Try new caps.

Thanks! I will keep this updated with my progress,

Try new caps.

Replaced them, still nothing. When I plug the tv in, the power light flashes blue for second and then turns off.

Any ideas?

What Voltage do you get at 5V pins?
Pictures of your board?

Same board as original post, will try to get a couple uploaded ASAP!

Voltage readings were correct according to my friend who put in the new capacitors at the 5v pins. I can test them but, would probably need help, lol!

Just odd that the power light does a quick blue flash and then nothing.

Thanks for the help!

If the 5V supplied to the main board is steady but the main board is not staying on, then the problem will be in the man board, but we need to find out if the 5V is OK or not first, then we will have to check and see if the main board also sends the command signals to the power supply board or not.
I cannot see all the labels for all the pins which is important info we need.

Can you look at the bottom side of the board, sometime they put the labels there?

Oh man, there is nothing there either!
Any thing on the main board side?

OK, nothing on the main board either.
I will have to trace the connection on the bottom side of the power supply board next.
BTW, there are some 3-pin Voltage regulator ICs on the main board that you can do some Voltage testing to see if they are OK or not.
See the link on how to test them under my signature.

Appreciate the help! I will try to test those and will let you know! Thanks

Just be real careful since you will be working in the primary side so do not let the probes slip on you and do not touch anything with your hands.

I think my meter is messed up because I am not reading anything. My friend who did the capacitor change, measured the voltage while I was there and everything was reading correct. He said the board was working like it should. Brought it home, hooked it back up and now it just does a quick blue power light flash and nothing.

It's my brothers old tv, wondering of he gave me the correct power cord? It's a 10amp 125v cord.

TV uses <3A of power.
