Acoustic Solutions LCD32762HDF stuck in standby

Dansford:
Hi, I have the TV listed above with the power supply 17pw20.1 . The problem is that the TV does not turn on , the blue  standby indicator just dimms when tv is commanded on by remote or buttons. From what I have read the problem could possibly be the power supply board which needs repairing or replacing which is understandable and can be fixed by replacing some components.

I've inspected the board and none of the the capacitors appear to be bulging or at fault but looks can be decieving  :dubbio:. Can anyone help me identify the components at fault ? I can solder pretty well so if I can repair it would be great. I have basic tools i.e a standard digital multimeter, soldering iron etc.

Also components c878 and c877 on the schematic are described as 12n 630v and on the internet 15n 630v and according to the numbers 1.5uf 630v but it confuses me as I cant find them anywhere online  :wacko:, can anyone also help identify the correct component and a possible place to buy them. I like eBay  :cheesy1:

Thanks in advance  :brinda:

Dansford.

Hi, Thnx 4 reply Sparky. I know the location of the components, I just need to know if they are responsible for my specific problem. I dont want to spend time and money replacing perfectly functional components. Also finding those specific 2 polypropylene capacitors could prove to be an issue if i dont know the exact model numbers ?  :dubbio:

I've also read that other components could be at fault, is it possible to identify which specific component is responsible for this issue. (is it the c877 c878 caps ??)

Thnx  :happy:.

Dansford

sparky:
you will have to take out and measure with
 a capactaince meter c877 c878

There are four 85 degree caps on the P.S. that can give this problem . Had a similar fault and it was the Smoothing block faulty, the rivets were arcing.
