From the information you have provided failed capacitors in the power supply is likely causing the problem. The safety circuitry shuts the TV set down when it detects a problem. This model of TV has over 2,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. The repair should cost about $250 if carried into a TV repair shop. A small TV repair shop will often charge less than a large repair facility.

Is my tv main board bad


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.

I am thinking about buying a used 65 sharp


I wouldn't recommend buying it unless it came with some type of warranty.
The most common thing you would be looking at for repairs if something goes wrong would be the Backlight Inverter Board or the Power Supply Board. It's what powers the big screen like that. Replacement board for one of them would be well over $200. And we're not talking about labor on top of that from the repair shop.
If you get it, try to get warranty with it. Add on extended warranty if possible.

Hook up Avertec 3200 to Sharp Aqueous TV


After I found the manual somewhere on the internet, I realized that it is already available here. (Lucky you!)

I could not find a specific manual for your Aquos TV (which model?). Look into your manual, and see if there is an option to connect via VGA of HDMI for video
If you want to use your TV speakers, it depends what audio input options you have on your TV. You might need a cable like this:

The red/white connectors into your TV, the 2.5mm plug into your computer.

Sharp 37 inch aqous tv power button blinking red


If the blinking light seems to be blinking in a pattern, then it is an error code. The end result in any case, is the main power supply is not functioning properly, or the backlight power supply has a problem.
