Led blinking Three times means 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. If you have electronic knowledge you may be able to fix it. Let me know if I could help you further.
Hope this helps.

my tv, when turned on via remote or manually pressing the power button on tv does not turn on. The TV power light powers on red but makes a clicking sound as if if were turning itself off after power up. (clicks on then clicks off) Humm? What could the problem be? Is there a repair part that is needed? If so. what might that be and is there a schematic or some sort of diagram to show how this issue can be resolved?

IF coming in via, the "Dish" networked receiver, please check that this volume is turned way up, on the TV. and then control the the Volume, with the Dish Remote, often this is a problem, as one is turned down, and the other cannot turn that up, simply try syncing the Volume controls, UP on TV, control the Audio with dish remote. thats all i can think of. Check by feeding a signal IN from an AV, source, ie: Yellow, Video, & Red& White, Audio. Turn TV UP and check, IF it responds to this all is well. If NOT then you do indeed have a fault, with the TV.

You have a frame collapse problem. Line, EHT, power supply, video and sound stages are all functioning. Check frame output ic for dry joints, resolder all pins. HT supply for output ic's derived from line stage check for open circuit safety resistors around line output transformer, if you find any then frame output ic will also be suspect. WARNING Very high voltages exist around the line stage. Make cold tests with Ohm meter with set unpluged from mains supply.

check the circuit board, resolder all the Ic pins specially in IC jungle area.

I would try a power drain:  Unplug the TV's power cable so the TV is not grounded to the house.  Then press and hold in the TV's own power button for one minute to drain the capacitors. Plug the TV back in and see what happens.  If the TV will still not turn on, I would say you have a problem with the TV's mainboard as a dead power supply will not light any LED's for you.

Hi: Your set has a power or high voltage circuit problem. Depending on parts cost it may or may not be expensive to repair. Get an estimate from a reliable repair tech. Good Luck.
