Usually 3 blinks means convergence,however it should continue to blink. Not shut off. You will probaly need a service manual you can get one through this link for 10.99 along with free unlimited support. If you choose to get your manual you will have to go back to the site and request that they email it to you instead of mailing it out. With your manual they will also email instructions on how to obtain your free support. . Youre probaly looking at a regulator that feeds the IC. I am one of the support techs at servicemanuals also. Heres there link,

Pt-53wx53 Panasonic Projection TV Turns off

OK< likely one of the new chips are bad or when soldered in you shorted pins at that time----3 blinks is short protection and you are going to find ONE of the light blue 2.2 ohm resistors is open (usually discolored in middle).

Having changed hundreds of chips in this model once in a while you get a new one that is bad---replace both again.

How did you get at them----remove the board or pull the light box?

Most of these have a shutdown feature built in and if you unplug the set, plug it back in and turn it on manually look carefully at the power light on the front when you turn the set OFF.

It should blink a specific sequence: 3 blinks, a pause and 3 blinks etc.

3,3 and 5,5 are the most common and mean different things are wrong.

Let me know if you are able to see the error code.

projection TV`s have integrated protection circuits
built into the circuit design, these circuits turn the
power off automatically when a fault has bin detected this
is in order to prevent a more costly repair, these circuits monitor
power supply , vertical and horizontal deflection
over voltage, or x ray, and also faults with convergence circuits.
Diagnosing these faults require test equipment and a good knowledge of
electronic repair techniques, and also a repair manual.

Turns on and within a second goes out

Bad capacitors. They're cheap. Look for the ones closest to where the power cord comes in to the main pcb board. This will be your power supply circuit. Change them! They're probably dried out. If they're bubbled up, they're also bad. They're so cheap though, just replace them all.

Power problem

Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
