58 inch Samsung plasma will not turn on

Samsung pn58c8000yf. TV will not turn on. I do have the red standby light. Power supply comes on for about 1 second and then turns off for about 4 seconds with the relay clicking. I changed the power supply board with one I borrowed but still had the same issue. Both the X and Y boards are unplugged. I did check the 5.3 vdc and it is fine. I'm thinking its the main board does this sound correct

Yes based on your testing it appears that the power supply is at fault solely and you can opt to attempt a repair or replace it altogether. Unfortunately you will not be certain that the main board does not also need to be replaced until you have repaired the power supply.

I have a hitachi 55pma550 plasma tv.when I turn on the main switch red light comes on standby. But when I turn on tv the red red light on stand by turns green only for 10 seconds and goes red no picture...


It's most likely the smps. You'll first need to check voltages at CN63, pin #1-(+5v), 3-(+3.3v) and pin 8-(+6v) Also check CNPPS, pin 1-(+30v), 4-(+5v), 8-(+12v), 12-(+10v) absent these values and the power supply is clearly the problem.

Is the red light suppose to stay on when you turn off the tv with the remote?


Yes it is supposed to stay on. This is the standby light. The television still draws power as do many electronic devices when not turned on and when in standby. If you do not want the red light to stay on you will have to unplug the television.

Only comes on for a second power light blinks red 4 times, stops then repeats


4 times standby red light blinking is an error code that shows that Fan problem in tv. Check following possible causes of that problem in tv:
1- Fan 1-4 power is not supplied. (AGU board).
2- Fan caught wires or harnesses.
3- Fan connector is not attached securely.
Thanks.

Samsung HLP4674W - changed bulb - still no picture - lights flash


If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.

AKAI 32" LCD HDTV WILL NOT TURN ON


The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com
