Samsung UN48H4005

[abbottdave]

Anyone have any experience with the Samsung UN48h4005? All I get is a red LED in the remote sensor area on the front of the TV. I have 180VDC and 280VDC at connector CNL802 (to ground), and at connector CNM803 - 13VDC at pins 1, 3, 5 and 7, 3.3VDC at pin 2, .77 at pin 4, and 5.5 at pin 6. JP815 says 8V in standby,and 13V on, but it's always 13V whether you push the on-off button or not.

New information as well as the photos. When I disconnect the cable between the power supply and the main board, the backlights com on. No picture, but backlights.

What about if you just disconnect the TCON?

Re: Samsung UN48H4005

From what I can tell, this model does not have a separate TCON. The only other board is the board that is directly connected to the ribbon cables that come from the LCD panel.

So what happens if you disconnect it?

Hamie, no change when you disconnect the ribbon cable between the main board and the panel. And thank you thoma, I'll take a look at the manual and see if I can learn anything.

Quick update. Since I had backlights, I figured the power supply to be good. i purchased a main board on eBay for $12.00 (shipped), and it works. Thanks for your input.

Cheap enough and set working. Good outcome.
