SOURCE: stand by light flashes red on powering up with remote and the green light flashes approx 15 or times before the screen illuminates.

thats pretty normal, it takes a good second or two to warm up and the display to turn on(at least0, you get the green flashes as you hold for on, 1 sec is a long time at times, lol, be patient, no problem with your tv!

SOURCE: Panasonic TX-P42X10B wont turn on - goes into standby

Hard to troubleshoot with just this info, the red light can be helpful if its 10 blinks repeating over and over replace the power supply first then the A board. Voltages check on the power supply would narrow down the culprit.
Post again if you measure the power supply voltages

Panasonic TX-L42E5B blinks 3 times which board is faulty
When an abnormality has occurred to the unit, the protection circuits operate and set the unit to stand by mode. At this
time the defective block can be identified by the number of blinks of the Power LED on the front panel of the unit.

Fault maybe on the A board 3.3V SOS give me your email & i send you the full timing chart.

Set up new tv - doesn't work
Warranty time. The TV most likely went into protection mode because a part went bad inside.
I would take it back to the store and exchange it for a new one. 90 day warranty policy.
Have them test the new one to make sure it works so you don't have to waste another trip.
Good Luck

Hdtv won't turn on
Can you count how many times it flashes ? It might flash like 6 times and pause for 2 sec and flash 6 times again. THen call a service comany and tell them this info and they might tell you what part inside is bad. They are not telling you this for you to replace but they might say something like oh 6 flashes is a Y board and we will have to order it.
Hope this helps
