Question about Televison & Video
I've read it's a common problem and that it's usually bad capacitors on the power supply board but I don't have any way to test them and none of them are popped up or leaking. And I was wondering witch ones usually need replacing
These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can vet an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs.

It's well worth replacing the capacitors, but this problem can be caused by a short on the power supply (Which is what the caps do). Most shorts that arise in power supplies are result of a shot transistor or diode and of course the electro caps. Check these while your changing the caps.
Good luck with it.

hello, amigo if the all the caps are godd then you have to replace the power supply board. don't try to fix it this is not an easy task. you are looking at almost $200.00 with tax an shipping. just go to google and type your tv model # and ask for the power supply board or just look for the part# on the board itself. good luck

Before you replace the power supply , check for swollen(rounded top)capacitors.
Also check and replace C126 47mfds/50 volts
And C520 1000mfds/16 volts
good luck and let me know if you need further help

The 24vdc is turn on by the signal from the main logic board, it is not always on, the standby 5vdc is always on. So yes it can be the power supply board is bad, but just to besure we need to find out if it is getting the turn on signal from the main board first.
You can have 24vdc at the inverter board and it will not light up the CCFL until it gets the signal from the main logic board to turn the lamps on (this is the STANDBY condition, the TV is on but the screen in not lit up util it see the video signal).
Send me good clean and clear pictures of the power supply board, firstname.lastname@example.org, connectors of the Power supply, bottom side of the board, then I may be able to tell you which pin is a control input pin. Most people will just throwing parts in and hope that they one of the parts will fix the problem. Used Power supply module for this TV is over $100. http://www.google.com/products?rlz=1T4GGIH_enUS282US283&q=delta+DPS-379AP&um=1&ie=UTF-8&ei=USsxTKn3J6TonQfFlJGEBA&sa=X&oi=product_result_group&ct=title&resnum=4&ved=0CCsQrQQwAw
