Hi, I'm in need of help identifying the part located at BB804 on my tvs power board( cold section near led driver. Power board model PW. 108W2. 683.
. Please help! Thanx

Did you mean DB801, the component a bit out of sight, up and to the right of BB804 in your image, as the connections seem a bit rough?
Looking at a blown up image of the board (see below) the component type for a DB801 is MBRB1050CT. At least I think it is but my eyes aren't as good as they used to be, so you'd better double check
(click on image)
Apologies if it is BB804 you mean. Have you removed the diode to see if there's any model type markings on the underside of the diode case?
If you don't get an exact answer it may be quicker and easier to just get a replacement board. Some seem to be very cheap. You may have to verify that they're the exact same full board number as shown on the sticker on the board though

Heya bud, Thanx for the reply. BB804 is the spot I'm referring to. Down to the right of the schottky . The little guy that Google says is a diode but then other times says its a ferrite bead. I'm teaching myself w this tv. So a new board is last resort
If you disconnect one leg of BB04 from the board and measure it using an Ohmmeter i.e. meter lead to each side of the component, if it's a diode, it should measure low resistance when measuring it in one direction and high resistance if you swap the meter leads over and measure it the other way
If it's a ferrite bead it should test low resistance when measured in both directions.
The above is if the component is OK and not faulty i.e. OL or infinite Ohms on the Ohmmeter
