I got a DX-LCD32-09 from a friend. She says that is always warmed up slowly (about 1 minute) but it worked, until recently. Now when it powers up, it slowly gets to an all white screen (30 seconds). I looked at this forum (https://www.badcaps.net/forum/showth...ht=DX-LCD32-09) which seems similar but it was inconclusive. Here is what I have.
1. When I power up, the screen lights up erracticly (see Power-Up photo sequence).
2. If I cycle through the input modes, the screen is black on other modes.
2A. Unless I have a device attached to that input.
2B. Attached are photos showing the TV with a computer attached through the VGA and a VCR attached through the Y-R-W connectors.
2C. With devices attached, I have vertical lines
3. The sound is good. When playing the VHS tape, I can hear the sound fine, but the pictures is vertical lines.
4. I looked at referenced forum above and measured resistances on the T-Con. They were within tolerance as noted in that append. I did not measure voltages since that requires having the power board off to the side.
5. If I try menu options from the remote, all I get is the white screen.
5A. While I cannot see anything on the screen in menu mode, I can reference the user manual to make adjustments. For example, I can navigate to the picture controls and adjust brightness, color, contrast (at least the white screen changes).
5B. I navigated to the Setup-Restore Factory Defaults. I think I did right (twice) but no change.
5C. As noted above, the input select mode also works.
6. I looked at all my boards. I did not see any obvious capacitor problems (no burned/brown spots, no rising tops, no bloated sides).
So I know I have a bad board, but I don't know which one to focus on. I figure it is one of the main, inverter, or T-con. I am not suspecting the power. I tend not to think is is the main since functions seem to work, but I could be wrong on this. I am hoping that someone can help narrow down the board based on the images shown.
I realize that additional information may be required from me to further diagnose this problem. I just need a better starting place.
Thanks,
Ron
