Re: 50 inch Rca led problem

So can I jumper from the main board to the bl on pin to bypass adjust pin which I think is dimmer. Also i unplugged all the led strips and individually tried each strip and same shutdown. I don't believe I had a short in all 4 strips. Woudnt it point upstream to the culprit ( I don't know jack about electronics but all 4?could it be main board or p supply ? But why does all work if take the backlight out of circuit?). I wish the problem was bad caps I would have had this fixed a month ago ��

Re: 50 inch Rca led problem

Does no resistance mean open circuit or bad connection?

Re: 50 inch Rca led problem

I pulled the harness from the board. Black prone to chassis red probe on all led wires at 200 ohms. I had a constant 1 across the harness no change on each pin. I did that to the male pins on the led light manifold . Using the wire harness is better idea

Re: 50 inch Rca led problem

I tried each led strip separately wouldn't that mean they are all bad? And the other end of the led harness comes out of the power board does that mean the power and inverter are on the same board? I am not real tech savvy please excuse stupid questions.

Thanks

I have a 50lbrq45 I have torn it down completley.
First symptoms red standby light would change to blue no audio or video wouldn't turn off. After tearing it down checking voltages everywhere I baked the main board at 400 degrees for 9 mins. The did the flashlight test and found I had picture and audio but no backlight. One thing I noticed is I could turn the set off after I baked the board. I am not 100 percent baking the board did anything and maybe I turned off before the usual shutdown occurs. I only have pic and sound when I unplug the wire lead for the led,s otherwise they all flash...
