Phillips 42FD9932/17G 42" LCD TV won't turn on

[el3ctroded]

I get nothing but the red power LED.

I took the back off and nothing visible. I tested all the connectors coming from the main power supply and only 2 pins ever show power:
5vstby is powered all the time and 5vstby_sw goes on and off when you flip the power switch.

All the fuses are Ok.

This TV also has PCBs on 2 layers. The back comes off and there are the main power supply board, then another power supply board, the main logic board, the audio amp board, another logic board I don't know what is, and a small board that's not much more than a board for passing a few connections.

Then, and I'm not positive on how to get to these boards, there are some underneath. The only thing I can figure is that I have to take the LCD panel off to get to those, and I've tried but it doesn't want to come off; feels like it's gona break...

Pictures are coming...

Thanks!

Logic boards and audio amp. I can't get pics of the boards underneath all of these unless I figure out how to get the LCD panel off...

I think an over-all shot of the back this TV would be a big help. I'm having a little trouble locating much information on it. All the information I can find indicates it's a plasma, not an LCD tv.

It likely is a Plasma as it's got a glass screen.

Here's an overall shot. Notice one ribbon cable towards the right going underneath? It goes to the 2nd level of PCBs. So does a bunch of black wires at the top just to the right of the middle of the panel.

So far it says to unplug the y board and try to turn on. If that doesn't work, plug it back in and unplug x board. Is this the chassis number for your set.FTV1.9EE AA

i have replaced the 3 caps on the power board 2262,2263,2264 and i also have unpluged the video board but it still turns off, i have 2 tvs same model same issue when i turn it on with the remote it displays the image for about 2 seconds i could see it says vga on it but that is as far as it goes. the tvs were given to me by a lady and i really want to make at least one of them work with the parts of the other but unfortunately both tvs have the same issue. any other suggestions?

@ steve where can i find that?

Re: Phillips 42FD9932/17G 42" LCD TV won't turn on

Maybe on the sticker in your picture. Should give model # and Chassis # will be there also, or somewhere in it will be. Usually tv schematics are sorted by chassis as several models use the same chassis.

OK, here is one problem. there is no board on that TV called a 'video board'. It is no shame to not know what you are doing; we all started depending on someone to feed and change us.. Unless you are willing to take pictures of the TV, and identify the board you are talking about, you are wasting your time, our time, and probably trashing the TVs.

And here is the service manual. It's an FTV1.9DEAA chassis.

Which is the wrong board.

Download the service manual. It has excellent troubleshooting information.

I don't see any way to download the file on the site. Using Firefox... Click the blue down arrow, takes to preview of file, but no link to download it.

Using Firefox... Click the blue down arrow, takes to preview of file, but no link to download it.

After clicking the blue arrow and seeing the preview windows, there is a line that says

"This file can be downloaded free of charge from this site."

Just under that it says "Get Manual".

Click on "Get Manual".

If firefox doesn't work, try IE 8.

Yea, there's no Get Manual link in FF... Works in IE. Poorly designed site. I despise using IE, it's lame and slow compared to FF.

Not sure why you are having problems. I'm using the latest Firefox. Just to the left of the tag "Type PDF" is an umber circle with a down arrow. Clicking on that works for me.
