First off I'd like to say reading a lot of past threads have given me a better understanding of what to look for and the inner workings of my TV, but here is my issue.
My TV set won't power on, I mean no display led, blinking ... nothing. So I went online to see what others were doing to fix their LCD. To make a long story short most individuals said the caps were bad, but not all would be, just the blown out and leaky ones. The only problem with this diagnosis was that I didn't have any bulging, leaky caps, at least not on the power board. So I just replaced the CapXon caps on the power supply board.
The TV didn't power on but I got a momentary flash off the inverter board, so I decided to check it out. After i took off the housing over the inverter board I saw that the two caps on it were bulging and leaking (the two purple caps in the photo), so I replaced those as well.
The TV still won't power up, but after reading about 7 hrs of threads I've conducted several test including
continuity of the power supply fuse - good
continuity of the power cord - good
I've also checked if there was any current actually coming from the power supply, so I tested all the outputs from the power supply board to the inverter board. On that side of the board is 24V and the ground, which tested with a multimeter gave me 24V for each wire.
I then checked the other side of the power board which as the 5V, 12V standby and 24V. Besides the 12V showing a voltage of 2.635 and stand by showing a voltage of 2.413 the 5V and the 24V showed up on the power supply as well as the main board.
So now I'm hear ...
I've included a bunch a pics
Any help will be appreciate, thank you and sorry for the long description of my problem.
P.S.
1. I used generic caps for the inverter board being that I got them from an electronic shop and the guy said that they were good for the tv
2. I used 2 caps from radio shack, 1000uf 25V and 470uf 35V, which are the exact uf but higher voltage than the original but its temp resistance isn't 105c but 85c
