plus labor. I just want to save you money. :)
