My panasonic projection tv 60'' has a power but auto shutoff after 5 seconds then blink red light 3 times


Dead power supply. I recommend a new tv rather than throw good money after this old thing. A new power supply will cost $200 or so plus installation. Sometimes dead power supplies take other components with them as the voltage surges.

FLASHING POWER RED BUTTON 7 TIMES


I believe that is a bad power supply board. You can unplug set ,open the back access panel and look for swollen electrolytic capacitors they will most likely be slightly rounded on top instead of flat top like the others.Not sure if just replacing caps is enough we mainly swap out whole board.Some models' replacement power supply is slightly different from original in that a couple of the plugs are in different spots and require an extension cable.

Panasonic PT-53TWD63, TV will not turn on, Red power light blinks


It is most deffinately a convergence chip issue. The die for no reason. They can be bought online for around $10 dollars and anyone with experience with soldering can replace them pretty easily. I have done it.

In the majority of cases when you'are unable to power up the TV, the power supply would the first place to start.
