Sharp LC32D59U power supply pinout

[aaronwt6]

Does anyone have the pin layout for this power supply. I want to force it on to test but none of the 3 plugs are labeled. The backlight inveter is marked on the other end but nothing going to the control board. Any help would be greatly appreciated.

Thanks,

Aaron

Thanks again budm. I found the schematic in that document and the power supply tested out good. Now, to find a control board for it. Nothing on Ebay right now.

Well, I gave the eeprom a stab to no avail. Have 3.3V going to both the side buttons and the remote sensor so I figure it's got to be the main. Unsure what to check for on there given the fact that I have power going to the buttons but I'm certainly open for suggestions. I've been unable to locate a used one anywhere.

Thanks,

Aaron

This isn't a Sharp TV, it's an AmTRAN re-badge which Sharp buy in... anyway it's usually the same fault that kills Vizio main boards (AmTRAN also make these): corrupted flash. Hopefully, you can find a replacement flash chip.
Ugh, crap caps all over that PSU. Doesn't live up to the Sharp name at all. Absolute garbage.

Ok. This makes a whole lot of sense now. Not sure which is the flash chip but the eeprom replacement had no effect. It certainly has the same symptoms of many of the Vizios I've dealt with.


The power supply is working ok at least.....for now.
